Local Environmental Conditions
River oak crowds the water's edge here, a well-known contributor to local casuarina pollen counts, just outside the immediate area. Nearby, not far from here, a mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia. Parkland with regularly mown grass and planted plane trees, both sources of seasonal pollen, close to this spot.
Water-edge river oak is usually the first allergenic tree active here, arriving ahead of the rest of the season, cresting around mid-winter. Eucalypt and wattle in the nearby woodland follow through late winter and early spring, building to its sharpest point across August and September. Grass pollen builds through spring and peaks in November, and remaining a significant allergen right through summer until it eases in February.

Does pollen in Harris Park 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 Harris Park 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 Harris Park, 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. |
