Queensland state schools remain open and students are not sent home during periods of excessive heat or heat wave conditions. Heatwave conditions are specifically when excessively high temperatures combine with high humidity levels and are sustained over a number of days. That means, although the predicted maximum temperature for a region may be in the mid-to-high 30s, unless this coincides with high humidity and lasts for a few days, it is considered 'hot' rather than a 'heat wave'.
People are most at risk during extreme heat conditions when the temperatures reach about 5 degrees Celsius above the average for sustained periods of time. In South East Queensland, the Bureau of Meteorology will issue advice to the Department of Health when apparent temperatures are forecast to exceed 35 in Brisbane and 37 in Amberley, for at least two consecutive days.
Heat-related conditions cover a wide range of symptoms ranging from swelling of hands and feet, prickly heat occurring in acclimatised people and heat cramps, through to heat exhaustion, to the more severe and potentially fatal heatstroke. See Department of Health Heat-related illness fact sheet.
Managing schools during excessive heat or heat wave conditions:
Factors to consider when cancelling or postponing a sporting event include but are not limited to:
If the ambient temperature is between 31 and 35 degrees Celsius and the relative humidity is over 30 per cent, planned vigorous, sustained activity may 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 25 per cent, planned vigorous, sustained activity may be postponed to a cooler part of the day or even cancelled.
