No grass pollen today

Sept. 4, 2013

What's in the air today?

There's a prediction doing the rounds, not one of ours, that today is a high/extreme pollen day in Melbourne. So we thought we'd have a look to see what's about at the moment.

We expected to see tree pollen and that's what we found. Europeans like elm and birch, some wattle (last Sunday was Wattle Day after all), pine and our old friend cypress. Plenty of it (counts in the hundreds) but that's not unusual for this time of year.

The Melbourne pollen calendar published by Ong et al (1995) also shows tree pollen counts in the hundreds for September.

Our forecasts are for grass pollen, Melbourne's major source of outdoor allergies, and there was no grass pollen on the slide so today is a low grass pollen day. We're not expecting to see much grass pollen until sometime in October but we'll keep a watch out for it. If you're sneezing today it may be because you have an allergy to tree pollen.
