Local Environmental Conditions
This site in Mount Stirling is surrounded mainly by farmland, with some open grassland. A nearby park adds mown lawns and planted trees to the local pollen mix. Grasses are a major source, with pigweed adding to the weed pollen load. Pasture and uncultivated field edges in the farmland provide room for grasses and weeds.
Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. The season closes with pigweed from early summer into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. Within each of these periods, warm, dry and windy days push levels higher, while rain clears the air.

Does pollen in Mount Stirling 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 Mount Stirling 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 Mount Stirling, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
