Mirissa Whale Watching

Almost everything true about Mirissa follows from one fact about the sea floor. At Sri Lanka's southern extremity the continental shelf is narrow, and the drop into deep ocean happens close enough to land that a small boat can reach it, look for blue whales and be back at the quay before lunch. Nowhere else offers that combination quite so conveniently. In most parts of the world where blue whales are watched, reaching them is an expedition.

The second half of that sentence is the part the operators leave out. A feeding ground within an hour or two of a harbour is not just a gift to visitors; it is a low barrier to entry. Anyone with a hull, an engine and a laminated sign can sell tickets, and over the past couple of decades a great many people have. The result is a fleet that departs together, searches together, converges on whatever the first skipper finds, and operates almost entirely beyond the reach of anyone empowered to stop it. Rules exist. Out on the water, on a busy February morning, they are voluntary.

So the honest framing of a morning here is this: the whales are a matter of luck and season, and the quality of the experience is a matter of which boat you happen to be standing on. That difference is not about cushioned seats or whether breakfast comes in a box. It is about whether the vessel approaches an animal or hunts it. A boat that holds its distance and waits will show you more than one that races, and it will not turn a feeding whale away from its own route. Choosing well is the only real decision a visitor makes, and it is made on shore, before any money changes hands.

Why the whales are here, and what the shelf has to do with it

Sri Lanka sits on a shallow platform that extends some way out on most of its coasts. Off the far south, near Dondra Head, that platform pinches in and the sea floor falls steeply away into genuinely deep ocean. Depth on its own does not attract whales. What matters is what deep water does when it meets a slope: currents driven along the coast are forced upwards, and the cold, nutrient-heavy water from below is lifted towards the light.

That lifting is the whole engine. Nutrients in sunlit water produce plankton blooms, blooms feed swarms of krill, and krill are what a blue whale exists to eat. The seasonal reversal of the monsoon in the northern Indian Ocean drives this cycle, which is why the productive periods are seasonal rather than constant, and why the whales move around the island rather than staying in one bay all year.

Depth serves a second animal too. Sperm whales hunt squid far below the surface, in the dark, and they need the water column to do it. The same steep drop that makes krill available to one species makes deep diving possible for the other. Mirissa is simply the working harbour closest to that piece of water, and the industry assembled around the geography.

The blue whale, and why this population is unusual

Descriptions of the size of a blue whale do not survive contact with the sea, where an animal at the surface is showing you very little of itself. The comparison that works is the one available on the day: a blue whale is comfortably longer than the boat that carried you out to see it.

What makes the animals off this coast interesting to science is their schedule. Blue whales in most oceans undertake enormous seasonal journeys, feeding in cold high latitudes and breeding in the warm tropics, so they are present at any given place only for part of the year. The population in these waters does not appear to work that way. It seems to remain in the northern Indian Ocean, shifting around the region as the monsoon shifts the productive water, rather than commuting to polar seas. Whether they are a distinct population and how they relate to blue whales elsewhere are still live questions, and the researchers who work here identify individuals from photographs of their markings rather than from counts anyone should quote.

For a visitor the practical consequence is simple. This is not a migration corridor with a narrow window when the animals stream past. It is a feeding region that becomes usable to boats when the sea is calm enough to work.

The season, and why it runs when it does

Boats operate from roughly November to April. The reason is weather rather than whales. Through the middle of the year, from roughly May until September, the south-west monsoon drives straight onto this coast, the sea gets big and disorganised, and small vessels have no business being out in it looking for anything. In the other half of the year the weather system reverses, this coast falls into the lee, and mornings are calm enough for a wooden boat full of passengers.

Two qualifications matter more than the months. The first is that the season varies from year to year at both ends. Monsoons do not arrive on dates, and a November that works one year can be unusable the next, so anyone planning around the fringes should treat the boat as a possibility rather than a fixture. The middle of the season is the safer bet than either edge.

The second is that calm is relative. Even in the heart of the season there are rough mornings, and there are days when responsible operators do not sail while less careful ones do. A cancellation is not an operator failing you. It is frequently the best sign you will get about how the operator makes decisions.

The single most effective thing anyone can do to improve their odds costs nothing but a night: plan two mornings rather than one. Whale watching rewards a second attempt more than almost any other activity on the island, because the variables that ruin a trip, being weather and animal movement, are largely independent from one day to the next.

