Bangkok: Northern Thailand will experience warmer temperatures, while the South will have thunderstorms.
According to Thai News Agency, the Meteorological Department reports that upper Thailand is set to endure hotter weather, with some areas facing extreme heat, while the southern region will see scattered thunderstorms.
Temperatures are on the rise in upper Thailand, bringing hot weather during the day and extremely hot conditions in certain areas of the North and Central regions. Despite this, thunderstorms and gusty winds may occur in some areas due to a low-pressure system caused by heat covering upper Thailand. The southerly and southeasterly winds in these areas are weakening, prompting the public to take health precautions against the rising temperatures. Residents are advised to avoid prolonged outdoor activities and to remain cautious of potential dangers from thunderstorms and strong winds.
In the southern region, scattered thunderstorms are expected due to easterly and southeasterly winds affecting the Gulf of Thailand, the southern region, and the Andaman Sea. Furthermore, between April 28 and May 1, 2026, upper Thailand is predicted to experience summer storms characterized by thunderstorms, strong winds, and, in some areas, hail and possible lightning strikes. These storms will initially impact the Northeast, North, and East regions, eventually affecting the Central region, including Bangkok and its surrounding areas, due to another high-pressure system or cold air mass from China moving over the South China Sea.
Meanwhile, air pollution levels in the northern region continue to exceed standards in some areas because of a high density of hotspots that surpass the area's ventilation capacity. The public is urged to avoid outdoor activities and wear an N95 mask for safety when outside.
