Welcome to your seasonal guide to Sri Lanka. The island's two monsoon systems mean each region has its own dry and wet months. The West Coast is best from December to March for beaches, water sports and coastal trips. The south coast has the same December to March dry season, ideal for clear skies, beaches, galfort and whale watching. The east coast is dry from April to September, giving better weather for seaside plans. The Central Highlands stay cooler with mixed rain, making them comfortable most of the year. The North and Northeast are dry from May to September, the opposite of the South and West. The cultural triangle works year-round, with some months better for outdoor visits. If you're moving between regions, match your dates to each area's best weather window. Wherever you go – coasts, highlands, north or heritage sites – pick the season that suits your route. Enjoy your trip!
