Sri Lanka is subject to two monsoons. Then the rainy season starts on the North and East Coast, the dry season starts on the South and West Coast & vise versa. This means Sri Lanka is a year around destination, and there is always a ‘right’ season somewhere in the island.
High Season (Dec–Mar)
The Hill Country plus west- and south-coast beaches are busiest – and driest.
The Maha monsoon season (October to January) keeps the East, North and ancient cities wet.
Shoulder (Apr & Sep–Nov)
April and September offer the best odds for good weather countrywide.
A good time to wander without a set schedule.
Low Season (May–Aug)
The weather in the North and East is best.
The Yala monsoon season (May to August) brings rain to the south and west coasts plus the Hill Country.
