As well as pollen grains this Christmas image features the festive fungal spores of Lophiostoma and Alternaria
In my last post I compared Bambi and Godzilla, with Bambi being Melbourne's grass pollen season and Godzilla being Canberra's season. Well, the Canberra season marches on. Perhaps not the most frightening season they've ever seen but, propelled on by some recent good rainfall, certainly well on track for an above average year.
Meanwhile, here in Melbourne we're getting pretty used to our mild summer weather and a well-entrenched Bambi pollen season. Today's graph shows its looking remarkably like '08, our mildest pollen season yet. That's all courtesy of a dry spring with around half the average rainfall.
But even Bambi is a wild animal capable of leaving a mark. That means we've had a few bad days for hay fever. So far this season there have been 3 high grass pollen days, which are days when the grass pollen count is over 50 grains per cubic metre of air. But on average we can expect 12 high days a season and 9 extreme days as well (days when the grass pollen count is an eyewatering 100 grains or more). I can't see any of those in prospect this year and in all likelihood we may well have seen the last of Bambi's wild side as well.
Read Craig Butt's story on our first high pollen day in The Age.
The other day our Canberra colleagues blogged about how this season is trending towards record levels of grass pollen - they are warning of a potential Godzilla-like hay fever season in the nation's capital! Today's graph shows you how Melbourne season is doing in comparison.
The graph shows the cumulative total of grass pollen grains for the season. That is, each daily count is added to the sum of all the previous daily counts from October 1 – that’s the red line in today’s graph. Compare that line to the blue line (our average grass season) and the two dashed lines, our worst season (1993) and our mildest season (2008).
A little early to tell yet but on the face of it 2015 is shaping up more Bambi than Godzilla.
We'll check in on progress again in a couple of weeks.
Meanwhile, here's some great advice on how to manage your hay fever.
