Sperm whale watching works in a handful of places, for one geological reason: the animal hunts in deep water, so you can only reach it where a canyon runs close to the coast. Kaikōura, Andenes and the Azorean islands all have exactly that, which is why all three sail through most of the year while other destinations manage a season. Trips start at $51.59 on Pico; prices on this page are checked regularly.
What you are looking at
NOAA describes the sperm whale as the largest of the toothed whales, 40 feet for females and 52 feet for males, 15 to 45 tons, living up to 60 years. The head takes up about a third of the body and holds the spermaceti organ — an oil sac that helps focus sound, and the reason the species was hunted from 1800 to 1987. The skin behind the head is often visibly wrinkled, the flippers are small paddles, the flukes are triangular, and the dorsal fin is a low rounded hump rather than a fin. It is the only living cetacean with a single blowhole set asymmetrically on the left of the crown, which is why the blow angles forward and left instead of straight up.
Everything about the trip is shaped by the dive. NOAA says hunting dives routinely reach 2,000 feet and can last 45 minutes; the whale then rests at the surface for several minutes before going down again. So a sperm whale tour is a listening exercise punctuated by a few minutes of whale. Crews use hydrophones to pick up the clicking of a hunting animal, position the boat where it should come up, and wait. When the surface interval ends, the back arches, the blow shortens, and the flukes come up — the single image everyone on board is waiting for.

Sperm whales are watched where a canyon comes close to land, so the season follows the boats and the weather more than the animals. Kaikōura and Andenes sail through the year; the Azores and Iceland stop when the sea does.

Where and when
Kaikōura is the benchmark. Whale Watch Kaikoura, the Māori-owned operator on that coast, states that sperm whales are year-round residents and that tours typically see one to two whales. It publishes a success rate of over 90% and, unusually, a written consequence if the trip fails: a refund of 80% of the fare. Tours run all year at three set times, with a fourth departure added in the southern summer. See New Zealand.
Andenes, at the northern tip of Vesterålen, is the European equivalent. Whalesafari runs trips throughout the year from Andenes, with a main summer season from May to mid-September, and works the Bleik canyon just offshore. In mid-October to late January its attention shifts north to Skjervøy and Alta for the herring-season orcas and humpbacks — a different trip entirely. See Norway.
The Azores put sperm whales on the doorstep of Lajes do Pico, Horta and Ponta Delgada. Espaço Talassa, working the Pico grounds since the late 1980s, notes that sperm whales can be seen just a few miles from the coast and sometimes closer than three miles, and lists them among the species it observes most often; its published sightings tables run from March through October, which is the practical season. The clifftop vigia lookouts, inherited from the whaling years, still direct boats to animals the crews cannot see. See the Azores.
West Iceland gets a smaller version of the same thing. IceWhale reports sperm whales most commonly seen on tours from west Iceland in late spring and early summer, roughly April/May to August/September, and notes that the animals around Iceland are males — which fits NOAA's description of adult bulls migrating into temperate water while females and calves stay in the tropics. See Iceland.
Two more coasts belong on the list without belonging at the top of it: Madeira, where sperm whales turn up year-round alongside pilot whales and bottlenose dolphins, and Mauritius and Madagascar, where sperm whales are watched off the west coast of Mauritius. Both are places to take a sperm whale as a good outcome rather than a plan.

There is a real trade-off here and it is not about price. The RIB gets you low and close and turns fast when a whale surfaces behind you; the catamaran gets you there dry and lets you stand up in a swell that would have you gripping a rope on the RIB. Canyon water is open ocean in all three destinations, and a sperm whale trip involves more waiting than a humpback trip does. Decide honestly which of those two matters more to you.

Read any sighting promise closely. Kaikōura's is the clearest published example on this page — an explicit "no", followed by an 80% refund if the tour finds nothing, and a definition of "whale" taken from New Zealand's Marine Mammals Protection Regulations so that a pilot whale or an orca counts. Elsewhere, a "guarantee" more often means a free second trip on a later sailing, which is worth something only if you are still in town. Ask before you pay, and check the exact wording on the listing.
Listening, not looking
On a humpback trip the crew scan for blows. On a sperm whale trip they scan and listen. Sperm whales click almost continuously while hunting — a regular, metronomic sound that carries for miles underwater — so a crew with a hydrophone can tell whether an animal is below them, roughly how far away it is, and when it stopped clicking, which is the signal that it has caught something and will start its ascent.
That is why the boat often stops in apparently empty water and everyone is asked to be quiet. Some Azorean and Norwegian boats put the hydrophone on the speakers so you hear the clicks yourself; it is the closest most passengers get to understanding what the animal is doing while out of sight. The Azores add a second, older technique: the vigias, shore lookouts on high ground who spot blows from land and radio the position to the boats.
What a day costs
The Azores are the cheapest way to see this species: $51.59 for a two-and-a-half-hour trip from Lajes do Pico, $80.25 for the three-hour São Miguel and Pico boats, $88.77 for the research-style expedition from Horta on Faial. Kaikōura is $99.99 for a three-and-a-half-hour cruise, or $217.12 as a full day from Christchurch, which is the sensible way to do it if you are not staying on the coast. Norway is the expensive option, and the Andenes trips are priced in NOK on the operator's own site rather than in the feed.
Two practical notes. Sperm whale destinations cancel for weather more than most, so build a spare morning into the plan rather than a spare hour. And take the earliest departure of the day if you can — flat water makes a low blow visible at a distance that a chopped-up afternoon sea will hide completely.
Where sperm whales are a bonus, not a plan
Madeira sails year-round out of Funchal, where resident pilot whales are the dependable animal and sperm whales the occasional one. Mauritius has a similar profile off the west coast near Tamarin. Sri Lanka's east coast turns up sperm whales during the Trincomalee season, on trips sold as blue-whale tours.
None of these are bad trips. They are simply trips where the sperm whale is the good day rather than the expected one, which is a different thing to book against — and the reason the four rows in the season table above are the ones worth planning a journey around.

Check Kaikōura dates from $98Questions people ask
How big is a sperm whale?
NOAA gives 40 feet for females and 52 feet for males, and 15 to 45 tons — the largest of the toothed whales. The head accounts for about a third of body length.
How deep and how long do they dive?
NOAA says hunting dives routinely reach 2,000 feet and can last 45 minutes, after which the whale recovers at the surface for several minutes. IceWhale puts the maximum submersion at up to an hour.
Why is Kaikōura so reliable?
Whale Watch Kaikoura states that sperm whales are year-round residents there and that it typically sees one to two whales per tour. A submarine canyon runs close inshore, so the boats reach hunting depth quickly.
Does anyone guarantee a sighting?
No one guarantees the whale. Whale Watch Kaikoura answers its own question — 'Am I guaranteed to see a whale? NO' — then commits to refunding 80% of the fare if the tour sees none, and cites over a 90% success rate.
Are all sperm whales in one place the same sex?
Often, yes. NOAA notes adult males make long migrations into temperate waters while females and young stay in tropical waters year-round; IceWhale states that the sperm whales around Iceland are males.
What will I actually see?
A low, bushy blow angled forward and to the left — the blowhole sits asymmetrically on the left of the head — a long wrinkled back, a small rounded dorsal hump, then triangular flukes lifting for the dive.
Why do the Azores boats stop and listen?
Crews use hydrophones to hear the clicks of a hunting whale, and in the Azores the clifftop vigia lookouts also direct boats from land. Both are ways of finding a whale that spends most of its time out of sight.
