Local Environmental Conditions
Located not far from here, this area has river oak crowds the water's edge here, a well-known contributor to local casuarina pollen counts. Woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower; this sits within the local area. This area, in the vicinity, has a park where mown turf grass and ornamental plane trees add to local grass and tree pollen.
Along the waterway, river oak releases pollen first, usually peaking sometime between July and September. As spring approaches, eucalypt and wattle in the nearby woodland become the dominant source, cresting around August and September in the year's sharpest tree-pollen spike. As spring turns to summer, grass pollen rises toward its November high, holding through the summer months before tapering off by late February.

How often is the Glenrowan pollen forecast updated?

Does pollen in Glenrowan 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 Glenrowan 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 Glenrowan, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
