Local Environmental Conditions
River oak lines the bank, contributing some of the season's more persistent wind-borne pollen, in the wider area. Tree cover made up mostly of eucalypt and wattle, wattle in particular a well-known seasonal trigger, not far from here. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
River oak by the water is typically first out of the gate, usually peaking sometime between July and September. The area's eucalypt and wattle trees pollinate through late winter and early spring, climbing steadily through late winter to a peak in August or September. As spring turns to summer, grass pollen rises toward its November high, then holding at a high level well into January before easing off.

Does pollen in Bournda 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 Bournda 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 Bournda, 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. |
