Australia's darkest weekend of 2026 is here

This weekend, June 20-21, will be the darkest weekend of 2026 in Australia based on the amount of time between sunset and sunrise.

Winter solstice 2026: When and what is it?

The 2026 winter solstice will occur at about 6:24 pm AEST on Sunday, June 21, marking the moment Earth’s south pole reaches its maximum tilt away from the Sun. This means Sunday will be the shortest day of the year in the Southern Hemisphere, including Australia, based on the amount of time between sunrise and sunset.

The days surrounding the winter solstice have the fewest hours of daylight for the year, while the surrounding nights have the most hours of darkness. As a result, this weekend in Australia will have the shortest amount of daylight and the longest amount of darkness of any weekend in 2026.

There is a large range of daylengths across Australia on the date of the winter solstice, due to the large difference in latitude from the country’s north to south.

The winter solstice day lasts for about 11.5 hours in northern Australia, but only 9 hours in the country’s south. This means Darwin has almost 1.5 hours more daylight than Hobart.

Is the solstice the start of winter?

Winter officially begins in Australia on June 1 and ends on August 31. This is sometimes referred to as the ‘meteorological winter’ because it aligns well with the coldest three-month period of the year in Australia.

The winter solstice marks the start of the ‘astronomical winter’. While the solstice is not used to define the start of the season in Australia, it is recognised as the start of winter in some other countries, including the United States.

What happens after the winter solstice?

Following the date of the Southern Hemisphere’s 2026 winter solstice, days will start to get longer, and nights will get shorter across Australia. This trend of lengthening days and shortening nights will continue for around six months until the date of the Southern Hemisphere’s summer solstice in late December.

So, while it may feel like the days fly by this weekend, longer days are waiting on the other side of Sunday.
