Phuket weather by month


Source: Meteorological data for Phuket is based on weather statistics collected during the 30-year period 1991 to 2020 by the Thai Meteorological Department at the closest weather station: Phuket International Airport (HKT), situated in the north of Phuket Island. Additional climate data is sourced from the United States National Oceanic and Atmospheric Administration (NOAA).

Advice on the best time to visit a particular destination is based on average local weather statistics, when the weather conditions are generally better than at other times of the year. We consider high and low temperatures, risk of rain (and thunderstorms, etc.), amount of sunshine and sea temperature. For general outdoor activities we favour clear, rainless days with a temperature range between 18°C (64°F) and 27°C (80°F); and for hot-weather activities we favour clear, rainless days with a temperature range between 24°C (75°F) and 32°C (89°F). Often, the best times to visit correspond to high season and therefore involve higher prices.
