The BSRA season is in the autumn and winter months and therefore reaching high temperatures to the extent that it compromises competition is very unlikely.
Guidelines from Education Queensland:
If the ambient temperature is between 31 and 35 degrees Celsius and the relative humidity is over 50 per cent, there is a high to very high risk of heat illness. Planned vigorous, sustained physical activity should be limited in intensity or duration to less than 60 minutes per session.
If the ambient temperature is over 36 degrees Celsius and the relative humidity is over 30 per cent, there is an extreme risk of heat illness. Planned vigorous, sustained physical activity should be postponed to a cooler part of the day or even cancelled.
Our regattas are conducted with a Regatta Committee. Rowing Queensland is part of this committee, their heat policy is here Rowing Queensland Heat Policy
