Weather
The wettest month overall. The Andaman gets the tail of the monsoon, the Gulf is transitioning, and Bangkok can flood in heavy years. Rain comes in long afternoon bursts rather than all day.
The turn
Around the third week the rain eases and the Andaman starts to calm. The last ten days of October are often excellent and still priced as low season — the best-value window of the autumn.
How to plan
Keep one flexible day, choose hotels with indoor space, and favour cities and the north over fixed beach itineraries. Travel insurance that covers weather delays is worth it.
