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 Birmingham, AL
Birmingham can combine high humidity with warm mornings and evenings. Humidity may keep the heat index elevated even when air temperature alone looks manageable, so compare the full hourly window before choosing a start time.
Forecasts describe outdoor conditions, not an individual's medical risk. Workload, duration, shade, clothing, acclimatization and health can change the appropriate decision.
