Note: Calculation of the sun WBGT has been suppressed for this hour because the approximation used is not valid at these times.

The shade WBGT is calculated for an environment shaded from direct (and strong reflected) solar radiation and where surfaces are not significantly hotter or colder than the indicated air temperature.

* The calculation of AT requires an observation of temperature, humidity, and wind. If any of these are unavailable, the AT field is left blank.

The WBGT values displayed here should be used in conjunction with guidelines provided by Sports Medicine Australia (SMA).

Sports Medicine Australia may also provide additional regional guidelines. The AT values displayed here are the Steadman Apparent Temperatures measured in the shade. The Apparent Temperature is an estimation of what the temperature "feels like" to an appropriately dressed adult. Direct exposure to the afternoon sun would add as much as 8C to the AT.
