Check the live forecast above before heading out in Ultimo today. The inner-city suburb gets a coastal influence from Sydney Harbour, so temperatures can feel milder than the western suburbs.
What is driving Ultimo’s weather today?
Ultimo sits close to Darling Harbour and the Parramatta River, so sea breezes often cool the area in the afternoon. The bom ultimo observations from the nearest automatic weather station at Observatory Hill give the most reliable local reading. If the live forecast above shows a nor’easter, expect a fresher feel than the official temperature suggests.
How does Ultimo differ from wider Sydney weather?
Because Ultimo is built up and low-lying, it can be a few degrees warmer overnight than nearby coastal suburbs. However, it also catches the afternoon seabreeze earlier than Parramatta or Penrith. For the full sydney weather picture, check the Bureau’s Sydney metropolitan forecast, but for hour-by-hour changes use ultimo weather hourly data from the live feed above.
Where can I see the Ultimo weather radar?
The closest weather radar for ultimo weather radar is the Sydney (Terrey Hills) radar. It covers the city and inner suburbs well, though it can have beam blockage over tall buildings right above Ultimo.
Is Ultimo’s weather the same as the Sydney CBD?
Very similar. Ultimo is only 1–2 kilometres from the CBD. Both share the same sea-breeze patterns and temperature range. Use the CBD forecast from the ultimo weather bom page for the most accurate reading.
What time of day is Ultimo hottest?
Usually between 2pm and 4pm, before the seabreeze fully arrives from the east. Check ultimo weather hourly data on the live forecast above to see the exact temperature curve for today.
