NSW authorities have issued multiple warnings as parts of the state are set to be hit with above-average temperatures in coming days.
A high-pressure system over Central and Northern Australia this week will push the mercury up across parts of South Australia, moving in to inland NSW from Thursday.
It means those with weekend plans will need to take extra care and consider rescheduling, as certain regions are tipped to reach the mid-40Cs.
The Bureau of Meteorology is predicting those areas to include parts of the Northern Tablelands, Central West Slopes and Plains, Lower Western, and Upper Western Districts.
However, parts of Western Sydney are tipped to feel the heat, with Penrith on track to reach 42C on Saturday.
The Rural Fire Service (RFS) is warning of a heightened fire danger during the heatwave period, urging those visiting bushfire-prone areas to know the day’s Fire Danger Rating, and to make a Bushfire Action Plan.
Fire and Rescue NSW is likewise urging people to call triple-zero (000) immediately if they spot a fire.
NSW Health said those most vulnerable during a heatwave include people over 65, babies and young children, people with certain medical conditions, people who work outside, pregnant women, people who live alone or are socially isolated, and people who are homeless.
They’re urging people to watch out for signs of heat exhaustion and heat stroke.
And NSW Police are urging people to take it easy on the roads, with many people deciding to head to the beach, where they want people to keep an eye on kids near the water.
It also means fans of the Foo Fighters should take care in the heat, with the rock band playing at Accor Stadium on Saturday night.
With thousands expected to flock to the Sydney Olympic Park venue, hydration will be key, as night-time temperatures will only drop down to the low-20Cs at most.
It’s the same advice for anyone heading to see rapper 50 Cent on Saturday night performing nearby at Qudos Bank Arena — his second show after selling out Friday night’s performance at the same venue.
Those closer to the coast will be a little more fortunate, temperatures expected to peak at 31C on Friday around the Sydney CBD, and 35C on Saturday.
Parramatta is looking at a top of 35C Friday, and up to 40C on Sunday.
