Marine biologist, side-by-side breakdown. MIRISSA (south coast): season NOVEMBER to APRIL, primary species BLUE WHALES + Bryde's whales + spinner dolphin superpods, sighting rate ~75-85% in peak season, boat trip 3-5 hours, water usually calm-to-moderate, downside is BOAT DENSITY - 15-30 boats regularly circle the same sighting which stresses the whales. TRINCOMALEE (east coast): season MARCH to AUGUST, species BLUE WHALES + SPERM WHALES (rare elsewhere in Sri Lanka), sighting rate 60-75%, trip 3-5 hours, water can be rougher (open Indian Ocean, wind), MUCH fewer boats (5-10 on a peak day), and sperm whale sightings are genuinely bucket-list for whale enthusiasts. KALPITIYA (west coast): season NOVEMBER to APRIL, primary species SPINNER DOLPHIN SUPERPODS (500-1000+ dolphins together, world-class), occasional blue whale and sperm whale, sighting rate for dolphins 90%+ / whales lower ~30-40%, trip 3-4 hours, water usually calm. For a serious whale enthusiast: Trincomalee for sperm + solitude, Mirissa for reliable blues, Kalpitiya for the dolphin spectacle.

PRACTICAL prep. Sea-sickness is real even in calm conditions; take dimenhydrinate/Sturgeron the night before AND 1 hour before boarding. Bring: sunscreen SPF 50+, wide hat that ties on (wind), sunglasses, water, a warm layer for the wind, a plastic bag for phone protection. Prime departure is 6-6:30 AM (calmest seas, best light for photography). Book at least 1 buffer day into your itinerary in case weather cancels the trip - it happens a few times per season everywhere.

Trincomalee in April for the sperm whales it is. Booking with an ethical operator, buffer day scheduled. Merci!

ETHICAL operator selection matters more than location. The gold standard rules: (1) Approach whales at low speed and never from directly ahead. (2) Minimum 100m distance maintained. (3) Maximum 3-4 boats at one sighting. (4) No swimming with cetaceans. (5) No engine-revving to move whales. Reference operators (not exhaustive): Raja and the Whales in Mirissa (widely considered the ethical benchmark on the south coast, run by conservation-aligned owners), some certified operators in Trinco through the Navy-permitted list, and the smaller Kalpitiya lagoon-based dolphin operators. Booking through your hotel doesn't guarantee ethics - ask directly about the 5 rules above and don't book if they can't answer clearly.
