Local Environmental Conditions
Nearby, just outside the immediate area, the nearest creek or river hosts river oak, among the most allergenic wind-pollinated trees found on watercourses. This area, close by, has a canopy of eucalypt threaded with wattle, wattle chief among them for allergenic potency here. Nearby weather stations report comparable trends across the broader stretch of the region.
Around Potters Gorge, eucalypt and wattle in the woods pick up where river oak leaves off, usually peaking from August into October. Along the waterway, river oak releases pollen first, starting well before the main spring rush, topping out around September. By late spring, grass pollen is climbing steadily toward a November high point, before gradually tapering off through the peak of summer into February.

Does pollen in Worsley 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 Worsley 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 Worsley, 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. |
