2019 pollen season update

Dec. 20, 2019

It's baking hot and only a few more sleeps left to Christmas. More importantly for us here at Melbourne Pollen we are at day 81 of the 2019 grass pollen season.

Day 81 because we count and forecast grass pollen daily from October 1 through to December 31, a total of 92 days.

Today's graph shows just what a season the 2019 grass pollen has been.

In our mid-season report we noted that the cumulative grass pollen count for 2019 was tracking above Melbourne's long-term average.

The cumulative grass pollen count is the daily sum of all the grass pollen caught in the trap since October 1.

Today's figure shows that the trend seen earlier has continued and the 2019 season - that's the green line - is still well above the long-term average, the dotted line.

2019 is still a long way short of being our worst season - that was 1993 - but it's been a much bigger season than we've had for a few years.

So, if you've noticed your hay fever's been bad this year, that could be the reason.

You can also see that Melbourne's grass pollen seasons start levelling off as we get towards the end of the year.

That's happening this year as well.

While the curve does flatten off, that doesn't mean we don't have any high or extreme grass pollen days, just a lot less of them.

In the past week we've had just one high day and only three so far for December.

In November there were 15 high or extreme grass pollen days. On average that's one every two days.

The good news is that today's forecasts for Melbourne has no high days for the next week.

Hopefully, that means we can stop worrying about the grass pollen season and start enjoying the Festive Season.
