Posted 09.00 Wednesday 31 December,2025
*USING GEMINI AI AND BOM DATA AND INFORMATION
It’s looking like a classic Sydney summer night for the 2025 celebrations. Whether you’re heading to the harbor for the 9:00 PM family fireworks or staying for the midnight show, conditions are looking favorable.
Tonight’s Outlook (Wednesday, Dec 31)
-
Evening (6:00 PM – 9:00 PM): Expect temperatures to hover around 22°C to 24°C. It will be quite humid, but a light sea breeze should keep it from feeling too stifling for those in the crowd.
-
Midnight: For the main event, the temperature will drop to a comfortable 20°C. Perfect for being outdoors without needing a heavy jacket.
-
Rain Chance: Very low. There is currently a less than 10% chance of rain, meaning the fireworks should go off under clear or partly cloudy skies.
-
Wind: Light northeasterly winds at 15–20 km/h. This is ideal for clearing the smoke between the two fireworks displays without causing safety issues for the pyrotechnics.
