Warmer weather returns in earnest across the southern states by 13 November 2026, 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.
Friday 13 November 2026 is the last working day of the standard Monday-to-Friday week, the fifth and final working day before the weekend begins. A public holiday landing on this day of the week joins directly onto the Saturday and Sunday that follow it, forming a three-day weekend without using any annual leave.
The week number shown for 13 November 2026 counts full weeks from the start of 2026, a figure used in payroll cycles, rostering and any planning done in weekly or fortnightly blocks rather than by calendar month. Businesses running fortnightly pay runs rely on this figure to track which of the two alternating pay weeks a date falls in.
