Thailand is experiencing widespread heat, with some areas reaching extremely high temperatures, as of April 8, 2026. A low-pressure system covering upper Thailand, combined with weak southerly and southwesterly winds, is contributing to the conditions. Scattered thunderstorms with gusty winds are also expected, particularly in the North.
The southern region is also forecast to experience thunderstorms and gusty winds alongside daytime heat. Sea waves in the Gulf of Thailand and the Andaman Sea are expected to be around 1 meter, potentially higher during storms. Mariners are advised to avoid areas with thunderstorms.
Air quality is a concern in the North, Northeast, and upper Central regions, with accumulated dust and smoke exceeding standard levels. This represents attributed to a high density of hotspots in the North and surrounding areas, combined with limited air circulation. Residents are advised to avoid prolonged outdoor exposure and wear N95 masks for protection.
