Local Environmental Conditions
Stawell straddles the Wimmera's western grasslands and Grampians foothills, a former goldfields town where box-ironbark woodland remnants meet open grazing and cereal cropping country, with wattle a familiar sight along the old mining tracks each spring. As with much of temperate south-eastern Australia, grass pollen is the dominant late-spring concern locally, with an earlier and shorter wattle peak through August and September providing the season's first flush.
Stawell, on the edge of the Grampians ranges, sits in a transition zone between forested hills and open grazing plains. Tree pollen from eucalypts and wattle in the surrounding ranges builds from late winter, while grass pollen from pasture on the plains peaks October to November. The rain shadow cast by the Grampians keeps the district drier than Melbourne, generally producing a shorter, sharper grass pollen peak that tapers off as the district's typically dry summer conditions take hold from December.

How often is the Stawell pollen forecast updated?
The Stawell pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Stawell 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 Stawell 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 Stawell, 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. |
