The Thai Meteorological Department (TMD) forecasts that daytime temperatures will remain high over the next few weeks as summer intensifies. This alert comes as the country braces for continued heat, raising concerns about public health and safety.

Last year, Thailand experienced 21 heat-related fatalities during a summer where the heat index hit dangerous levels. The TMD has categorized heat index risk bands, ranging from "caution" at 27.0–32.9C to "extremely dangerous" at 52C or higher. Currently, humidity levels could elevate the heat index in some regions, compounding the situation. Authorities emphasize the need for caution as this year's temperatures are projected to surpass those of last year, especially in the North, Northeast, and Central regions.
Experts highlight the potential for summer storms to provide temporary relief in some upper regions of Thailand, with strong winds and isolated hail forecasted for this week. However, these weather conditions may not significantly lower the heat index, which accounts for combined temperature and humidity effects. Medical professionals urge residents to remain vigilant and hydrated to combat heatstroke risks.
Looking forward, temperatures are expected to rise from Tuesday to Sunday according to the TMD. Communities have been advised to take preventive measures such as avoiding outdoor activities during peak heat hours and increasing water consumption. Public safety campaigns and initiatives are likely to be intensified in the coming weeks to mitigate the impact of the severe heat, reported Bangkok Post.
