Local Environmental Conditions
Located not far from here, this area has the riverbank shelters river oak, whose pollen spreads readily on the wind from spring onward. Here, just around the area, a stand of eucalypt with wattle through the understorey, wattle ranked among the region's sharpest allergens. Small shifts in elevation or soil type can move these figures a little either way.
River oak by the water is typically first out of the gate, usually the first pollen source active, peaking sometime in July or August. The nearby eucalypt and wattle stands take the lead as winter turns to spring, typically landing in August and September. Spring brings rising grass pollen that crests in November, and remaining a significant allergen right through summer until it eases in February.

Does pollen in Macarthur 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 Macarthur 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 Macarthur, 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. |
