The weather in Samui in December sees a rapid return to blue skies and sunshine after the extremes of November’s monsoon rains. There will still be some rainy days, particularly early in the month, but you can expect only 150mm of precipitation dropped over nine days. Temperatures remain at their winter lows of about 27°C/81°F and humidity is steady at 68% to 92%. Surfers can still enjoy good waves as the northerly winds stir up the 27°C/81°F seas. However, by about Christmas time and in the run-up to the New Year celebrations, you will generally find ideal beach weather across the island.
