Autumn Weather Guide Australia
Complete guide to autumn weather in Australia (March, April, May).
Autumn in Australia Overview
Australian autumn (March to May) brings relief from summer heat with cooling temperatures and generally stable weather conditions. This is often considered the best time to visit many parts of Australia, with comfortable temperatures, reduced rainfall in the south, and the spectacular end of the wet season in the tropics. Autumn colours are visible in cooler regions, though less dramatic than in the Northern Hemisphere.
What to Expect in Autumn
Cooling temperatures across southern regions - pleasant 15-25°C days
End of cyclone and wet season in tropical north (usually by April)
Reduced bushfire risk as humidity increases
Vintage season in wine regions - harvest festivals throughout March-April
Spectacular autumn colours in the Blue Mountains, Adelaide Hills, and Victorian Highlands
Whale watching season begins as humpbacks migrate north along the east coast
Daylight hours decrease noticeably, especially in southern states
Sea temperatures remain warm through March, cooling by May
Common Autumn Weather Events
Late-Season Cyclones
Cyclone season officially ends in April, but late-season systems can occur. These can bring heavy rainfall to inland areas as they decay.
East Coast Lows
These intense low-pressure systems become more common from April, bringing heavy rain, strong winds, and dangerous coastal conditions.
First Frosts
Late autumn brings the first frosts to inland and elevated areas, signaling the approach of winter.
Fog
Morning fog becomes more common in valleys and coastal areas as temperature differentials increase between day and night.
Autumn Preparedness Tips
Transition Season Tips
- Layer clothing as temperatures can vary significantly throughout the day

- Update your flu vaccination before winter
Road Safety
- Be aware of fog on early morning drives
- Watch for wet leaves on roads which can be slippery
- Allow extra travel time as daylight hours reduce
- Check road conditions in alpine areas as snow season approaches
