What to do

In the morning, if the sea allows, a trip to Phi Phi; direct beach access at Maya Bay was restricted until 30 September 2026 per some offers, so check with the operator. Otherwise, spa, Thai cooking, old town and shopping malls: Phuket when it rains. See also Phuket in August and Phuket in October.

Prices and booking

Hotel prices drop clearly and there are few people in Patong and Kata. Pick a pool and free cancellation.
