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 Hong Kong, Hong Kong
Hong Kong's humid subtropical conditions can sustain heat strain during outdoor work, hiking and sport. Labour Department guidance explains WBGT as a combined heat-stress measure; on-site exposure and current official warnings should guide workplace decisions.
Forecasts describe outdoor conditions, not an individual's medical risk. Workload, duration, shade, clothing, acclimatization and health can change the appropriate decision.
