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 Oklahoma City, OK
Oklahoma City heat risk can change quickly with humidity, cloud cover and the timing of a weather system. Use the hourly values rather than a single daily high, and reassess when the activity lasts into a warmer part of the day.
Forecasts describe outdoor conditions, not an individual's medical risk. Workload, duration, shade, clothing, acclimatization and health can change the appropriate decision.
