Autumn begins on 1 March, and by 13 March 2026 the southern states see shorter days and cooler mornings settling in. The northern wet season continues through March, with cyclone activity still active ahead of its April end, while the south moves out of its summer bushfire peak as the season turns over into the cooler months.
Traffic volumes, flight bookings and getaway trips peak on Friday afternoons across Australian cities as the working week ends. Friday 13 March 2026 falls on this day of the week, at the close of its standard five-day working stretch, marking the start of the weekend for the standard Monday-to-Friday workforce.
The quarter containing 13 March 2026 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
