The weather in Samui in November is best enjoyed by surfers. This is the peak season for wave riders, with the 27°C/81°F seas seeing metre-high breaks off most of the popular beaches, created by strong northerly winds. This makes celebrating Loy Krathong quite an adventure, to say the least! Enjoying a beach holiday is still possible as there are some sunny days, particularly early in the month. Temperatures are at quite a pleasant 27°C/81°F and humidity is around 70% to 94%. Furthermore, this being the low season, hotels and flights are at their cheapest. However, the risk of rain is at its highest during November, with 430mm of rain expected across 15 days, often in very heavy monsoon storms.
