Overview
- City data show the heat index has held at a critical 42–52°C range since April 1, with Bangkok hardest hit.
- The Bangkok Metropolitan Administration is running more than 300 free cooling centers in libraries, schools, clinics, and government offices.
- Officials say the network focuses on low-income neighborhoods without home air conditioning, with a goal that most residents can reach a site within 15 minutes.
- Health authorities urge people to avoid direct sun during midday and to watch for dizziness, exhaustion, or heat cramps.
- Relative humidity above 70 percent, a delayed monsoon, and weak winds trap hot, humid air between buildings, making it feel far hotter than the air temperature.
