In the northeast and the southwest, the coasts cut across the stratification of crystalline rocks, cliffs, bays, and offshore islands, creating one of the world's best natural harbors at Trincomalee on the northeastern coast and a smaller rock harbor at Galle on the southwestern coast. First Inter-monsoon Season (March – April)– Thunderstorm type rainfall with warm and uncomfortable conditions Southwest-Monsoon Season (May – September)– The warm season is eased away by the windy weather during this particular monsoon season.
