Local Environmental Conditions
This area, within the local area, has woods composed largely of eucalypt with wattle at the margins, a combination tied to sharp late-winter pollen spikes. A green space of mown lawn and planted plane trees, both feeding into local pollen counts, not far from here. Local wind exposure and land use can shift the exact mix slightly from block to block.
Eucalypt and wattle nearby take over the pollen calendar through late winter, usually hitting its highest point sometime between mid-August and mid-September. Grass pollen climbs toward a November peak, and remaining a significant allergen right through summer until it eases in February. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

Does pollen in Greenmount 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 Greenmount 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 Greenmount, 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. |
