Best time of year to visit Trincomalee?

The best time to visit Trincomalee is between May and September, when the East Coast has its dry season, and the ocean stays calm and clear.

At the same time, the southern and western parts of Sri Lanka get hit by monsoon rains during these months. Trincomalee, meanwhile, gets brilliant sunshine, flat seas, and strong underwater clarity, making it a good window for snorkelling at Pigeon Island, diving, and watching whale migration, which moves toward the eastern seaboard during the northern hemisphere summer.
