Local Environmental Conditions
The riverbank shelters wattle and casuarina, two trees whose pollen travels readily on the breeze; this sits in the surrounding area. Woodland dominated by plane tree and eucalypt, with eucalypt a leading regional tree-pollen allergen; this sits just outside the immediate area. Ground-level conditions like local landscaping can nudge these figures slightly either way.
In Upper Sturt, temperatures climbing to 13.1°C by September likely mark the start of the main pollen release, with humidity around 70% helping keep counts airborne.

Does pollen in Adelaide Hills Council come from nearby or far away?

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 Adelaide Hills Council 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 Adelaide Hills Council, 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. |
