Your capital city New Year’s Eve forecasts

Source Weatherzone Tue 30 Dec 2025

With 2026 almost upon us, here are the New Year's Eve and New Year’s Day forecasts for each Australian capital city. Melbourne Melbourne’s maximums have been on a see-saw this week, with a pair of unseasonably cool 17-degree days on Christmas Day and Boxing Day, then 35°C on Monday, December 29. The final day of 2025 will be cool again with a maximum around 19°C. That means that New Year’s Eve will be cool with southerly winds if you’re out and about, but the good news is there’s only a very slight chance of a shower. Expect a slightly warmer day with a high near 23°C to ring in the new year on Thursday, January 1. Sydney After a run of searing mid-December heat (including a high of 42.2°C on December 19), Sydney has seen a cool spell since Christmas, including a maximum of just 18.7°C on Boxing Day. The final day of 2025 should reach 26°C, with mild and cloudy conditions prevailing as the sun sets. There's the chance of a shower and a slight chance of a thunderstorm, but with luck, any rain will be brief enough not to dampen the spirits of those attending the world's most spectacular New Year’s Eve fireworks display.

Brisbane The flooding rains in the north are a world away from southeast Queensland at the moment, and Brisbane might just be the pick of the capitals on New Year’s Eve, with clear, warm conditions after a Wednesday maximum of 32°C. New Year’s Day looks cloudier with a chance of showers and a maximum of 30°C. Canberra The national capital has had an unseasonably chilly string of nights, with a week of single-digit minimums from December 24 to 30 inclusive (December’s average minimum is 12°C). But Canberra is at last warming up, and after a maximum around 29°C for the final day of the year, it should be a pleasant New Year’s Eve in terms of temperature, with a minimum of 14°C expected the following morning. The only issue is the chance of rain. Showers and even a thunderstorm are likely in the afternoon and early evening of December 31, but with luck, they’ll be gone by dark so the New Year’s Eve fireworks aren’t spoiled.

While the December 31 high of 19°C won't exactly be warm, most locals won’t argue after a run of four days from December 24 to 27 when Hobart’s maximum failed to top 16.5°C. The good news is it should be dry for the evening festivities.  New Year’s Day should be a touch warmer with a top of 21°C and mostly dry conditions. Adelaide After almost hitting 40°C on December 29, cool southeasterly winds will restrict the maximum to around 25°C in the SA capital on the final two days of 2025. While relatively cool by local summer standards, New Year’s Eve skies should be clear, making for pleasant conditions outdoors. New Year’s Day looks a little warmer with an expected top of 29°C.

After a December 31 maximum of 35°C, light winds and clear skies should make for a perfect evening out. The new year kicks off with almost identical conditions, with another two days of expected 35-degree maximums on January 1 and 2. Darwin There's virtually always the chance of an evening shower or thunderstorm at this time of year in the Top End, and New Year’s Eve 2025/26 in Darwin will be no different. Darwin’s rainfall for December 2025 is currently tracking at about 50mm above the monthly average of 254.9mm, with rain recorded across 19 days. Yet December 28 and 29 were rain-free. While there’s a chance that dry conditions could continue through to the end of 2025, moisture from the remnants of TC Hayley (currently a severe tropical cyclone off the coastline of northwest WA) could revamp the monsoon. Expect maximums around 33°C on both December 31 and January 1. - Weatherzone © Weatherzone 2025
