Koh Tao Weather
Koh is an unique island in that it can be visited all year round. There is always find a bay where the sea is calm so you can dive or snorkel somewhere on the island throughout the year.
We do have a short rainy season from November to the end of December, but even at that time the weather can be great.
January to March is know as the dry season as the weather generally warms up to hot steamy days, with some rain coming in fits and starts.
Most people avoid Thailand during May and June, as they mistakenly think it’s the monsoon season. The monsoon at that time of the year is on the west coast of Thailand effecting islands such as Phuket, Phi Phi, Koh Lanta etc., while on the east side of Thailand we can get some of the best conditions of the year.
