Local Environmental Conditions
A waterway lined with river oak, a wind-pollinated species and one of the more potent allergen sources along Australian creeks and rivers; this sits within easy reach. Woodland dominated by eucalypt and wattle, with wattle the more potent allergen of the two; this sits not far from here. Local microclimate and soil conditions can push these figures slightly higher or lower.
Along the waterway, river oak releases pollen first, peaking in mid-winter through September. The nearby eucalypt and wattle stands take the lead as winter turns to spring, usually hitting its highest point sometime between mid-August and mid-September. Grass pollen takes over next, building to a peak around November, before continuing at a lower but still notable level through January and February.

How often is the Cadia pollen forecast updated?

Does pollen in Cadia 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 Cadia 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 Cadia, 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. |
