Warmer weather returns in earnest across the southern states by 15 November 2027, 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.
The week containing Monday 15 November 2027 is counted from this date under the standard week-numbering convention used on this page, with weeks running Monday to Sunday rather than Sunday to Saturday. This convention affects rostering, payroll cycles and any planning done in weekly blocks across Australian workplaces that pay staff or schedule shifts on a weekly basis.
A public holiday that falls on a Monday or a Friday produces a three-day weekend without using any annual leave, which is why long-weekend planning around 15 November 2027 depends on which day of the week the nearest public holiday falls on. A midweek holiday delivers no such automatic extension, though many workers bridge it with a single day of leave.
