Trincomalee or Mirissa?
The two coasts have opposite calm seasons. Mirissa trips usually run from about November to April, when the south coast is calmer. Trincomalee's calmer season is roughly March to October. Choose the coast that matches your travel dates.
| Trincomalee (east) | Mirissa (south) | |
|---|---|---|
| Calmer season | Roughly Mar–Oct | Roughly Nov–Apr |
| Distance to deep water | Short — a submarine canyon runs close to shore | A longer run offshore |
How to recognise a blue whale
Look for a tall, column-shaped blow, a very long mottled blue-grey back, a tiny dorsal fin set far back, and sometimes the tail flukes lifted before a deep dive.
Other whales you may see
Sperm whales are also seen off Trincomalee. They have a square head and a bushy blow angled forward. Other species are recorded less often.
Watching blue whales responsibly
We stop well back, never chase or cut across a whale's path, and leave when it moves away. Read our code.
