Quick answer: The best time to visit Phuket is the dry season, November to April — sunshine, calm seas and the liveliest beaches (peak is December to February). The monsoon (May to October) is greener, cheaper and quieter, with daily rain. It’s warm (28–33°C) all year.

Seasons explained
The dry season (Nov–Apr) has the calmest seas and best beach weather — ideal for island-hopping to Phi Phi and the Similans. The green/monsoon season (May–Oct) sees short, heavy downpours rather than all-day rain, with lush scenery and the year’s lowest prices — but watch for strong currents and red-flag beach warnings.
What to pack
Light, breathable clothing, strong sunscreen and a hat year-round; add a compact rain jacket and quick-dry shoes for the green season.
