Local Environmental Conditions
The nearest stream or river hosts wattle and casuarina, two of the most allergenic early-season trees, in the wider area. Nearby, within easy reach, a stand of plane tree and eucalypt, the latter ranked among the region's most potent tree allergens. This area, close to this spot, has grass and ornamental trees within the park boundary contribute modestly to grass and plantain and weed levels.
In O'Connor, temperatures climbing to 9.9°C by September likely mark the start of the main pollen release, with humidity around 69% helping keep counts airborne. Warmer conditions by December (17.9°C, 64% humidity) sustain grass pollen through the season, before rainfall of 104mm in March and cooling toward 5.6°C in June bring the season to a close.

How often is the Canberra pollen forecast updated?
The Canberra pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Canberra come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Canberra based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Canberra, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
