The live forecast above shows the weather expected across Australia, which can cause Christmas travel delays through heavy rain, damaging winds, or heat-related infrastructure issues.
How does the weather cause Christmas travel delays?
If you are flying or driving, the main weather risks around Christmas are tropical lows, severe thunderstorms, and heatwaves. A tropical low can bring days of heavy rain and flooding, which closes roads and delays flights. Severe thunderstorms produce hail and damaging winds that can ground planes and block highways. Heatwaves, common over the Christmas period, can cause tarmac buckling at airports and increase the risk of car breakdowns on long trips.
Which Australian cities are at risk?
Brisbane and Sydney face the highest risk of Christmas travel delays due to summer storms. If you are heading south, Melbourne and Adelaide can see cooler, showery weather that disrupts road travel. Check the latest conditions on our Melbourne weather and Sydney weather pages before you set out.
Will it rain on Christmas Day in Sydney?
Check the live forecast above. Sydney has about a 40% chance of rain on Christmas Day based on historical averages, but a severe storm can cause delays regardless of the total rainfall.
Can heat cause flight cancellations?
Yes. If temperatures exceed 40°C, aircraft take-off performance is reduced, which can lead to weight restrictions and cancellations. This is more common at airports like Perth and Adelaide.
How early should I check the weather before a Christmas trip?
Check the live forecast above 48 hours before departure. The Bureau of Meteorology issues a reliable outlook by that point, allowing you to plan for potential delays.
