Lots of charcoal particles observed in our daily pollen count slides from 8th January. These particles are likely derived from the northward spread of smoke (visible over the ACT) from the extensive bushfires in Victoria. For advice see lnkd.in/gSgTTHxY from ACT Health

The Canberra grass pollen daily count for 2025 started with a bang and ended with a whimper. - strong grass pollen season began in late September - by mid November the daily counts began to plateaus to reach below average levels by end of December. - only 3 EXTREME grass pollen days were recorded.
The figure depicts the cumulative pollen count curve from October to December 2025 and compares it to all other years with data. The 2025 October to early November counts tracked those from previous above average years (2020-2023). However, by mid November the daily counts began to stabilise to moderate-low levels and the cumulative curve plateaus to eventually reach below average levels by the end of December.

An inset histogram graph depicts the proportion of recorded grass pollen levels (LOW, MODERATE, HIGH, EXTREME) for 2025 compared to El Niño and La Niña years showing that 2025 lies between the proportions that characterise El Niño years vs. La Niña years.

It seems a little early to start talking about the pollen-hay fever season in Canberra, but over the weekend we saw the first hint of elevated pollen levels in Cupressaceae pollen (Cypress pine family) - 14 grains/m3 - still LOW, but hinting at the beginnings of elevated levels to come.

Canberra is going through a severe dry spell with rainfall levels well below average for the period from August to October (according to www.longpaddock.qld.gov.au). This has led to drying off of grasslands and a reduction in pollen production during the peak period of the grass pollen seasoon.
