Heat Health

This summer is predicted to be warmer and drier summer that usual, it means we will see above – above average daytime temperatures and a number of hot nights. When this occurs we can see heatwave conditions which have significant implications on health, essential services and infrastructure that supports our everyday living.

By being prepared and aware of heatwave conditions you can protect yourself, your family and neighbours from the potential deadly effects of heatwaves.

Extreme heat or heatwave is a period of unusually and uncomfortable hot weather that could negatively affect human health. Extreme heat can also affect community infrastructure such as power supply and other services. Extreme heat can affect everyone, however some people are more vulnerable such as the elderly, young and those already ill.

A system has been developed by the Victorian Health and Human Services (the department) to notify organisations, groups and individuals when extreme heat or heatwaves are likely to negatively affect human health.

Through monitoring the Bureau of Meteorology’s 7-day forecast maximum and minimum temperature. When the heat health temperature threshold is reached for a specific weather forecast district, a heat health alert is issued.

The heat health threshold is worked out by adding the maximum daytime temperature and minimum night time temperature and then dividing it by two. For example Daytime maximum of 39⁰C and a minimum night time temperature of 21⁰C, 39 + 21 = 60 /2 = 30⁰C

In the South West weather forecast district, a heat health temperature threshold of 30⁰C. When this threshold is reached a public alert will be issued.

During extreme heat it is easy to become dehydrated or for your body to overheat. If this happens, you may develop heat cramps, heat exhaustion or even heatstroke. Extreme heat can also make existing medical conditions worst.

With some forward planning and smart thinking you can help ensure you, your family and pets cope with and remain healthy during the heat.

The young, elderly and those with medical conditions can be at higher risk to heat related illnesses, as well as those who are isolated and living alone. It’s important that we check on these members of the community to ensure that they are ok during extreme heat and heatwaves.
