Local Environmental Conditions
Nearby, in the surrounding area, water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen. Nearby, within the local area, tree cover made up mostly of eucalypt and wattle, wattle in particular a well-known seasonal trigger. The broader area tends to mirror this pattern, with only minor local variation.
Water-edge river oak is usually the first allergenic tree active here, 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, reaching its high point through August and into October. Grass pollen counts rise through spring, reaching their peak around November, before pollen counts gradually decline through January and February.

Does pollen in Big 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 Big 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 Big 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. |
