Thailand in October: Weather, What to Expect & Where to Go
October is the changeover. The Andaman side dries out gradually through the month and is usually pleasant by Halloween. The Gulf side reverses — Samui and Phangan start their wet season, peaking in November. Centre and north are clearing out fast.

Nakhon Ratchasima (Korat)
Drying out fast. Khao Yai's waterfalls are still strong but trails are firming up — one of the best windows of the year for a long weekend in the park.

Events & festivals in October
Ok Phansa (end of Buddhist Lent)
End of the three-month rains retreat. Long-boat races on the Chao Phraya in Bangkok and across Isaan — a great time to be on the water.
Is October a good time to visit Thailand?
October is the gamble month. Late October is often a sweet spot — Andaman recovering, north cooling, no crowds yet. Earlier in the month, expect rain everywhere.
