Is your asthma made worse by allergens in the air?

Our local AusPollen Apps provide daily levels of pollen in the air.

To help us evaluate the usefulness of our Apps and how we can improve this service, we invite you to complete a short questionnaire before and after the pollen season.

This research will help us site future pollen count stations and determine whether there are local triggers that make hay fever and asthma worse.

Best regards,

The AusPollen team.


Statewide look at Victoria's grass pollen season


Victoria_cumulative_2018.png

My last post discussed how Melbourne’s grass pollen season was progressing.

This week I’ll cast an eye over all eight Victorian pollen monitoring sites and take a quick look at the season elsewhere in the state.

One way to measure the season's progress is to plot the cumulative grass pollen count at each site since October 1.

Today's very busy figure shows that plot, along with a map to help orient you to the locations of our sites.

The dashed red line shows the long-term average for Melbourne, with each solid line showing the cumulative grass pollen level at one of the Victorian sites.

A mixed picture emerges of the 2018 grass pollen season.

The brown line shows Melbourne itself. The cumulative count continues to be below average and seems to have flattened. That's what we’d expect for a milder grass pollen season.

That impression is borne out by the orange line of Burwood. It’s been an even milder season there and the total grass pollen count is only 60% of that at Melbourne.

Burwood's count is lower presumably because it’s just that little bit further for the grass pollen to travel from the pastures and grazing land west and north of the city.

Contrast Melbourne’s mild season with the grey line of Churchill. Churchill leads the state in terms of total grand grass pollen and the line is still climbing.

I guess they’ll be sneezing in the Latrobe Valley for a while yet.

Much like Churchill, cumulative grass counts in Dookie (light blue), Creswick (gold) and Hamilton (green) are all on the way up and show now sign of flattening.

Dookie has been the worst place for high and extreme grass pollen, days when the average grass pollen concentration was 50 grains or more per cubic metre of air (a high day) or 100 grains or more (an extreme day).

Dookie has had 17 of these days so far this season, one more than Churchill and Creswick.

We’ll continue our counting at all eight sites through to the end of the year and provide you with daily forecasts and updates.
