Weather in Thailand

Thailand has a 'dry' season, when there is hardly any rain, from late October to May/June, after which temperatures are rising up to 35-40C in April/May. Thereafter, rainy season begins, and temperatures will drop, while at the same time humidity increases. Showers usually appear in the afternoon and can sometimes be fierce, a great tropical shower! In August/September prolonged rains can set in with dull grey skies.
Beaches in Southern Thailand have two weather systems, bringing tropical rains at different times of the year. This allows you to find all year round beaches where life is good.

Best time to visit Thailand
The best time to plan your tour in Thailand is from November to March, there is a lot of sunshine and blue skies and temperatures are pleasant, it's even cool in the North. At the coast  seas are calm and clear.
But you can perfectly visit Thailand at other times of the year, taking a tropical thunderstorm into account once in a while! The advantage is that it is less crowded and rates are lower. The seas, however, have a different quality and can be rough. Visibility for diving and snorkeling can be reduced. 

As there are two weather systems in the South, you can find a great beach to stay at in almost every time of year. 
From January to September, beaches on the east coast have the greatest chance of sunny and dry weather (Koh Samui, Koh Phangan).
From October to April, destinations such as Koh Chang, Phuket, Krabi, Koh Phi Phi and Koh Lanta are the best.
