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 Singapore, Singapore
Singapore's equatorial climate can combine persistent humidity, intense solar exposure and limited overnight relief. Government heat-stress guidance uses WBGT for prolonged outdoor activity, making the hourly trend especially relevant for work, training and recreation.
Forecasts describe outdoor conditions, not an individual's medical risk. Workload, duration, shade, clothing, acclimatization and health can change the appropriate decision.
