Best Time to Visit the Islands of Thailand

The optimal time to visit Thailand‘s islands depends on the climate and crowd differences throughout the year. 

November to April marks the dry season with sunny skies, warmth, and calm seas, ideal for beach activities and ocean exploration. Conversely, the period from May to October is the rainy season, characterized by frequent downpours. 

Notably, the Christmas holidays and days leading to the Thai New Year in April observe the most tourist influx. For those who prefer a more relaxed experience, the shoulder months of November or late April can offer more secluded spots and slightly cooler weather. 

Unique experiences like Thailand’s renowned Full Moon Party on Koh Pha-ngan introduce an exciting atmosphere. It is typically held on the night of every full moon, but note that it does not occur during certain Buddhist holidays, such as Buddhist Lent. The schedule is based on the lunar calendar, so the date of each Full Moon Party varies from month to month.