The harbour before dawn

The fleet sails at six, and the morning starts a good deal earlier than that. Mirissa harbour is a fisheries harbour first, with the whale boats fitted in around the working boats, and at half past four it is already busy with ice, diesel, crates and the landing of fish. Vans arrive at the gate in a steady stream. Passengers get out into the dark and stand about looking for someone holding a sign.

The quay is where the first thing goes wrong for people who booked casually. Tickets are sold by guesthouses, by drivers, by agents on the beach and by men who appear at the harbour gate itself, and several layers of that chain can sit between a passenger and the boat they eventually board. Somebody with a clipboard will take a name and point at a vessel, and it may not be the vessel that was described the previous evening. The defence is unglamorous and effective: know the name of the boat and the name of the operator, written down, and decline to board anything else without an explanation.

Boarding is worth thinking about in advance. Boats moor two or three deep along the wall, so reaching the outer one means stepping across the decks of the others in the dark, over gunwales, on wet timber. Straightforward for most people, and genuinely difficult for anyone unsteady on their feet.

Look for two things while boarding. Are there life jackets, in reachable numbers, including small sizes if children are aboard. And does anybody deliver a briefing before the lines come off. A crew that explains where to sit, where the life jackets are and what will happen when an animal is sighted is usually a crew that thinks about the rest of it too.

The run out, and how the search works

The whole fleet leaves within a few minutes of each other, which makes the harbour mouth briefly chaotic and the first stretch of sea unexpectedly crowded. The light comes up during the run out. The coast falls away astern, the lighthouse at the southern tip becomes a mark on the quarter, and the boats spread out as they head for deeper water.

Then the searching begins, and it is less romantic than it sounds. A crewman goes up onto the wheelhouse roof or the bow with binoculars and looks for a blow: the vertical column of vapour a whale leaves hanging when it exhales, which in still morning air is visible from a long way off and is almost always the first sign of anything. Passengers are welcome to look as well, and the ones who do tend to enjoy the morning more, regardless of what turns up.

What is not visible from the deck is the radio. Skippers talk to one another continuously, and a blow reported by one boat becomes known to the fleet within minutes. This is a genuine advantage in raw terms, because thirty vessels sweeping different water find more than one vessel would. It is also the mechanism that produces every problem described further down this page, because the news travels faster than the whale does, and a discovery made by one boat becomes a destination for many.

The whole trip runs between three and five hours, much of it transit. The sea also stiffens as the morning warms and the breeze fills in, so the return leg is usually the lumpiest part of the day.

What a blue whale sighting is actually like

This needs saying plainly, because the gap between the advertising and the morning is the commonest disappointment here, and it is entirely avoidable by knowing in advance what the animal does.

A blue whale at the surface is breathing, not performing. The sequence goes like this. A blow appears, tall and narrow, and hangs for a second or two. Then a long dark back appears and keeps appearing, rolling forward at walking pace, far longer than instinct says a back should be. Very late in that roll, almost at the end of the animal, a surprisingly tiny dorsal fin comes up. The whale blows a few more times, then arches its back higher, and goes down. Sometimes, on a deeper dive, the tail comes clear of the water. Then there is nothing for several minutes.

That is the sighting. Seen from a reasonable distance it is a dark shape, a puff of vapour and a wake, and people whose expectations were formed by photographs are quietly deflated for about thirty seconds. What tends to change their minds is the scale arriving late, and the sound. On a calm morning the blow is audible across open water as a deep, gusty exhalation, and it carries a smell that nobody forgets.

Be realistic about photographs. The images that sell these trips are shot from drones and research vessels, over years, by people whose job it is. A phone will produce grey sea with a smudge in it. Binoculars beat a long lens on a rolling deck, and passengers who put the camera down after two attempts generally have the better morning.

The multi-minute dive is also where boat behaviour is decided. A whale down for several minutes will come up somewhere, and the difference between an operator who waits to find out and one who guesses and drives to the guess is the whole subject of this article.

Sperm whales, which are underrated here

Sperm whales get a fraction of the marketing and are, on their day, the more satisfying encounter of the two. They are the deep divers, hunting squid far below in complete darkness, and they spend long spells at the surface between dives recovering, lying more or less still in a way that looks like an animal resting on the water because that is exactly what it is.

They are recognisable without expertise. The blow is bushy rather than columnar, and it comes out forward and to the left instead of straight up, because of the way the animal's blowhole sits. The visible body is a blunt grey log with a wrinkled surface and a low hump rather than a proper fin. When a sperm whale finally goes down for a deep dive it lifts its tail clear of the water, which is the picture everybody wants and the one moment on the trip where a camera earns itself.

