Summer Storms Forecast for 45 Provinces in Upper Thailand, 40% of Bangkok to See Rain

Thailand’s Meteorological Department warned on April 25 that summer storms will affect 45 provinces in upper Thailand, bringing thunderstorms, strong winds, hail, and possible heavy rain. The advisory includes Phuket, where scattered thunderstorms are expected, though the most severe weather is forecast for the north, northeast, central, and eastern regions.

Regional Weather Warnings and Impact

The north and northeast face a 40% chance of thunderstorms, with hail and strong gusts likely in provinces such as Chiang Mai, Lampang, Loei, and Khon Kaen. Minimum temperatures range from 21–28°C in the north and 23–27°C in the northeast, with highs up to 38°C.

Central and eastern provinces, including Nakhon Sawan and Chonburi, are also under a 40% thunderstorm risk, with similar temperature ranges. Bangkok and surrounding areas are forecast to see rain in 40% of the area, with lows of 26–28°C and highs reaching 37°C.

Southern and Marine Conditions

In southern Thailand, including Phuket, thunderstorms are expected in 10–20% of areas, mainly in Surat Thani, Krabi, and Trang. Minimum temperatures in the south range from 21–27°C, with highs up to 38°C. The Gulf of Thailand and Andaman Sea will see waves around 1 meter, rising higher during storms, prompting warnings for small boats to avoid affected zones.

Air Quality and Health Precautions

Northern and upper central regions are experiencing dust and haze levels above standards due to high concentrations of hot spots and limited air dispersion. Residents are advised to avoid outdoor exposure and use N95 masks for protection.
