But a very strong El Niño—a natural weather phenomenon that drives variations in temperature and winds across the Pacific—could make this summer a sweltering one.
This raises the question: Are we ready for extreme heat? Our new research examined how Australia's Greater Sydney region is preparing for surging temperatures and more frequent heat waves. In particular, Western Sydney is known for its stifling temperatures, at times being the hottest place on the planet.
We found this citywide approach involves much more than simply telling people what to do when temperatures soar. Many Australians know how to cope with hot weather. We drink plenty of water, close blinds and curtains, stay indoors when the sun is at its strongest and regularly check on family, friends and neighbors.
However, not everyone can act on it. For some people, staying cool is much easier said than done. Not everyone can afford to keep the air conditioner running.
Not everyone has a well-insulated home, particularly those living in older homes. Not everyone is well connected to their neighbors and wider community. Our latest research took a closer look at how one city is preparing for extreme heat.
The Greater Sydney Heat Taskforce, established in 2023 and led by the Western Sydney Regional Organisation of Councils and Resilient Sydney, aims to help nearly 5.6 million Sydneysiders cope with rising temperatures. This task force brought together 373 representatives from more than 40 organizations across government, health, emergency services and other sectors. Over an 18-month period, these representatives developed the Greater Sydney Heat Smart City Plan.
