Sydney will sweat through a scorching day on Wednesday, with parts of the city to exceed 40 degrees as firefighters warn of “very high” fire danger for the region.
The Bureau of Meteorology predicts the inner city will reach 36 degrees, while Bondi will have a top of 34, Penrith and Richmond will have a maximum of 42. Campbelltown and Liverpool will reach 38 degrees.
Angus McLean-Smith, a meteorologist with Weatherzone, said the hottest temperatures are expected in the late morning, driven by north-westerly winds.
A southerly change will then sweep across the city from about midday, with temperatures dropping quickly and rain and thunderstorms possible for the afternoon.
In the west, the cool change is due from about 1pm.
“There’s a southerly coming through, a big southerly change in the afternoon,” Mr McLean-Smith said. “That’s going to cool across the board.”
The NSW Rural Fire Service has declared a total fire ban for the Greater Sydney, Greater Hunter and North Western regions for all of Wednesday, with hot and windy conditions bringing “very high” fire danger for Sydney and “severe” fire danger for the other two regions.
The Greater Sydney region includes the Blue Mountains and Central Coast, while the Greater Hunter encompasses Cessnock, Dungog, Lake Macquarie, Maitland, Muswellbrook, Newcastle, Port Stephens, Singleton and the Upper Hunter, and the North Western region includes the Moree Plains, Narrabri, Walgett and Warrumbungle.
After Wednesday, the heat will temporarily taper off, before the mercury rises again in time for Christmas Eve. Christmas Day itself is due to be mild and cloudy, with late rain, southerly winds and possible thunderstorms.
On Tuesday, NSW Ambulance received 55 calls for heat-related illnesses between midnight and 2pm, including dizziness, nausea, fainting, heat exposure and one child who was locked in a car.
Most of those feeling the heat were aged over 60, with the weather exacerbating pre-existing conditions like heart problems, diabetes or chemotherapy.
Temperatures soared away from the coast, with Badgerys Creek, Camden, Campbelltown, Horsley Park, Penrith and Richmond all reaching or exceeding 40 degrees.
The heat affected track infrastructure on the Blue Mountains train line, causing some delays.
A NSW Ambulance spokeswoman urged people to take care in the heat, reserve their activity to the coolest part of the day, avoid drinking tea, coffee and alcohol, and keep up with their medications.
“Try to stay out of the direct sun – this is particularly important for the elderly and very young,” the spokeswoman said. “Drink plenty of water and if outdoors, carry a water bottle.
“If you know of family, friends or neighbours who are isolated or alone, check on their well-being to ensure they are OK.”
