Local Environmental Conditions
Water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen, within the neighborhood's edge. Woodland dominated by eucalypt and wattle, with wattle the more potent allergen of the two, not far from here. A park where mown turf grass and ornamental plane trees add to local grass and tree pollen, in the surrounding area.
Around Thornleigh Driving Range, river oak along the water gets the season underway before other species, reaching its high point sometime in late winter or early spring. 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 Thornleigh pollen forecast updated?

Does pollen in Thornleigh 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 Thornleigh 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 Thornleigh, 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. |
