What you gain in August
- ↑Cheapest accommodation rates alongside May: extraordinary value even at boutique old-city properties
- ↑Temples like Wat Chedi Luang completely uncrowded — wander without the tour group shuffle
- ↑Evening food scene in the old city unaffected: Khao Soi, sai ua, and khao kha moo at their authentic best
What you sacrifice
- ↓175mm: the wettest month — expect daily heavy rain and occasional flooding in lower-lying streets
- ↓Doi Inthanon summit often completely cloud-covered; the drive up less rewarding
- ↓High humidity at 80% is relentless — air-conditioning becomes a non-negotiable requirement
