Strong sunshine forecast to push Chiang Mai temperatures to 35°C

Temperatures to rise under warm air and strong sunshine

From October 20 to 21, temperatures in Thailand are expected to rise as strong sunshine combines with warm air. Skies are mostly clear, and sunshine is warming the surface. Aloft, warm air of +18°C or higher near 1,500 m is spreading widely from the South China Sea and continues to warm areas near the surface. This pattern is expected to continue.

Outlook for major locations

Strong sunshine and warm air are expected to persist during this period. Chiang Mai is forecast to reach 35°C on both the 20th and 21st, with humidity of 53% to 55%. Bangkok is forecast to reach 33°C, while Phuket, where sunshine will be weaker, is expected to see 31–32°C; neither is expected to reach 35°C.

Please limit outdoor activities during the day as much as possible. Take precautions against the heat, including drinking water regularly and improving ventilation indoors.
