THERE is unlikely to be much relief from the hot days and humid nights heating up the Hunter until a cool change arrives on the weekend, the Bureau of Meteorology (BoM) says.
Most of NSW is set to swelter in “severe heatwave conditions” this week, with the day time maximum temperatures for some inland parts of the Hunter Region expected to reach more than 10 degrees above average for this time of year, according to the BoM.
But the impact is likely to be “less dramatic” on the coast thanks to some north-easterly winds.
Temperatures are expected to soar to about 44 degrees in Cessnock and Singleton on Friday, with temperatures expected to stretch into the high-20s and low-30s on the coast.
Anita Pyne, Bureau of Meteorology NSW/ACT meteorologist, said hot air from central Australia was moving into the south and far west parts of NSW.
“As this week progresses, that hot air is going to continue to progress further north, so that much of NSW will be in severe heatwave conditions by the end of the week,” she said.
A “heatwave” is a period of at least three days of above-average conditions.
There would be no “significant relief” from the heat until a southerly change on the weekend.
“We are predicting high temperatures for much of NSW, particularly around western Sydney, the Hunter Valley and a lot of highly populated areas,” Ms Pyne said. “This is very serious, as heatwaves actually claim the most lives of any severe weather event within Australia. It particularly affects elderly and sick people. Have a plan to beat the heat, drink plenty of water, and be sensible.”
