Spring temperature see-saw in southeastern Australia

Temperatures will bounce around in southeastern Australia this week as contrasting air masses battle it out in a seasonal tug-of-war.

Early spring is typically a time for variable temperatures in southern parts of Australia as hot continental air masses interact with much colder pools of air moving up from the south.

This temperature see-saw is even more noticeable than usual this year due to an abnormally hot air mass that built up over the Australian continent in the final weeks of winter.

Sydney is one place that will see large temperature variations this week, with a brief period cool weather today following a bout of record-challenging warmth late last week.

The city experienced one of its warmest winter days on record when the temperature reached 30.3°C on Friday last week. This was followed by maximums of 27.4°C on Sunday and 25.4°C on Monday, which were around 5 to 7°C warmer than average for the opening days of spring.

Looking ahead, maximum temperatures are forecast to bounce up and down in Sydney during the rest of this week:

  • 19°C on Tuesday
  • 22°C on Wednesday
  • 29°C on Thursday
  • 29°C on Friday
  • 25°C on Saturday
  • 23°C on Sunday

Melbourne’s week is looking similarly variable and equally difficult to plan what clothes to wear from day-to-day:

  • 17°C on Tuesday
  • 21°C on Wednesday
  • 23°C on Thursday
  • 26°C on Friday
  • 18°C on Saturday
  • 19°C on Sunday

Adelaide won’t escape the turbulent temperatures this week either:

  • 20°C on Tuesday
  • 26°C on Wednesday
  • 27°C on Thursday
  • 22°C on Friday
  • 18°C on Saturday
  • 17°C on Sunday

Hobart’s temperature range will also be noticeable with a mix of warm and cool days ahead:

  • 15°C on Tuesday
  • 20°C on Wednesday
  • 21°C on Thursday
  • 19°C on Friday
  • 15°C on Saturday
  • 16°C on Sunday

The contrasting air masses that produce large temperature fluctuations in southern Australia at this time of year can also produce blustery winds and outbreaks of rain and storms. Be sure to keep an eye out for a burst of wet, stormy and windy weather in southern and southeastern Australia later this week.
