Phuket in September One of the rainiest months of the year. The sky is dark and the sea is rough, so a beach stay is hard to count on. If you do swim, stay in shallow water and only on days without red flags.
It was a hot month: 32°C by day and 25°C after dark. Rain came so often (17 days on average) that dry stretches were short and worth using. Year to year it swung widely, from 10 rain days in 2019 to 23 in 2020.
With 30 days above 30°C on average, most of the month felt like high summer. Rain days averaged 22 mm each, so when it rained it rained properly.

What to pack Loose linen or quick-dry cotton, a wide-brimmed hat and sunscreen were the basics. A water bottle stayed in the bag, and midday plans moved indoors.
Rain came often, so a hooded waterproof jacket beats an umbrella. Choose shoes that dry quickly.
