Local Environmental Conditions
River oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia; this sits within easy reach. Nearby, a short distance from here, woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower. The general pattern described here holds fairly steady across nearby areas with similar land cover.
The bank's river oak kicks off the pollen season ahead of the rest, hitting its peak before most other trees flower, around July into September. As spring approaches, eucalypt and wattle in the nearby woodland become the dominant source, typically landing in August and September. As spring turns to summer, grass pollen rises toward its November high, before gradually tapering off through the peak of summer into February.

How often is the Cowan pollen forecast updated?

Does pollen in Cowan 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 Cowan 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 Cowan, 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. |
