After the worst grass pollen season on record the 1 in 3 people who suffer from hay fever or asthma in Canberra will be relieved to know that the grass pollen levels are at last beginning to subside.
The last 7 days has seen only LOW to MODERATE levels of grass pollen being recorded in our daily pollen counts, signalling a trend that should mark the end of grass pollen season for 2020.
Figure 1 shows the daily grass pollen counts for the months of September through to mid-December and confirms that we are seeing a gradual reduction in the daily grass pollen count. We haven’t experienced an EXTREME grass pollen day for over 2 weeks and the last HIGH grass day was recorded just over 1 week ago.
Grass pollen levels continue to be recorded at MODERATE to LOW levels, though we may expect this to continue to reduce through to the end of the month – which is a very good sign for the Christmas holiday celebrations.
