Phuket Weather and Best Times to Visit
Phuket’s climate is governed by the Andaman Sea and the southwest monsoon — a pattern that creates one of the world’s most celebrated high seasons but also one of the more dramatic rainy seasons in Southeast Asia.
Understanding this pattern is essential for planning your relocation and timing your arrival.
Phuket’s Climate Seasons
High Season — November to April
The Andaman coast’s high season runs from November through April, when the southwest monsoon retreats and northeast winds bring calm seas, low humidity, and near-perfect beach conditions. The water is clear turquoise, visibility for diving reaches 30 meters at prime sites. Temperatures sit comfortably between 25-32 degrees C.
November through April: Phuket at its finest — exceptional beach conditions, clear water, world-class dive season fully open
Monsoon Season — June to September
The southwest monsoon arrives in June and reaches its peak in July and August. The Andaman Sea becomes rough, making beach swimming inadvisable on west coast beaches. The Similans close completely from May 15 through October 15. Rainfall is heavy and sustained. The island is significantly quieter; rents can be negotiated.
June to September: monsoon season — reduced beach and water access but authentic island life at significantly lower costs
Shoulder Season — May and October
The transitional months offer value propositions for expats. The island is significantly less crowded, prices drop, and the weather alternates between clear sunny periods and rain showers.
Best Time to Relocate to Phuket
October or November arrival is ideal — the monsoon is ending, the island is transitioning to high season, and you can experience the best of Phuket weather during your establishing months.
