Off-season — lowest travel prices with still acceptable climate.
November in Thailand (Koh Samui) offers acceptable conditions — but it's not among the top travel months. Those looking for ideal weather should visit in February, March, April, and August.
Daytime highs reach 31°C with a daily average of 28°C — nights stay warm at 25°C. With 5 sunshine hours per day and 16 rain days (474 mm), this is one of the cloudier months. The water is a warm 29°C — perfect for snorkelling and swimming.
An umbrella or waterproof jacket is essential. On rainy days, plan indoor activities like museums and markets.
