Post-season — prices falling after the travel period, beaches and attractions quieter.
April in Sri Lanka is generally manageable, but with 9 rain days it's not a reliably sunny month. Better conditions can be found in January, February, March, July, August, and December.
Daytime highs reach 32°C (90°F) with a daily average of 29°C (84°F) — nights stay warm at 25°C (77°F). Peaks reach around 33°C (91°F), the coldest nights around 23°C (73°F). The sun shines an average of 8 hours per day; there are 9 rain days with 175 mm (6.9 in) total. The water is a warm 31°C (88°F) — perfect for snorkelling and swimming.
Sun protection, a hat, and plenty of water are essential at these temperatures. Plan activities for early morning or evening.
Shoulder season: rain arrives on the west coast. The east coast — Arugam Bay, Trincomalee — starts its best season for surfing and swimming.
