Thailand Phuket Weather in January — Climate Guide
January in Phuket is very-high
January is very-high for Phuket.
January is the single best month to visit Phuket — driest, coolest tropical highs, calmest Andaman seas, and crystal-clear visibility for Phi Phi and Similan snorkeling. The trade-off is maximum hotel pricing and the year's biggest tourist crush — book accommodation 8-12 weeks ahead.
Beach conditions are ideal: Patong, Kata, Karon, and Surin all have calm water and consistent green flags. Phi Phi day tours run with 95% reliability (rare cancellations). Similan Islands snorkeling/diving (open Nov-Apr) is at peak visibility (25-30m). Sunset at Promthep Cape happens at 18:10 — arrive by 17:00 for parking.
