Chiang Rai rainy season & dry season
Is August wet or dry?
Thailand’s southwest monsoon generally brings rain from mid-May to mid-October. The southern east coast also receives northeast-monsoon rain, so Koh Samui and Phuket do not share one wet/dry-season calendar. The 2024–2025 average for August is 28 wet days.
2024–2025 wet-day averages, not long-term season boundaries. Wet days do not mean all-day rain.
Packing for rainy and dry periods
For rainy periods, bring a light rain jacket, a waterproof pouch and quick-dry clothes. In drier months, pack sunscreen and a hat, plus a compact umbrella for showers. For beach trips, check the boat operator’s weather and cancellation notices.
