Check the live forecast above for your immediate conditions, then use a weather chart to see the bigger picture. A synoptic chart shows pressure systems, fronts and wind patterns across Australia, helping you understand what drives the weather for the next 7 to 10 days.
What does a weather chart actually show?
A weather chart, or synoptic chart, is a snapshot of atmospheric pressure at sea level. Lines called isobars connect points of equal pressure. Closely spaced isobars mean strong winds; wide spacing means lighter winds. High-pressure systems (H) bring clear skies, while low-pressure systems (L) often bring rain and cloud. Cold fronts appear as lines with triangles, and warm fronts as lines with semicircles. For a practical look at your region, check the weather chart Sydney or weather chart Melbourne pages for local detail.
How do I read a 7 day synoptic chart for Australia?
Start with the broad pattern. A weather chart Australia will show a series of highs and lows moving east. Look for a trough—an elongated low-pressure area—which often triggers showers. The severe weather warning page will alert you if a system is dangerous. For planning, a 10 day synoptic chart Australia gives you a reliable outlook, though confidence drops after day 7. If you need a weather chart tomorrow, compare the current chart with the forecast for the next 24 hours to see how fronts shift.
Where can I find a weather chart for my state?
For a weather chart NSW, check the Bureau of Meteorology’s regional analysis. For weather chart QLD, look at the same source but zoom into the Queensland region. Both are updated every six hours.
What is the difference between a 7 day and 10 day synoptic chart?
A 7 day synoptic chart is more reliable for day-to-day planning. A 10 day synoptic chart Australia shows the likely broad pattern but has lower accuracy for exact timing of fronts or rain bands.
How often are weather charts updated?
The Bureau of Meteorology issues a new synoptic chart every six hours (at 00:00, 06:00, 12:00 and 18:00 UTC). Forecast charts for the coming days are updated at least twice daily.
