Best Time to Visit Phuket: Month by Month Guide
Phuket's Two Seasons
Phuket has a tropical monsoon climate with two main seasons: the dry season (November to April) and the wet season (May to October). The island is warm year round, with temperatures typically between 25 and 33 degrees Celsius. The main variable is rainfall and sea conditions, which significantly affect what activities are available and how crowded the island is.
