Local Environmental Conditions
The riverbank shelters river oak, whose pollen spreads readily on the wind from spring onward; this sits close by. A mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia; this sits not far from here. This area, close to home here, has a park combining lawn grass and plane trees, both contributors to pollen here through the warmer months.
River oak along the water gets the season underway before other species, usually the first pollen source active, peaking sometime in July or August. Eucalypt and wattle in the woods pick up where river oak leaves off, building to its sharpest point across August and September. Spring brings rising grass pollen that crests in November, before staying elevated through the summer months into late January.

Does pollen in Mount Keira 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 Mount Keira 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 Keira, 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. |
