Victorians brace for a tough grass pollen season

VICTORIANS are being urged to prepare for a challenging grass pollen season, with forecasts suggesting that 2024 may bring high pollen levels similar to last year, increasing risks for people with hay fever and asthma.

AirHealth, which operates the Melbourne Pollen monitoring program in collaboration with the University of Melbourne, predicts that while a dry winter might delay the season’s start, the arrival of spring rainfall could trigger a rapid increase in pollen levels.

Grass pollen, a significant trigger for asthma and hay fever, poses particular risks when combined with weather events like thunderstorms, potentially leading to incidents of thunderstorm asthma.

AirHealth chief operating and scientific officer Dr Edwin Lampugnani said environmental factors were key in determining the severity of the season, with current predictions pointing to another difficult year for allergy sufferers.

“At this stage, we are expecting a bigger than average grass pollen season, similar to last year.

“Forecasted rainfall could lead to increased grass growth and higher pollen levels later in the season. Our team is closely monitoring these conditions to ensure we provide the most up-to-date information to the public.”

The Melbourne Pollen App, developed to help residents track pollen levels, will again play a crucial role in helping those affected manage their exposure throughout the season.

Professor Bruce Thompson, head of health sciences at the University of Melbourne, said fluctuations in pollen levels impact people with respiratory conditions like asthma.

“With potential late-season rains, we could see more frequent and severe asthma episodes.

“It’s crucial for people with asthma to be prepared and have their medication plans in place to avoid potentially serious health events.”

He also noted that those who experience hay fever, even if they haven’t had asthma in the past, should be particularly cautious as high pollen levels can sometimes trigger asthma symptoms.

Last year, Melbourne experienced 30 high or extreme pollen days, and experts warn that this year may bring similar conditions if the predicted spring rainfall occurs.

Those with asthma or hay fever are advised to stay informed and ensure their treatment plans are up to date as the pollen season intensifies.
