Heatwave hazard

Heatwave hazard in the Cessnock LGA

Heatwaves are becoming more frequent, lasting longer, and increasing in intensity – and they pose serious health risks to our community. Extreme heat causes more illness and death in Australia than any other natural hazard, making it vital that we all understand how to stay safe during hot weather.


What is a heatwave?

A heatwave is an extended period of unusually high temperatures. In Cessnock, heatwaves often occur in summer and early autumn, but can happen at any time of year. The effects can be especially dangerous when high temperatures persist for several days and nights without relief.


Who is most at risk?

While everyone can be affected by extreme heat, certain groups are more vulnerable, including:

  • Older adults, especially those with chronic health conditions
  • Pregnant women, who may be more sensitive to heat stress
  • Infants and young children, who can overheat quickly
  • People with existing health conditions, such as heart disease, high blood pressure, kidney disease, or gastroenteritis
  • People taking certain medications that affect how the body regulates temperature
  • Outdoor workers, such as labourers, gardeners, and emergency responders
  • People who live alone or are socially isolated, and may not have support nearby

How to prepare for and manage a heatwave

Simple actions can help you stay safe during periods of extreme heat:

  • Access advice from NSW Health
  • Keep an eye on the weather forecast and prepare in advance for hot days
  • Use the HeatWatch web app to monitor conditions in your local area
  • Wear loose-fitting, light-coloured clothing
  • Avoid direct sun exposure, especially during the hottest part of the day (usually mid-afternoon)
  • Stay indoors where possible - ideally in a cool or air-conditioned space like our Libraries, Aquatic Centres, and Shopping Centres
  • Keep your home cool by closing curtains, doors, and windows early in the day
  • Use fans or air conditioning if available
  • Stay hydrated by drinking plenty of water - avoid tea, coffee, and sugary or alcoholic drinks
  • Take a full water bottle with you when going outdoors
  • Look out for others - check in with elderly neighbours, family members, and friends who may need assistance
  • Follow your doctor’s advice if you have a chronic health condition

Heat-related illness - know the signs

Watch for symptoms of heat exhaustion or heatstroke, such as:

  • Dizziness or fainting
  • Headaches
  • Rapid heartbeat
  • Nausea or vomiting
  • Confusion or disorientation

If someone shows these signs, move them to a cool place, give them water if they are conscious, and seek medical help immediately.


In an Emergency

If someone is seriously unwell or showing signs of heatstroke, call Triple Zero (000) immediately.
