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 Fukuoka, Japan

Fukuoka residents already encounter WBGT through Japan's national heat-illness warning system. Use this hourly forecast-based estimate for planning, then compare it with the Ministry of the Environment's local WBGT observation and alert before strenuous outdoor activity.

Forecasts describe outdoor conditions, not an individual's medical risk. Workload, duration, shade, clothing, acclimatization and health can change the appropriate decision.
