The optimal travel time for Koh Tao is hardly dependent on the weather. The island has warm temperatures all year round, which are quite bearable due to the near sea climate. Travellers can therefore plan their holiday entirely according to their own priorities. The summer months of July and August (with restrictions until September) are the main travel season, when the prices for accommodation and travel are seasonally increasing. The winter months of December through March are also a popular time to visit Koh Tao. Especially in the summer season early booking is necessary.
