Local Environmental Conditions
Here, not far from here, river oak thrives along the damp bank, a classic riparian wind-pollinator in this part of Australia. Nearby, just outside the immediate area, eucalypt and wattle growing together, with wattle's fine pollen especially potent during its short flowering window. The broader area tends to mirror this pattern, with only minor local variation.
The bank's river oak kicks off the pollen season ahead of the rest, usually the first pollen source active, peaking sometime in July or August. Further into late winter, the area's eucalypt and wattle stands drive the pollen count, topping out in the August-to-September stretch. Grass pollen builds through spring and peaks in November, before staying elevated through the summer months into late January.

Does pollen in Mount Royal 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 Royal 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 Royal, 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. |