They are also social. Groups of females with young travel together, and coming upon a gathering of them at the surface is a genuine event. Because such a group stays put rather than travelling steadily, a boat that stops at a distance and switches off can watch for a long time without troubling anything. That is this trip at its best, and it happens more often with sperm whales than with blues.

Bryde's whales, and the outside chances

Bryde's whales are the third species regularly encountered, smaller than the other two, tropical, and resident in warm water year-round rather than migratory. They feed on shoaling fish as well as krill, which often brings them nearer to shore than the blues, so the sighting can be closer.

They are also frustrating, and worth understanding for what they do to skippers. A Bryde's whale surfaces on no discernible pattern, changes direction underwater, and reappears somewhere nobody predicted. There is no comfortable way to sit with one at a distance and wait, which is precisely why they tempt crews into repositioning again and again, engine on, chasing a moving target around a patch of sea. A boat doing that is worse for the animal and worse for the passengers, who spend the encounter being thrown about.

Beyond those three, the sea off the south holds occasional surprises. Other large whales are reported from time to time, orca turn up rarely and memorably, and manta rays, whale sharks and turtles are possible without being anything to plan for. Flying fish are near-constant company. So, less happily, is the plastic and fishing debris that collects in lines on the surface.

Spinner dolphins, the reliable part of the morning

Dolphins are the reason many blank whale mornings are not blank at all. Spinner dolphins move in large, fast, noisy schools and will readily come to a boat. They ride the pressure wave at the bow, which puts them close enough to see individual animals clearly, and they leap, some of those leaps carrying the spinning rotation the species is named for.

For children, and for anyone who found the distant grey back underwhelming, this is usually the part of the trip they talk about afterwards. It is also more predictable than the whales, since the schools tend to be encountered nearer shore and earlier in the run.

The behaviour to watch for is the same as with the whales, in miniature. A well-handled boat positions itself alongside or ahead of the school's course, drops to idle, and lets the animals decide whether to come in and ride. A badly handled one drives into the middle of the group, splits it, and then circles back through it repeatedly while everyone photographs. Dolphins are resilient and will tolerate a lot, which is not an argument that they should have to.

Seasickness, which ruins more trips here than anything else

More Mirissa mornings are wrecked by nausea than by an absence of whales, and almost all of it is preventable. This deserves more space than it usually gets.

Understand first why this particular boat trip catches people out. The water beyond the harbour is open ocean, and the motion is a slow, deep, rolling procession rather than the short choppiness of a lake or a sheltered ferry crossing. People who have never been ill on a ship are regularly ill here. Worse, the motion changes character exactly when the interesting thing happens: a boat under way and pointing into the swell is relatively steady, while a boat stopped at a sighting sits side-on and rolls, and does so surrounded by the wash of other boats. That is the moment most passengers go over.

The contributing factors are all avoidable. Diesel exhaust hangs around the stern, the cabin has no horizon in it, and phone screens are a reliable trigger. Breakfast is often served on board, and the smell of it in a rolling boat is enough on its own. Sickness is socially contagious too, and one person being ill in an enclosed space frequently starts a sequence.

Before boarding

• Take something, and take it early. Motion sickness medication works as prevention and barely works as treatment. It has to be in the system before the boat moves, which for most preparations means at least an hour ahead, and for some the night before. Taking a tablet after the first wave of queasiness is close to pointless.
• Eat a small, plain breakfast. Going out with nothing inside you offers no protection at all and makes the retching worse if it comes.
• Do not drink heavily the night before. Mirissa's beach bars and a six o'clock sailing are a poor combination, and dehydration reliably makes motion sickness worse.
• Bring a bag, water and a spare shirt. Boats carry buckets and little else.

On board

• Sit low and near the middle of the boat, where the pitching and rolling are least. The stern is the fume trap and the bow is the trampoline.
• Stay outside in moving air. The cabin is the worst place on the vessel and lying down in it is the classic mistake.
• Look at something distant and stable. The horizon, or the land while it is still visible. Not the deck, not a book, not a phone.
• If it starts, go to the rail on the downwind side, and ask which side that is rather than guessing. Stay outside afterwards, keep sipping water, and expect to feel better within a few minutes of an episode.

