The heat policy is doing nothing. At 11am today 16 January 2013 these are the weather conditions at the Australian Open Tennis(1):
Ambient = 38 degrees C. WBGT = 32 degrees C.
At WBGT 26 degrees C Sports Medicine Australia say to “limit intensity, take more breaks”.
At 30C WBGT Sports Medicine Australia say to “Consider postponement to a cooler part of the day or cancellation”.
The US OSHA rules say to have 25% rest at 26C and at 30C to have 75% rest. It’s above that already at 11am. (3)
But the tennis goes on.
The heat policy is pointless. The average maximum temperature in Melbourne in January is 26 degrees C. If the policy does nothing in record breaking heat, what is it’s purpose?
