Wonderful!!! we did a round trip (with group). We were there for 15 days, we were advised against August because of the rainy season. But well, nothing as changeable as the weather shall we say. Only on the last day we had some wind and rain at the end of the day, but otherwise all days were dry and (nice and) warm.
LaurensSeptember in Sri Lanka was pleasant. The days were sunny and warm, ideal for active recreation. There were times when it rained, mostly in the evening, but that only added to the tropical experience. Nice place!
TijnThere are rain showers, but they are short and cool. Ideal for a sunny winter vacation.
Sven BonekampThere were a few tropical showers, but otherwise it was mostly sunny and warm; an inviting contrast to the rugged Netherlands.
BramThe general climate was warm and sunny, but with little rain. Pleasant weather for relaxing on the beach. Not perfect, but nice.
Daan van der MeerIt was mostly sunny, although there was some rain. The temperature was pleasant, around 30 degrees.
ChristiaanThe temperature was high, but not stifling. From time to time there was an unpredictable downpour, which brought some changes to the vacation.
TijnAlternating sun and rain, but more rain than expected. Being hot and humid, comfortable clothing was required. Wind relaxed. Overall not bad for relaxing on the beach or exploring nature.
WesselsWarm incredibly
