Thailand Phuket Weather in March — Climate Guide
March in Phuket is very-high
March is very-high for Phuket.
March is the start of Phuket's hot-dry transition — beach conditions still excellent, rainfall still minimal (5 rainy days, 50mm), but daytime heat climbs and UV peaks at 11. The shoulder week before Songkran (April 13-15) is the year's best value-for-quality window: dry weather, low crowds, hotels at 70% of February pricing.
Phi Phi + Similan still operating at full capacity with excellent visibility. James Bond Island day trips at peak conditions. Sunset photography at Promthep Cape gets the cleanest light of the year (low humidity haze).
