PATTAYA, Thailand – The Thai Meteorological Department has warned that summer storms are expected to affect upper Thailand from March 3–6, beginning in the Northeast before extending to the East, Central region, Bangkok and surrounding areas, and later the North.
For Pattaya and Thailand’s eastern seaboard, conditions over the next 24 hours are forecast to remain hot and hazy during the daytime, with a chance of isolated thunderstorms in some areas.
Located in Chonburi Province, Pattaya is expected to see daytime temperatures ranging between 33–38°C, with overnight lows around 24–28°C. Southerly winds of 10–30 km/h are forecast, while sea conditions are generally calm, with waves below one meter. However, in areas experiencing thunderstorms, waves could rise above one meter.
The Meteorological Department explains that upper Thailand is currently under the influence of a heat-induced low-pressure system, while southerly and southwesterly winds continue to bring moisture into the region. This combination creates unstable conditions that can trigger localized thunderstorms, particularly during the late afternoon or evening hours. Residents and visitors are advised to take precautions against sudden downpours, gusty winds and lightning.
From March 3 onward, a high-pressure system from China is expected to move southward and interact with the hot air mass already covering upper Thailand. This clash of air systems may lead to typical summer storm activity, including thunderstorms, strong winds, isolated hail, heavy rainfall in some locations and occasional lightning. While the Northeast is forecast to experience the first impact, eastern provinces, including areas near Pattaya, may feel effects in the days that follow.
Although seas off Pattaya remain relatively calm, boat operators in the Gulf of Thailand are advised to exercise caution and avoid navigating through areas where thunderstorms develop, as wave heights can increase suddenly. Beachgoers are also encouraged to remain alert, particularly in open areas during unstable weather conditions.
Air quality across upper Thailand remains at low to moderate levels due to moderate ventilation and the likelihood of scattered rainfall in some areas.
Despite the heat, Pattaya’s coastal location may provide some relief from inland temperatures, but officials continue to recommend staying hydrated and limiting prolonged exposure to direct sunlight during peak afternoon hours. As March progresses, residents can expect typical late dry-season weather, with hot days occasionally interrupted by brief but sometimes intense summer storms.
