Warmer weather returns in earnest across the southern states by 9 November 2028, with the first genuinely hot days of the season arriving during November, ahead of summer's official start on 1 December and the cyclone season that runs through the tropical north until April.
Thursday sits one working day ahead of the weekend, making it the point in the week where plans for Friday, Saturday and Sunday commonly get finalised. 9 November 2028 falls on this day of the week, the second-to-last working day before the standard Monday-to-Friday week comes to a close and the weekend takes over.
The working-day count on this page excludes both weekend days and any public holiday declared for the state selected, so the same date in 2028 can show a different total depending on which state's calendar applies to 9 November. Interstate businesses need to check more than one state's list before setting a national deadline.
