Local Environmental Conditions
This area, near this part of town, has river oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall. Local microclimate and soil conditions can push these figures slightly higher or lower.
Water-edge river oak is usually the first allergenic tree active here, peaking in mid-winter through September. Grass pollen becomes the dominant allergen through spring, peaking in November, then persisting at a reduced but still meaningful level into the new year. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

Does pollen in Hamelin Pool 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 Hamelin Pool 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 Hamelin Pool, 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. |
