The weather in Samui in February is probably the best in terms of living the tropical island life. A mere 30mm of rainfall is expected to fall in the evenings or nights of just five days, leaving the days sunny and dry and average temperatures at around 27°C/81°F. Humidity is also low and continuing to get even lower, averaging between 63% and 90%. The sea is great for divers and snorkelers, being perfectly calm and pleasantly warm at 27°C/81°F. With such ideal beach conditions, February is naturally quite a popular month for visitors, making this firmly a part of the high season. The Chinese New Year period is particularly busy, especially at the island’s shrines and temples.
