According to the live forecast above, Australia’s summer (December 2025 – February 2026) is expected to bring above-average temperatures across most of the country, with rainfall near or slightly below the long-term median for many regions. This outlook is driven by a weak La Niña-like pattern in the Pacific and record-warm sea surface temperatures off northern Australia.
What are the temperature and rainfall ranges for summer?
Maximum temperatures are likely to be 1–2°C above the 1991–2020 average over most of the mainland, with the highest anomalies in the interior and southwest. Rainfall totals are expected to be 10–30% below normal in the southeast and southwest, while the Top End and parts of Queensland may see near-median falls. The 2026 weather predictions australia from the Bureau of Meteorology show a 60–70% chance of exceeding median summer rainfall only for the northern tropics.
