Unawatuna in August

November through April gives you Unawatuna at its best — calm seas, minimal rain, and that perfect beach weather that makes you forget about checking the forecast. December and January bring crowds and higher prices, but also the most reliable sunshine. March and April heat up but stay dry, plus you'll have more space on the beach. The monsoon hits May through October, turning the sea rough and the skies grey. Some places close entirely during the worst months (June-August). But here's the thing about shoulder season — September and October can surprise you with clear days and empty beaches, if you don't mind the risk of rain. Just avoid July completely unless you enjoy swimming in washing machine conditions.
