Local Environmental Conditions
Here, close to home here, river oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia. Woodland dominated by eucalypt and wattle, with wattle the more potent allergen of the two, near this part of town. Mown grass and planted plane trees in a nearby park, adding to the seasonal pollen mix; this sits in the wider area.
River oak near the water opens the pollen calendar early, building through the depths of winter into September. Eucalypt and wattle in the woodland come next, as wattle bursts into flower, reaching maximum intensity across the August-September window. Grass pollen becomes the dominant allergen through spring, peaking in November, before continuing at a lower but still notable level through January and February.

How often is the Bonner pollen forecast updated?

Does pollen in Bonner 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 Bonner 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 Bonner, 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. |
