Best time to visit Sri Lanka

The best time to visit Sri Lanka is either Jan-Apr or July-Sep for the best odds of good weather countrywide. The weather in Sri Lanka is somewhat complicated given that it has two separate monsoon seasons affecting different parts of the country.

The best time for exploring the hiking trails around Ella is between Dec-Mar when the Hill Country is driest. The shoulder season of April and Sep-Nov is a decent time to visit while the Yala monsoon season of May-Aug brings rain to the Hill Country.

The best time to visit the south and west coasts is Jan-Mar when the region is mostly sunny. With April comes the monsoon season. Jun-Sep are the wettest months but are still sunny. In November, the weather turns hot and humid but it’s still a good time to visit especially for Diwali celebrations.
