Local Environmental Conditions
Gunnedah's Namoi Valley setting supports extensive cotton, wheat and other broadacre cropping on fertile black-soil plains, interspersed with the eucalypt woodland corridors famous for supporting one of Australia's densest koala populations. Wattle and native shrubs persist along waterways and travelling-stock reserves, while introduced pasture and crop species dominate cultivated land. This mix of woodland corridor and intensive cropping defines Gunnedah's broad seasonal pollen exposure.
Known as the koala capital of Australia, Gunnedah sits in the fertile Namoi Valley, where cropping dominates the landscape and shapes the local pollen calendar. Eucalypt and wattle pollen build from August, but cotton, wheat and other broadacre crops drive the heaviest pollen and dust loads from October through December. The valley setting can trap warm, still air, intensifying both pollen concentration and the risk of storm-triggered asthma when spring thunderstorms sweep through the Namoi.

How often is the Gunnedah pollen forecast updated?

Does pollen in Gunnedah 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 Gunnedah 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 Gunnedah, 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. |
