Koh Tao – Best time to go

Best time to visit Koh Tao

The weather in Koh Tao can be split into three main seasons:  dry season (between December and February), hot season (between March and August) and rainy season (between September and November). Temperatures remain steady across the year and the seasons are determined by the amount of rainfall. As most visitors to the island will be interested in diving, July and August offer the most ideal conditions. Clear visibility under the water and cooler temperatures above the water.
