Southeast Queensland swells in ‘severe heat wave’ driven by 90 pc humidity, says BOM

A short and sharp heat wave is expected to descend on southeastern Queensland today, with temperatures reaching 38 degrees Celsius in the interior of the region.

While this may not sound unusual for heat-adjusted Queenslanders, the Bureau of Meteorology (BOM) said there would be something unique for the next few days.

BOM forecast master Pieter Claassen said humidity levels would make it “particularly oppressive” for anyone spending time outdoors.

Dew point is a measure of the degree to which dew will occur, and Mr Claassen says dew points are “quite phenomenal” for south-east Queensland and can be compared to places like Cairns or Darwin at this time of year.

Claassen said the southeastern Queensland dew points were usually between 19 and 21 degrees on really humid days at this time of year.

“In terms of dew point, which is actually the best measure of humidity, they are rising up to the mid-20s,” he said.
