Frequently Asked Questions

Which Thai coast is rainy when the other is dry?

The Andaman coast (Phuket, Krabi) is wettest roughly May-October, while the Gulf coast (Koh Samui) sees its rainiest months around October-December.

Does it rain all day during Thailand's monsoon season?

Rarely — rain typically falls in shorter, intense afternoon bursts rather than continuous all-day downpours.

Is it cheaper to visit Thailand during monsoon season?

Yes, accommodation and flight prices generally drop noticeably during the rainier months due to lower demand.
