PATTAYA, Thailand – Intense summer heat is set to dominate Pattaya and much of Thailand throughout the Songkran holiday, with temperatures expected to remain high from April 11–16, prompting health warnings for residents and tourists.
The upper parts of the country, including the eastern seaboard, will experience hot to very hot conditions during the day, with hazy skies caused by heat-induced low pressure. In Pattaya, the afternoon sun is expected to be particularly strong, raising concerns for those spending extended periods outdoors during water celebrations.
Authorities are advising people to stay hydrated, avoid prolonged exposure to direct sunlight, and limit outdoor activities during peak afternoon hours, especially along crowded beachfront and festival areas.
While the weather will remain mostly dry in Pattaya early in the period, isolated thunderstorms may develop in some areas, bringing brief heavy rain, gusty winds, and the risk of lightning.
Conditions are expected to shift slightly around April 16–17, when a high-pressure system from China begins influencing the region. This could trigger summer storms across parts of eastern Thailand, including Pattaya, with the possibility of strong winds, thunderstorms, and even isolated hail.
Meanwhile, air quality concerns persist in parts of Thailand, with dust and haze levels exceeding safe standards in the north and upper regions, although Pattaya is less severely affected compared to inland provinces.
At sea, conditions remain relatively calm, but boat operators are still advised to avoid sailing during storm activity.
With large crowds expected for Songkran festivities, officials are urging both locals and visitors to remain cautious—not just of the celebrations, but of the weather itself.
