Maps are from the Bureau of Meteorology regional patterns of reduced rainfall and reduced root level soil moisture, particularly in the Canberra region during spring and early summer.

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.
