Adelaide’s weather is classic Mediterranean – hot, dry summers and cool, wet winters. The live forecast above gives today’s conditions, which will align with the typical pattern for the season.
What drives Adelaide’s weather?
Adelaide sits on the Gulf St Vincent between the Mount Lofty Ranges and the coast, which shapes its local climate. In summer, high-pressure systems bring clear skies and heat, while winter sees cold fronts and rain from the Southern Ocean. The adelaide weather radar from the Bureau of Meteorology is the best tool to track approaching showers or storms. For a longer outlook, the adelaide weather 7 day forecast and adelaide weather 14 day predictions are updated daily.
How does the weather vary through the year?
January is typically the hottest month, with average maximums around 29–30°C, though heatwaves can push well above 40°C. Winter (June–August) is mild and rainy, with July the wettest month and average highs near 15°C. The adelaide weather yearly cycle is reliable, but El Niño and La Niña can shift rainfall and temperature patterns. For those planning short trips, the adelaide weather tomorrow forecast and adelaide weather 10 days outlook give practical guidance. Longer-range views like adelaide weather 21 day forecast are useful for rough planning but less precise.
Does Adelaide often get heatwaves?
Yes, several each summer. When a strong high-pressure system lingers over the Bight, hot northerly winds drive temperatures above 40°C for consecutive days. The severe weather warning page covers these events.
When is the wettest period?
June and July are the wettest months, with about 80 mm each. Rain comes from cold fronts and low-pressure systems moving from the west. The adelaide weather bom site provides hourly rainfall data.
How reliable is the 14-day forecast?
Generally moderate. Early days are quite accurate, but beyond 7–10 days the models have less skill for specific temperatures. For adelaide weather 7 day forecast the confidence is higher.
