What does the hourly forecast tell me?
The hourly breakdown gives you a practical view of how conditions shift through the day. You can see when the temperature peaks, when the seabreeze kicks in, and the timing of any showers. This is more useful than a single daily maximum, especially for planning outdoor work or a trip to the beach.
How reliable is the hourly data?
Short-term forecasts for the next 6 to 12 hours are generally reliable. Beyond that, confidence drops. The live forecast above uses the latest model runs from the Bureau of Meteorology. For a broader picture, pair it with the Australia weather hub or check the newcastle weather radar 512 km today to see approaching rain bands.
Where can I see the 7-day forecast for Newcastle?
The live forecast above shows today’s hourly data. For the full week, use the newcastle weather 7 day forecast on the Bureau of Meteorology site or check our Sydney Weather page for regional trends.
Is the hourly forecast updated in real time?
It updates every few hours as new model data becomes available. For the most current conditions, also look at the newcastle weather 14 day forecast for longer-range trends, and the live radar for immediate rain detection.
How do I read the wind direction in the hourly forecast?
Wind direction is given as the direction the wind comes from (e.g. a south-westerly blows from the south-west). Speed is in kilometres per hour. This helps you predict surf conditions and whether the afternoon seabreeze will cool things down.
