Well how's this for an early taste of Summer!
Sydney we're set to swelter though the hottest September day in four years, with the mercury set to soar to 32 degrees. It'll be 12 degrees above the average.
"It'll warm up very quickly in western suburbs once that wind picks up. The wind blowing from the north west, is going to raise pollen levels, raise dust and also the fire danger today" Brett Dutschke from Weatherzone said.
"For large parts of Sydney it looks like being the warmest September day in four years, but the cooler change will be arriving this evening, tomorrow is going to be at least 15 degrees cooler than today" Dutschke said.
Fire authorities aren't taking any chances, with a total fire ban in place for Greater Sydney. It's one of four regions across the state where no fires are allowed to be lit today, including the hunter, north coast and north-western areas.
It comes as fire fighters have spent the night at a blaze at Beacon Hill, on the Northern Beaches, after a grass fire broke out yesterday morning.
It has been contained with no homes under threat and will continue to be patrolled ahead of worsening conditions later today.
