Know what to expect this summer

While many different climate drivers can influence Australia’s weather, it’s important to know what natural cycles and patterns increase the chance of above average temperatures.
Take, for example, El Niño and La Niña. These are complex weather patterns, or phases, that have the strongest influence on our country’s year-to-year climate variability. They form part of a naturally occurring climate cycle called El Niño-Southern Oscillation (or ENSO). This cycle occurs roughly every 1 to 8 years.
For us, El Niño typically leads to warmer, drier conditions over Eastern Australia, while La Niña usually leads to cooler conditions – with increased rainfall across much of the country.
As the Bureau of Meteorology recently declared, El Niño is now underway. Meaning we can expect a much drier summer across Australia. The last time we experienced a “strong” El Niño period was 2015-2016.
What El Niño means for us
While every El Niño is different, there are certain signs to take note of.
Below average rainfall increasing drought risk
Unusually high temperatures across Australia
Increased fire risk across Australia
Across Australia, we are likely to see above average temperatures and below average rainfall, which creates an increased risk for extreme heat and bushfires. For advice on how to protect your car and home this summer read here.
