WARNING: There is a thunderstorm asthma alert for central and southwest areas of Victoria for Friday 23 October 2026. Forecast thunderstorm weather is expected to increase the risk of thunderstorm asthma.  The risk to asthma sufferers is forecast to be MODERATE in central and southwest regions of Victoria.

Grass pollen season can lead to increased asthma and hay fever cases, including the potential for thunderstorm asthma. This phenomenon occurs when high pollen levels and specific thunderstorms trigger asthma symptoms in many people. Pollen particles released before a storm can be inhaled deep into the lungs, causing breathing difficulties. It’s vital for those with asthma or hay fever to be aware and take precautions during this season.

Here are some things you can do to prepare for pollen season:

  • If you’ve ever had asthma – talk to your doctor about what you can do to help protect yourself from the risk of thunderstorm asthma this pollen season. Remember taking an asthma preventer properly and regularly is key to preventing asthma, including thunderstorm asthma.
  • If you have hay fever – see your pharmacist or doctor for a hay fever treatment plan and check if you should have an asthma reliever puffer – which is available from a pharmacy without a prescription.
  • If you have hay fever, and especially if you experience wheezing and coughing with your hay fever, it is important to make sure you don’t also have asthma. Speak to your doctor today about whether or not you might have asthma.
  • It’s important for everyone in the community to know the four steps of asthma first aid so they know what to do if they or someone is having an asthma attack.
  • And finally, where possible, avoid being outside during thunderstorms from October through December – especially in the wind gusts that come before the storm. Go inside and close your doors and windows. If you have your air conditioning on, turn it to recirculate.
