Australia Faces Extreme Weather Rollercoaster
19 Sep
Summary
- South-east Australia braces for warmest September day in years.
- Temperatures set to swing dramatically between heat and cold.
- Strong El Niño developing, increasing fire and heatwave risks.
Residents in south-eastern Australia are set to experience unusually warm weather, with September temperatures predicted to be 6C to 12C above average over the upcoming weekend. Coastal areas may reach the high 20s Celsius, while inland locations could see temperatures in the low to mid 30s. This phenomenon is driven by weather systems in Western Australia and the Tasman Sea.
Meteorologists describe this fluctuation as a 'spring rollercoaster.' For example, Hobart is forecast to reach 27C on Sunday before dropping to a much cooler 14C on Monday. These swings are attributed to fast-moving weather systems bringing hot, northerly winds followed by cooler southerly air.
The Bureau of Meteorology's spring outlook indicates warm and dry conditions, largely influenced by a strong El Niño expected to peak later in spring or summer. This El Niño increases the likelihood of warmer, drier weather, higher fire danger, and heatwaves, particularly in regions like Queensland and New South Wales.