Anyone who knows they are prone to this should also weigh whether to go at all. A trip of three to five hours has no exit, the boat will not turn back for one passenger, and a bad morning at sea is genuinely miserable rather than merely uncomfortable. Larger vessels roll less, the earlier weeks of a calm spell are gentler than a windy one, and a companion who is likely to be ill changes the shape of everyone else's morning.

The guidelines, and what breaking them looks like from the deck

Sri Lanka does have published guidance for watching marine mammals, issued through the wildlife authorities, and its principles are consistent with practice elsewhere in the world. Rather than quoting figures that shift between documents and species, it is more useful to know the shape of the rules, because the shape is what is visible from a passenger seat.

• Boats should stay outside a minimum distance, and a larger one where a mother and calf are involved.
• Approach should be from behind and slightly to the side, at a steady slow speed, never head-on and never across the animal's path.
• Boats should not surround an animal, cut between members of a group, or place themselves between a mother and her calf.
• Only a small number of vessels should be with an animal at a time, and others should wait their turn rather than joining.
• Time with any one animal should be limited, and the boat should leave rather than following it indefinitely.
• Nobody should be in the water with them.

Now the deck view. A boat that is breaking those rules does so in ways that are obvious to a passenger who knows to look, and none of it requires expertise:

• The engine note rises when the whale is sighted instead of dropping. Approaching an animal is a slow manoeuvre. Accelerating towards one is not an approach.
• The boat aims at where the animal was, or at where the skipper thinks it will come up, rather than settling on a parallel course at a remove and waiting.
• It repositions repeatedly during the dive, running back and forth across the patch of sea where the whale went down.
• Crew move passengers to one side for a view, which tells you the boat is being placed for photographs rather than for the animal, and which is also a stability problem.
• Several boats form a rough ring and the whale surfaces inside it. This is the clearest single sign that the morning has gone wrong.
• The animal's own behaviour changes. Surface time gets shorter, the blows come closer together, direction changes sharply, and the whale disappears for a long period. A whale that was rolling calmly and then starts behaving evasively is telling you what the boats are doing to it.

The reason to describe this in such detail is that the enforcement gap is real. Once a fleet is over the horizon there is essentially nobody watching, and the only meaningful check on any skipper's behaviour is the reputation of the operator and the pressure of the people on board. Passengers who say early and clearly that they would rather see less from further away have more influence than they expect, because the crew's assumption is the opposite.

The chase produces a worse morning for you as well

The ethical argument against chasing tends to be made on the animal's behalf, which is correct and which also lets people file it as somebody else's problem. The self-interested argument is just as strong.

An undisturbed whale gives a boat a full sequence: several blows, a long roll, perhaps a tail, on a predictable heading, watched in quiet with the engine off. A harassed whale gives seconds. It surfaces briefly, changes course and goes down again, so passengers get a series of glimpses instead of an encounter. The total time an animal is visible from a well-behaved boat is usually greater, not smaller.

The photographs go the same way. Wash, spray, another vessel in the frame, a deck rolling in someone else's wake and an animal doing nothing but escaping do not add up to a picture. And the wash itself matters, because a stopped boat being rolled by the wake of four others is a reliable way to make half the passengers ill.

None of this argues for a distant, dull morning. It argues that patience is the technique that produces the good ones.

The questions that identify a decent operator before you pay

Booking is best done on shore in daylight, directly with the operator, ideally having walked down to the harbour the previous afternoon and looked at the boat. That alone filters out most of the trouble. Beyond it, the following questions are worth asking, and the manner of the answers tells you as much as the content.

• How many passengers will be on board, and what is the boat licensed for? A specific number in reply is a good sign. Vagueness is not.
• What do you do if three other boats are already with a whale? This is the single most revealing question on the list. The answer you want involves waiting at a distance or going to look for something else.
• How close do you get? An operator who boasts about closeness has told you everything. An operator who talks about keeping back has also told you everything.
• Is there a naturalist or guide on board, and what do they do the rest of the year? Someone who can talk about behaviour, other species and the ecology of the shelf changes a blank morning into an interesting one.
• What happens if the sea is too rough? Ask whether they cancel, who decides, and what is offered instead. An operator who says they always sail is not describing good service.
• Are there life jackets for everyone, including child sizes, and is there a safety briefing?
• Is there a toilet? On a five-hour trip this is not a trivial question, particularly for families.
• What happens to the rubbish? The answer should be that it comes back to shore.
• Which boat, by name, and where does it moor? This protects against being handed off to a different operator at the gate.

