Did you know heatwaves in Australia are becoming longer, hotter and more frequent?
Australia’s climate is changing and heatwaves are one of the clearest signs.
Research shows that heatwaves across Australia have increased in frequency, duration and intensity since the 1970s, with trends accelerating in recent decades.
Australia has already warmed by around 1.5°C since 1910, contributing to more extreme heat events nationwide.
Studies also show that climate change is making extreme heat events more likely and more severe, with some recent heatwaves estimated to be up to five times more likely due to rising global temperatures.
And it’s not just about hotter days —
heatwaves are now lasting longer, exposing people to prolonged periods of heat stress.
This shift means heat is no longer a seasonal issue — it’s an ongoing risk across workplaces, sports and everyday life.
Understanding the risk is the first step.
Managing heat exposure is the next.
Stay prepared for changing conditions.
