Authorities Warn South Western Sydney to Prepare for Dangerous Heatwave
25 Nov 2025
With conditions expected to reach record levels, officials are urging the community to take proactive steps to stay safe, especially vulnerable groups such as older adults, young children and people with chronic health issues.
Hydration Essential as Temperatures Rise
Staying hydrated remains one of the most effective protections against heat-related illness. Health experts recommend drinking two to three litres of water each day, even before feeling thirsty, while avoiding alcohol, caffeinated drinks and sugary beverages that can worsen dehydration. Families are encouraged to check on older relatives, neighbours and children to ensure they are drinking regularly.
Avoid Peak Heat and Keep Indoor Spaces Cool
To reduce the risk of heat stress, authorities advise limiting outdoor activities between 11 am and 5 pm. Residents without sufficient cooling at home can access public air-conditioned spaces such as libraries and shopping centres. Keeping blinds closed, wearing loose and light clothing, and using fans or air conditioning can help maintain a cooler indoor environment.
Extra Care for Vulnerable People and Animals
People who may struggle during heatwaves—including the elderly, those living alone or with disabilities—should be closely monitored. Pets also require added care, with constant access to fresh water and shade. Authorities stress that children and animals must never be left in parked vehicles, as temperatures inside can become life-threatening within minutes.
Recognising Heat-Related Illness
Authorities are urging the public to recognise the symptoms of heat-related conditions.
Heat exhaustion may present as:
-
nausea or vomiting
-
dizziness or fainting
-
headache
-
heavy sweating
-
weakness or muscle cramps
-
pale skin or irritability
If untreated, heat exhaustion can progress to heatstroke, a life-threatening emergency.
Signs of heatstroke include:
-
confusion or disorientation
-
slurred speech
-
seizures
-
rapid breathing
-
loss of consciousness
-
extremely high body temperature
-
hot, dry or profusely sweaty skin
Anyone showing signs of heatstroke requires immediate medical care.
Planning Ahead to Reduce Risks
Households are advised to prepare by ensuring cooling appliances work efficiently, planning for safe food and medication storage, and keeping emergency contacts handy. People with chronic conditions should consult their GP about managing their health during extreme heat. Identifying local heat-relief options, including shaded parks and air-conditioned community facilities, can help reduce risks.
Authorities say early preparation and community awareness are essential as South Western Sydney prepares for dangerous heat conditions in the weeks ahead.
