Bangkok has experienced 19 consecutive days of hazardous heat index levels, with temperatures and humidity combining to create conditions that pose serious risks to public health. Since April 1, the heat index in the city has consistently remained within the "danger" range, measured between 42 and 51.9 degrees Celsius, according to the Bangkok Metropolitan Administration (BMA).

The heat index differs from standard temperature readings by incorporating humidity to reflect how hot it actually feels, which has significant implications for heat-related illnesses. Officials have urged residents to minimize prolonged outdoor activities, particularly during the hottest hours of the afternoon, and to remain vigilant for symptoms such as fatigue, dizziness, muscle cramps, rashes, and signs of heatstroke. Vulnerable populations, including the elderly and those with preexisting health conditions, have been advised to seek prompt medical attention if symptoms arise.

In addition to the extreme heat, the Meteorological Department has forecast summer storms to continue through April 25. The city is expected to experience intermittent thunderstorms accompanied by gusty winds, with storm activity predicted for today and again from April 23 to 25. Authorities have highlighted the need for caution as shifting weather patterns could compound health risks and impact safety.

As Bangkok navigates these challenging weather conditions, officials continue to monitor the situation closely, emphasizing public awareness and preparedness to mitigate the potential effects of the prolonged heat wave and incoming storms.
