Traveller notes on Ko Tao in October
Other months in Ko Tao
Ko Tao's forum calls March a good window as the seas calm after the rainy season — flat water and great visibility for diving, with only occasional cloudy days and the odd rain shower rather than a washout. Regulars flag the humidity as climbing as the hot season sets in, though it's not yet the peak heat of April-June.
