Where these numbers come from
WeatherAPI supplies the forecast. HeatGuard calculates heat-index risk and models WBGT from forecast temperature, humidity and a daytime solar allowance. Modeled WBGT is not an on-site globe-thermometer reading.
Local planning context
Planning for heat in Bangkok, Thailand
Bangkok's persistent humidity, urban heat and strong daytime sun can produce demanding conditions for outdoor work. Thailand's occupational guidance uses WBGT, workload and exposure time when evaluating workplace heat.
Forecasts describe outdoor conditions, not an individual's medical risk. Workload, duration, shade, clothing, acclimatization and health can change the appropriate decision.
