Local Environmental Conditions
Here, just around the area, the riverbank shelters river oak, whose pollen spreads readily on the wind from spring onward. Here, within the neighborhood, a mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia. A park where mown turf grass and ornamental plane trees add to local grass and tree pollen, within easy reach.
The waterside river oak is consistently first to release pollen each year, getting an early start, typically cresting between July and August. Once river oak fades, eucalypt and wattle in the woods carry the season forward, reaching its high point through August and into October. Grass pollen builds through spring and peaks in November, before pollen counts gradually decline through January and February.

Does pollen in Hunters Hill 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 Hunters Hill 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 Hunters Hill, 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. |
