Temperatures in Sydney’s west are expected to soar above 40 degrees Celsius today, while the city’s east should be spared thanks to a sea breeze.
Penrith is forecast to reach 43C today, while the city will only reach 35 degrees.
“Yesterday some very hot air was sitting over inland New South Wales [with] temperatures reaching 43 degrees, now that air is coming over Western Sydney today,” Bureau of Meteorology duty forecaster Rob Taggart said.
“The places near the coastal Sydney areas, they’ll be spared because sea breezes will come in and prevent that really hot air from coming in to the eastern suburbs.”
A total fire ban has been declared for the Greater Sydney and Illawarra-Shoalhaven regions.
Mr Taggart said a cool change would come through Sydney about midnight offering some relief tomorrow, but the rest of the state would not be so lucky.
“The northern inland parts of the state will remain very hot over the coming seven days with temperatures in the high 30s or even the 40s … most of the time,” he said.
“The north-west and the central-west [will be] particularly affected with temperatures increasing up into the mid-40s early next week and Tuesday in particular looks to be the hottest for western districts.”
Stay inside and check on elderly relatives
Dr Ben Scalley from NSW Health advised people to stay inside, drink lots of fluid and check on their elderly relatives and friends.
He said dehydration and heat stroke were common health problems during heatwaves, but there were also increased incidents of other illnesses.
“Heat has a lot of effects on the body in terms of stressing the body and we even see increases in effects like heart attacks during these periods,” he said.
“It’s really important that people take precautions to protect their own health.”
