Victorians are being encouraged to prepare early for the health risks that can come with changing weather this spring and summer.

Victoria’s weather can be unpredictable, bringing different health risks across the season. Hot days and nights can increase the risk of heat-related illness.

High grass pollen levels can trigger hay fever and asthma symptoms. When combined with certain thunderstorms, they can also trigger thunderstorm asthma.

Rain followed by warm weather can also increase mosquito numbers and the risk of mosquito-borne diseases.

These conditions can develop quickly and sometimes occur at the same time.

Understanding the risks that may affect you, knowing where to find trusted information and making a plan early can help you respond when conditions change.

Victoria’s Chief Health Officer, Dr Caroline McElnay, said preparing before conditions change can help people protect themselves and those around them.

“Spring and summer are a great time to enjoy Victoria, but changing weather can also bring health risks,” Dr McElnay said.

“Knowing what is happening in your local area, or where you might be travelling across the state, and having a plan before you need it can make a real difference.”

Victorians can prepare by keeping up to date with local weather, warnings and health advice, understanding how seasonal conditions may affect them, and knowing what action they will take if conditions change.

“Whether it is extreme heat, thunderstorm asthma or mosquitoes, simple steps taken early can help keep you and your family safe,” Dr McElnay said.
