Local Environmental Conditions
Eucalypt and wattle growing together, with wattle's fine pollen especially potent during its short flowering window; this sits close to this spot. As with most local readings, actual levels can vary somewhat with short-term weather swings. The general pattern described here holds fairly steady across nearby areas with similar land cover.
Eucalypt and wattle in the woods pick up where river oak leaves off, building to its sharpest point across August and September. Grass pollen climbs toward a November peak, with levels staying elevated into the new year before finally easing off. Year-to-year timing varies a little, though the general sequence stays fairly consistent here.

Does pollen in Upper Macdonald 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 Upper Macdonald 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 Upper Macdonald, 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. |
