What is WBGT?
Wet Bulb Globe Temperature combines air temperature, moisture, wind, and radiant heat. For a coach, the useful difference is simple: WBGT accounts for the sun and airflow around outdoor activity, not just the temperature shown in a weather app.
Forecast versus field measurement
A forecast WBGT estimates conditions across a weather grid. An approved on-site instrument measures the local environment where activity is happening. Turf, shade, buildings, and wind can create meaningful differences.
Forecast WBGT is an estimate intended for advance planning. Actual field conditions may differ. Follow your governing organization’s policy and use an approved on-site WBGT device when required.
How coaches can use it
Check the hourly trend before practice, plan a workable time window, then use the measurement method required by your school or governing organization. PracticeCast automatically matches the address to its state guidance.
