Local Environmental Conditions
This area, just outside the immediate area, has river oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia. Nearby, in the surrounding area, woodland dominated by eucalypt and wattle, with wattle the more potent allergen of the two. Nearby, close by, a green space of mown lawn and planted plane trees, both feeding into local pollen counts.
The water-adjacent river oak is an early riser, reaching its high point sometime in late winter or early spring. Further into late winter, the area's eucalypt and wattle stands drive the pollen count, reaching maximum intensity across the August-September window. Through spring, grass pollen climbs steadily toward its November peak, before continuing at a lower but still notable level through January and February.

How often is the Greendale pollen forecast updated?

Does pollen in Greendale 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 Greendale 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 Greendale, 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. |
