Trincomalee's deep submarine canyon and seasonal upwelling produce high productivity that attracts large baleen whales.
Blue whales (the Northern Indian Ocean form often referred to in literature as B. m. indica) are regularly sighted from boats off Trincomalee during the calm eastern-season months, with highest encounter rates in the local dry season months.
