Quick answer
February is one of the best months for whale watching in Sri Lanka. Boats leave Mirissa harbour around 6 to 7am and head to deep water south of Dondra Head, where blue whales are seen on many trips. Sperm whales, Bryde's whales, spinner dolphins and flying fish are also common. Trips last four to five hours, and the sea is usually calm in February. Choose an operator that follows responsible guidelines. Trincomalee's whale season, on the east coast, is later, from about March to August.

The whale season and why February is good
Blue whales and other species feed in the deep water south of Sri Lanka, where the continental shelf drops steeply close to shore. The south coast whale season runs roughly from December to April, when the sea is calm enough for boats to head out.
February is in the heart of this season. The sea is usually at its calmest, sightings are frequent and the weather is dry and sunny.
On the east coast, off Trincomalee, the whale season runs later, from about March to August, when that sea is calm.
Scientists believe the blue whales off southern Sri Lanka may be part of a population that stays in the northern Indian Ocean all year, moving between feeding areas rather than making long migrations. That is one reason sightings off Mirissa are so reliable during the calm months.
- →South coast: December to April.
- →February: calm seas, frequent sightings.
- →East coast: March to August.
How a trip works
Most trips leave Mirissa harbour between 6 and 7am. Boats head south for about an hour to the deep water near the shipping lanes, where the crew and spotters look for blows, the spray whales exhale when they surface.
Once whales are found, boats slow and observe from a distance. Trips usually last four to five hours, returning around midday. Breakfast and water are often included.
Seasickness is possible even on calm days, as boats spend time drifting. Take tablets before boarding if you are prone to it, and sit on deck in fresh air.
Most boats have a covered deck for shade and an open deck for viewing. Bring cash for tips if the crew work hard to find whales.
- →Depart 6 to 7am.
- →Four to five hours.
- →Take seasickness tablets if needed.
What you might see
Blue whales are the main attraction. They can be more than 25 metres long, and seeing one surface and dive, showing its tail, is unforgettable. Sightings are common in February but never guaranteed.
Sperm whales, Bryde's whales and occasionally fin whales and orcas are also seen. Spinner dolphins often ride the bow waves, and flying fish skim across the surface.
Sea turtles are sometimes spotted on the way out or back.
Photographing whales takes patience. A blue whale usually surfaces several times to breathe before a long dive, raising its tail as it goes down. Watching for the blow, keeping the camera ready and using a fast shutter speed gives the best chance of capturing the moment.

Choosing a responsible operator
Whale watching boats are supposed to keep a safe distance, approach slowly and not chase, surround or cut off whales. In practice, some operators crowd the animals, especially when many boats are out.
Choose operators that follow the guidelines, limit the number of passengers and have trained crew. Ask about their practices before booking and read recent reviews.
Larger boats are more stable, which helps with seasickness, while smaller boats can feel closer to the action.
Planning your trip
Stay in Mirissa, Weligama or nearby to make the early start easy. Book a few days ahead in February, or a week ahead during half-term.
Bring sunscreen, a hat, sunglasses, a light layer for the early morning, water and a camera with a zoom lens.
The planners at Lankan Stays & Trails usually schedule whale watching on the first morning of a south coast stay in February, leaving time for a second attempt if the sea is rough.

- →Book a few days ahead.
- →Bring sun protection and a zoom lens.
Frequently asked questions
Is February a good month for whale watching in Sri Lanka?
Yes, it is one of the best. February is in the heart of the Mirissa whale season, with calm seas and frequent sightings of blue whales, sperm whales and dolphins. The weather is dry and sunny. Sightings are common but never guaranteed.
Where is the best whale watching in Sri Lanka in February?
Mirissa, on the south coast. Boats head to deep water south of Dondra Head, where blue whales feed. Trincomalee, on the east coast, has a later season, from about March to August, when its sea is calm.
How long is a whale watching trip?
Usually four to five hours, leaving around 6 to 7am and returning around midday. Boats spend about an hour reaching the deep water and then search for whales. Breakfast and water are often included.
Will I get seasick whale watching?
Possibly, even on calm February days, as boats spend time drifting. Take seasickness tablets before boarding if you are prone to it, sit on deck in fresh air and look at the horizon. Larger boats are more stable.
Are whale sightings guaranteed?
No. Sightings are very common in February, but whales are wild animals. Some operators offer a free second trip if no whales are seen. Ask about this when booking. February gives some of the best odds of the year.
How do I choose a responsible whale watching operator?
Choose operators that keep a safe distance, approach slowly, do not chase or surround whales, limit passenger numbers and have trained crew. Ask about their practices and read recent reviews before booking.
Is whale watching suitable for children?
It can be, for older children who cope with early starts and several hours on a boat. Younger children may find the trip long, and seasickness is a risk. Choose a larger, more stable boat, bring snacks and water, and take seasickness precautions for the whole family.