Reviews are useful if read the right way. Ignore the ones that only report whether whales were seen, since that is weather and luck. Look instead for how the boat behaved, whether it was overcrowded, whether the crew helped people who were ill, and whether anyone mentions racing. Those details are reproducible; the whales are not.

The guaranteed sighting, and the free second trip

Some operators advertise a guarantee. In practice it almost always means one of two things: a free second trip if nothing is seen, or a partial refund. Both sound reassuring and both are worth less than they appear.

Start with what "sighting" means, because the definition is the operator's and it is rarely written down. A distant blow counts. A pod of dolphins usually counts. A turtle has been known to count. Under most such offers, the circumstances in which a passenger can actually claim are far narrower than the promise implies, and the argument happens on a quay after five hours at sea, which is not where anyone wins.

Then the second trip. Most people visiting the south coast are there for a night or two on a moving itinerary. A free sailing tomorrow is worth nothing to someone who is being driven to Ella tomorrow, and the operator knows the redemption rate is low. It is a marketing cost, not a commitment.

The real objection is what a guarantee does to the incentives on the water. A skipper who has sold certainty has a reason to stay out beyond the point where the sea has got up, to push harder towards any reported animal, and to close on whatever is found rather than watch from a distance, because a boatload of people who saw nothing is a boatload of refunds. The promise that sounds like it protects the customer is in fact the mechanism that produces the chasing.

Nobody can guarantee a wild animal in open ocean. An operator who says as much, and describes instead how they search and how they behave when they find something, is telling the truth in a market where truth is a competitive disadvantage.

Overloading, litter and the rest of the friction

The other complaints about Mirissa are consistent enough to plan around.

Overloading is the most serious. Boats are sold on capacity, and some carry more people than they have places to sit, with passengers standing on cabin roofs and along the rails. That is unpleasant in a swell and it is a genuine stability issue when everybody surges to one side for a sighting, which is exactly what happens. Anyone who boards and finds a boat visibly packed beyond its seating has a difficult judgement to make in the dark, and the way to avoid making it is to have seen the boat and asked the numbers the day before.

Litter is the next. Food is often served on board in disposable packaging, and not all of it comes back. Passengers can decline the packaging, keep their own rubbish, and notice which crews collect it.

The harbour crush is unavoidable at the season's peak, with vans queuing, touts working the gate and boats rafted several deep. Arriving with time in hand converts it from stressful to merely noisy.

And then there is the plain fact that a rough morning is grim. Cold spray before sunrise, three hours of rolling, half the deck unwell and a horizon with nothing on it is a real possible outcome of this trip, and it is worth booking in that knowledge rather than in the expectation of the brochure.

The shipping lane, which is the larger problem

Worth knowing, because it puts the boats into proportion. The southern tip of Sri Lanka lies alongside one of the world's busiest maritime corridors, carrying traffic between the Malacca Strait and the Red Sea. Container ships and tankers pass in a near-continuous procession, and on a clear morning they are visible from the deck as a line of superstructures along the horizon.

The whales feed across that traffic. Collisions between large vessels and large whales happen here, and researchers working on this coast have argued for years that shifting the shipping lane a modest distance further south would reduce the risk substantially at very little cost to the ships. It is one of the rare conservation problems with a cheap and obvious answer, and it has been slow to move.

The two issues connect. A whale repeatedly displaced by boats is a whale spending energy and attention on the wrong thing in a piece of ocean where inattention is dangerous. Nobody should leave a whale-watching boat thinking the fleet is the only pressure on these animals, and nobody should conclude from the size of the shipping problem that how their own boat behaved did not matter.

What to take

• Something warm for the first hour. It is genuinely cool on deck before sunrise with the wind of the boat's passage on top of it, and people who dressed for a beach holiday are cold and miserable for the best part of the morning.
• Then sun protection, seriously applied. Once the sun is up there is no shade, the water reflects, and the breeze conceals how much burning is happening. A hat that will not blow off, sunglasses and long sleeves are more use than repeated cream.
• Shoes with grip, or bare feet. Wet timber and smooth soles are a bad combination on a moving deck.
• Water, and something plain to eat. Do not rely on what is provided.
• Motion sickness tablets, a bag and a spare shirt.
• Binoculars if available, which are worth more than any camera on this trip.
• A dry bag or a sealed pouch for phone, passport and money. Spray comes over the bow and salt finishes electronics permanently.

