Heatwave Safety

Published on Wednesday, 7 January 2026 at 2:17:50 PM

Heatwaves are periods of unusually hot weather that can last for several days and have serious impacts on health, particularly in regional and remote communities. Extreme heat places extra stress on the body and can affect anyone, not just those who work outdoors. Being prepared and knowing how to protect yourself and others can reduce the risk of heat-related illness.

What Is a Heatwave?

A heatwave occurs when temperatures are much hotter than usual for several days in a row. High overnight temperatures can make heatwaves especially dangerous, as the body does not get a chance to recover. Heatwaves can lead to dehydration, heat exhaustion and heatstroke, which can be life-threatening if not treated early.

Who Is Most at Risk?

Some people are more vulnerable during extreme heat, including:

  • Older adults

  • Babies and young children

  • People with chronic medical conditions

  • Pregnant women

  • People taking certain medications

  • Those who live alone or have limited access to cooling

  • Outdoor workers and people exercising in the heat

How to Stay Safe During a Heatwave

Keep Cool

  • Stay indoors during the hottest part of the day

  • Close curtains and blinds to block out heat

  • Use fans or air-conditioning if available

  • Spend time in air-conditioned buildings such as shopping centres or community facilities

  • Take cool showers or baths to lower body temperature

Stay Hydrated

  • Drink water regularly, even if you do not feel thirsty

  • Keep a water bottle with you

  • Avoid alcohol, sugary drinks and caffeine as they can increase dehydration

  • Eat light meals and avoid heavy or hot foods

Reduce Physical Activity

  • Plan outdoor activities for early morning or late evening

  • Avoid strenuous exercise during peak heat

  • Take frequent breaks if you must be outdoors

  • Wear light, loose-fitting clothing made from breathable fabrics

  • Use sunscreen, a hat and sunglasses when outside

Look Out for Others

Heatwaves can affect people differently, so it is important to check in on others. Regularly contact:

  • Elderly neighbours

  • Family members and friends

  • People with disabilities or health conditions

  • Parents of young children

Never leave children or pets in cars, even for a short time, as temperatures can rise dangerously fast.

Know the Warning Signs

Seek medical help immediately if someone shows signs of heat-related illness, including:

  • Dizziness or confusion

  • Headache

  • Nausea or vomiting

  • Muscle cramps

  • Hot, flushed or dry skin

  • Fainting or collapse

Be Prepared

  • Monitor weather forecasts and heatwave warnings via Emergency WA and The Bureau of Meteorology

  • Have a plan for staying cool at home

  • Make sure fans and air-conditioners are working

  • Stock up on water

  • Know where to go if your home becomes too hot

Extreme heat can be dangerous, but with preparation and simple actions, the risks can be reduced. Staying informed, looking after yourself, and checking on others helps keep the whole community safe during heatwaves.
