Southeastern Australia will experience a large temperature contrast on Monday, with snow falling in Tasmania while parts of New South Wales reach 35°C amid Extreme fire danger. A cold front crossing southeastern Australia on Monday will cause cold southwesterly winds originating from the Southern Ocean to clash with much warmer air over the Australian continent. This weather pattern is typical in spring and often causes a stark contrast of summer-like heat and wintery cold weather.

A wave of summery heat moving across southeastern Australia brought a very warm Saturday, with another hot day on Sunday for Australia’s southeastern capitals. Adelaide and Melbourne record hottest day of spring on Saturday The burst of summer sweeping across southeastern Australia brought the warmest day of spring to both Adelaide and Melbourne yesterday. Adelaide reached a maximum of 26.5°C on Saturday, making it the hottest day since last autumn.

A Brief Burst of Summer Sweeps Across the Southeast Summer is making an early appearance across parts of South Australia, New South Wales and Victoria this Sunday, with temperatures set to soar into the mid-30s. September has already been unusually warm across Australia's southern states, with the persistent warmth contributing to an early end to the ski season at all resorts apart from Perisher Valley. Now, another burst of heat is on the way.

Australia is about to pass an annual daylight milestone, with days set to become longer than nights across the country as the spring equinox approaches. What is the equinox? Earth’s orientation relative to the Sun changes throughout the year because Earth has an axial tilt of about 23.4 degrees relative to its orbital plane around the Sun.

Perisher in New South Wales is the last Australian ski resort with a few ski lifts still operating, and it has announced plans to try to stay open until next Friday, September 25, despite a record low snow depth for mid-September at nearby Spencers Creek. This will be good news for Queensland travellers who are venturing south for the first week of the Queensland school holidays – with Queensland public schools breaking up this Friday afternoon.

A spring chill is gripping southeastern Australia this week, with temperatures dropping below zero degrees in five states and territories on Thursday morning. A cold and dry air mass combined with relatively light winds and clear skies over southeastern Australia on Wednesday night. This combination allowed for efficient radiative cooling near the surface, which caused temperatures to plummet.

Maximum wave heights nearing six metres were recorded near Sydney on Wednesday morning as cold and blustery southerly winds caused a sharp temperature drop along Australia’s east coast. The satellite images below show a large field of speckled cloud spreading over the Tasman Sea on Wednesday morning. This cloud pattern is a typical feature in the cooler months of the year and occurs when cold Southern Ocean air moves over comparatively warmer waters in the mid-latitudes.

Temperatures are dropping rapidly as a cold front surges across southeastern Australia, with the coldest air enveloping Tasmania and leaving our southernmost state with a heavy coating of snow to low levels this Tuesday.

A brief return to chilly weather is on its way to southeastern Australia, with Tasmania and parts of the mainland in line for a wild, windy, very wintry Tuesday. We wrote last week about the spring temperature "see-saw", and the temperature contrasts will be stark in the first few days of this week across Australia's most populated corner. Melbourne's maximum will drop from around 19°C this Monday to around 14°C on Tuesday and just 13°C on Wednesday. The average September maximum is 17.3°C.
