Wet Bulb Globe Thermometer

The Wet Bulb Globe Temperature (WBGT) index is a single “temperature” that takes into
account the effects of air temperature, humidity, sun, heat reflected from the ground,
and wind all at the same time. This is more accurate than simply looking at temperature
or humidity alone. WBGT values above 25 begin to feel uncomfortable and may affect
health and performance.

Based on this, a curtailment of competitions for IMGA will be implemented
at >30

Decisions on implementing this limit rests with the competition Ground Jury.
In borderline conditions WBGT reading will be checked at the start of each session.
Once under the limit at the start of a heat, that heat will be completed.
