Check the live forecast above before heading out, because Mittagong’s weather in the Southern Highlands can shift quickly with elevation and coastal influence.
What’s driving Mittagong’s weather today?
Mittagong sits about 600 metres above sea level on the Hume Highway, roughly halfway between Sydney and Canberra. That altitude means it’s often cooler than the coastal plains, with afternoon sea breezes arriving later than in Sydney. The live forecast above will tell you whether a trough or high-pressure system is dominating—look for cloud, wind shifts or a change in humidity to gauge how the afternoon will play out.
How accurate are the 7-day and 14-day outlooks?
Short-term forecasts for Mittagong are fairly reliable out to about three days, thanks to the Bureau’s high-resolution models. Beyond that, the 7-day and 14-day outlooks give a useful trend but can shift with synoptic patterns. For the most dependable plan, check the weather in mittagong 7 day forecast each morning and keep an eye on the mittagong weather radar for approaching showers or storms rolling in from the west.
What’s the weather in Mittagong tomorrow?
The live forecast above shows the official Bureau outlook for tomorrow. Generally, expect a morning minimum near 4-8°C, a maximum around 12-18°C depending on the season, and a chance of afternoon showers if a trough is passing.
Where can I see Mittagong weather radar?
The closest Bureau radar is at Sydney (Terrey Hills), which covers the broader region. For Mittagong-specific movement of rain or storms, check the mittagong weather radar composite on the BOM site or through WillyWeather, which blends radar with local topography.
Is there a 30-day outlook for Mittagong?
The Bureau of Meteorology publishes a monthly climate outlook, not a day-by-day 30-day forecast. For planning, look at the mittagong weather 30 days trend on the BOM’s climate page, but treat individual days beyond two weeks as a broad indicator only.
