Crickets chirping, barbecues sizzling, and the sun blazing—Australia’s summer is almost here, but what will the weather be like? The long-range forecast for December through February brings a mix of heat, storms, and uncertainty. While some regions brace for a scorcher, others are in for a wild ride with unpredictable rainfall.
Above-Average Temperatures and Unpredictable Rainfall
Australia is no stranger to extreme weather, and this summer is shaping up to be no different. Across most of the country, temperatures are expected to be above average. The heat will be especially intense in northwest and western Australia, as well as parts of southeastern South Australia, Victoria, and Tasmania. If you’re planning to escape the heat with a cool evening breeze, you might be disappointed—overnight temperatures are expected to be above average as well, particularly in northern Australia and Tasmania.
Interestingly, the rainfall forecast is a bit of a toss-up. The predictions have shifted since earlier forecasts, which were calling for a much wetter December. Now, the outlook is less certain. For parts of the west, below-average rainfall is expected, while eastern Australia’s forecast is more of a toss-up, with no clear indication if the rain will be above or below the norm. It’s a good reminder that, in Australia, you can never predict the weather with complete certainty—especially in summer.
Increased Fire Risk and Prolonged Heatwaves
With hot, dry air continuing to sweep across the country, the risk of bushfires is higher than usual. Authorities are particularly concerned about inland New South Wales, where the combination of a hot summer and vegetation growth from earlier floods could create dangerous fire conditions. Despite earlier forecasts predicting higher rainfall this year, things have changed, and the increased fuel load could lead to dangerous fire situations, especially in areas with prolonged heatwaves.
In Sydney, the heat has already broken records. October 2025 could go down as the hottest October on record for the city, with temperatures hitting a scorching 40°C in some areas, explains 7News. And if you thought that was intense, brace yourself for the summer ahead. With temperatures already breaking records, it’s clear that this summer will bring some serious heat.
Severe Weather Ahead: Storms, Cyclones, and More
As summer continues, severe storms are expected to roll across the country. The storm season in Sydney typically peaks in October and November, but experts predict that dramatic weather will continue throughout the summer and into early autumn. The most lightning-prone regions will be in the northern tropics, stretching from southeast Queensland down to central New South Wales. So, if you’re planning to spend time outdoors, be prepared for the occasional thunderstorm to disrupt your day.
And then there’s the tropical cyclone season. On average, three to four cyclones cross Australia’s coast each year, with nine or ten forming in the region. While it’s still too early to tell where the next storm might strike, it’s always wise to be prepared for the possibility of a cyclone, especially if you live in the northern or coastal parts of the country.
Stay Prepared, Stay Safe
Despite the uncertainty in the rainfall forecasts, one thing is certain: Australian summers are never boring. Whether it’s extreme heat, wild storms, or the looming threat of cyclones, the summer months bring a wide variety of weather. For those in fire-prone areas, this summer could be especially dangerous, so be sure to stay informed and have a plan in place.
Experts will continue to monitor the situation, adjusting forecasts as needed. But, in true Australian fashion, it’s always best to expect the unexpected. Prepare for the worst, hope for the best, and remember—summer is here to keep us on our toes. Whether you’re hitting the beach, camping in the bush, or just trying to keep cool in the city, this summer promises to be anything but predictable.
