Andaman Sea, Khao Sok

Thailand’s west coast has three defined seasons. From November to March, many consider conditions to be at their best with a cooling wind keeping the sky-high summer temperatures at bay and making the daytime more comfortable (avg daily temp: 26°C -32°C). Thanks to the breeze, the humidity levels are lower than later in the year.

From March through to May the temperatures rise (avg daily temp: 30°C-36°C) as the cooling winds depart and the humidity rises.
Come late May, monsoonal weather will usually have arrived, which is expected to last through to October. Peak rainfall levels are usually experienced between mid-September and mid-October. Outside of these months, the rain will often come in a short, heavy downpour, usually in the afternoon.

Khao Sok National Park in southern Thailand follows the same weather patterns as the Andaman Sea coastline, experiencing most rainfall between May and October, although being one of the wettest areas of the country, rain showers can be expected year round. Wet season is actually a good time of year to visit the National Park as average temperatures are a comfortable 25-26°C, the rainforest is green & lush, and there is more chance of spotting wildlife.