Trincomalee and Kalpitiya, the honest alternatives

Mirissa is the best known place to do this in Sri Lanka and it is not the only one, and for some travellers it is not the right one.

Trincomalee, in the other season

The east coast works on the opposite half of the year, roughly from May to September, when the south is closed by monsoon. The underlying geography is similar in kind: deep water within reach of the coast, and both blue and sperm whales known in the area, along with dolphins. The fleet is smaller and the pressure on the animals correspondingly lighter, which for many people is the deciding factor.

The trade-offs are real. The eastern season is shorter and less consistently established, there are fewer boats to choose between, and the same questions about behaviour need asking there. Anyone whose trip falls mid-year does not have to abandon the idea; it moves to the other side of the island.

Kalpitiya, for dolphins

On the north-western coast, Kalpitiya runs on roughly the same calendar as the south and is known chiefly for dolphins rather than whales, sometimes in very large aggregations. Anyone whose real wish is to watch dolphins at close range, rather than to see the largest animal on earth from a distance, will likely be happier there, and the trips are generally shorter and closer to shore.

The same caution applies with knobs on. Dolphin watching at Kalpitiya has its own history of boats driving into schools, and the choice of operator matters there for exactly the reasons it matters at Mirissa.

Who should probably skip it altogether

• Very small children. Three to five hours, no way off, sun, noise, motion and probably some sick adults nearby. Some operators set a minimum age; ask, and treat one that has thought about it as a good sign.
• Anyone with back or neck problems. A boat crossing a swell at speed slams, repeatedly, and the shocks go straight up the spine.
• Anyone with significantly limited mobility. Boarding is across other boats in the dark, decks are uneven and wet, and there are no adaptations of any kind.
• Anyone who must have the outcome. The people who enjoy this morning are the ones who booked a morning at sea and treated whales as the possible bonus.

Getting there, and the night before

Briefly, since the route pages cover the roads properly. Mirissa is about a hundred and fifty kilometres from Colombo and roughly two and a half hours on the expressway, which is what makes the whole thing feasible as part of a south-coast itinerary rather than an expedition.

• Bandaranaike International Airport to Mirissa — 195 km, about 180 minutes.
• Galle to Mirissa — 36 km, about 60 minutes.
• Matara to Mirissa — 11 km, about 20 minutes.
• Ella to Mirissa — 173 km, about 215 minutes.

The scheduling point is the only one that changes the visit itself. Boats go at six and they do not wait, so a same-day arrival from the airport does not work for a morning sailing, and the standard answer is to travel down the previous day and sleep within reach of the harbour. Staying in Mirissa itself makes the morning trivial. Coming from Galle means a start well before dawn on a coast road slower than its distance suggests, and anywhere beyond that is harder again.

A pickup before first light needs to be agreed when the car is booked, not mentioned the evening before. Drivers who work this coast expect the request, but a four o'clock start is an arrangement rather than an afterthought, and if a car is retained for the day it is worth settling whether it waits at the harbour, since the finishing time is not fixed. To arrange one, go to booking a car; the rest of the coast is covered in the other destination guides.

A sensible plan

1. Sleep in Mirissa or very close to it the night before, and go to bed early and sober. Everything else on this list is easier from there.
2. Walk down to the harbour the afternoon before and book face to face. Look at the boat, count the seats, ask the questions above, and get the boat's name.
3. Take the seasickness medication in good time, not at the gate, and eat something plain before boarding.
4. Arrive with time in hand. The gate is busy and boarding across rafted boats in the dark is not a thing to rush.
5. Sit low, near the middle, and outside for the whole trip.
6. Say early that you would rather watch from a distance and are happy to leave a crowded sighting. Crews assume the opposite and often prefer the quieter way of working.
7. Watch for the blow yourself. Passengers who search have a better morning than passengers who wait to be told.
8. Put the camera down after a couple of attempts and use your eyes, or borrow binoculars.
9. Keep a second morning free if the itinerary allows it. It is the only real insurance against weather and luck.

A morning off Mirissa is not a wildlife park with an entrance and a schedule. It is a search in open water, in a country where deep ocean happens to lie unusually close to a fishing harbour, and where that convenience has produced both the opportunity and the crowd. The whales are indifferent to which boat finds them. Everything else about the morning is decided by the vessel you chose the day before, and by whether its skipper is willing to stop the engine and wait.
