WBGT Calculator (Estimated)

What is WBGT?

The Wet Bulb Globe Temperature (WBGT) is the most specific temperature index used to determine heat-stress exposure for humans. Unlike the Heat Index, WBGT takes into account angle of sunlight and wind speed (in the full formula).

Note: This tool uses the Bureau of Meteorology (BOM) approximation which estimates WBGT from temperature and humidity assuming full sunshine and light wind. For critical safety, use a physical WBGT meter.
