Best time to visit Phuket

The best time to visit Phuket is generally January to March and September to November, when humidity and rainfall are at their lowest, which is what actually varies here. Daytime temperatures in that window sit near 86°F (30°C), with rain on about 18 days a month. For the same question asked the other way round, see where else is warm in January.

Pack for Phuket with light clothing for the warm months, proper waterproofs rather than an umbrella - wet days are the norm here and moisture-wicking fabrics for the humidity. April nights average 78°F (26°C), so evenings rarely match the afternoons.
