Thunderstorm asthma information in your language

Thunderstorm asthma can affect people with asthma or hay fever, particularly during Victoria's grass pollen season from October to December.

It occurs when high levels of grass pollen combine with specific thunderstorms, causing pollen grains to release tiny particles carried by wind gusts. These particles can be inhaled deeply into the lungs, quickly triggering asthma symptoms, even in those without a history of asthma. When many people experience symptoms simultaneously, it is called epidemic thunderstorm asthma.
