Heatwave conditions will intensify across large parts of central and eastern Australia on Wednesday, as temperatures soar in Sydney.
This will be Sydney's hottest day in a sultry week, as northwesterly winds carry hot air across the Basin. The mercury will be around the mid-twenties at the start of the day and could reach 38 degrees in the city and over 40 in the west during the afternoon.
Sea breezes will be limited to eastern parts of Sydney during the afternoon due to the strength of the offshore wind flow. As a result, most suburbs will stay hot until a blustery southerly change arrives at around 5-7pm. The change should drop temperatures by 5-10 degrees in an hour or two for most areas.
Outside Sydney, the hot air mass will also be felt across multiple states and territories on Wednesday. Oodnadatta in South Australia, Thargomindah in Queensland and Walgett in New South Wales are all forecast to reach 44 degrees, while Bourke and Birdsville could hit 45.
Tomorrow's southerly change will mainly bring relief to aras east of the Great Dividing Range, causing inland areas to bake until at least Friday.
Tips on staying healthy during heatwaves include:
- Stay hydrated
- Eat smaller, cool meals
- Keep yourself in a cool environment
- Avoid strenuous exercise
- Do not leave children or pets inside vehicles
- Keep in touch with sick or elderly friends and family
- Ensure you have enough food and water to avoid going out in the heat
- Consider your options in case of power outages
