While the Bureau of Meteorology hasn’t yet declared an El Niño in 2023, that’s not a reason to ignore the onset of the summer season and the anticipated perils created by dry conditions.
Australia’s weather is influenced by many different climate features, but El Niño and La Niña undoubtedly have the biggest influence. Both have global impacts on weather, bushfires, ecosystems and economies.
Reduced rainfall Warmer temperatures
Shift in temperature extremes Increased frost risk
Less tropical cyclones Later monsoon season
Increased fire danger (in southeast Australia) Decreased alpine snow depths
Increased rainfall
Cooler daytime temperatures (south of the tropics) Warmer overnight temperatures (in the north)
Shift in temperature extremes Decreased frost risk
More tropical cyclones Earlier monsoon season
According to the National Ocean Service, cycles of El Niño and La Niña typically last nine to 12 months but can sometimes last longer. The last La Niña for example, started in late 2020 and ran until mid-2022. They typically occur every two to seven years, but they’re unpredictable and don’t work to a set schedule! And El Niño generally occurs more frequently than La Niña.
El Niño sees rainfall move away from the western Pacific region. This means Australia’s rainfall is usually reduced during winter and spring, particularly across the eastern and northern parts of the continent.
Nine of the ten driest winter/spring periods on record for eastern Australia occurred during El Niño years*.
While no official El Niño has been declared, ongoing weather patterns in the region suggest it’s coming. Although a declaration would give emergency services more predictability about dry and hot conditions during the summer, long-range weather forecasts show the next three months are set to be hot and dry regardless. The National Council for Fire and Emergency Services (AFAC) has large parts of eastern and central Australia marked in red in its recent outlook.
It may seem surprising that after three years of heavy rain during La Niña, the risk of bushfire should be so high. However, the excessive rain has led to the rapid regrowth of vegetation and this increases the risk of fire, particularly in grassy areas.
It’s not only a current risk. The combination of decreased rainfall and increased maximum temperatures brought by an El Niño increases the frequency of high fire danger ratings and the risk of a significant fire danger season (particularly in southeast Australia) in the subsequent year too.
You might not be able to change the weather, but you can make sure people and properties are prepared with some simple steps.
Extreme heat or protracted periods of high temperatures are harmful to our health and to our pets and other animals. Look out for vulnerable residents and animals where possible.
Regular property inspections can help owners stay ahead of any issues and ensure they’re prepared for all weather conditions.
In the event of an emergency, like a bushfire, make sure everyone in your scheme knows what to do. Create a plan that includes everyone knowing where the nearest community evacuation area is, how emergency services will be contacted and include links for people to check the latest alerts, weather forecasts etc.
Now is a good time to check your level of insurance cover. Whether it’s strata insurance for the building or contents insurance for your personal belongings, make sure you have an adequate sum insured so you’re not left underinsured if an event occurs. Speak to BCB if you’re unsure.
We all have a role to play in helping protect the communities we represent. As a broker, our role is to help prepare for insured events and reduce the likelihood of a claim, as well as help you navigate through the claims process if you are impacted.
