Local Environmental Conditions
A stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months; this sits close to this spot. Nearby, within easy reach, eucalypt and wattle growing together, with wattle's fine pollen especially potent during its short flowering window. The broader area tends to mirror this pattern, with only minor local variation.
Around Boarding House Campsite, along the waterway, river oak releases pollen first, reaching its high point sometime in late winter or early spring. Eucalypt and wattle nearby take over the pollen calendar through late winter, reaching maximum intensity across the August-September window. As spring turns to summer, grass pollen rises toward its November high, before gradually tapering off through the peak of summer into February.

How often is the Glenoran pollen forecast updated?

Does pollen in Glenoran 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 Glenoran 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 Glenoran, 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. |
