Local Environmental Conditions
Located not far from here, this area has eucalypt and wattle growing together, with wattle's fine pollen especially potent during its short flowering window. Here, close to home here, a park whose turf grass and ornamental plane trees feed local pollen levels through spring. The broader area tends to mirror this pattern, with only minor local variation.
For Portsea Golf Club, once river oak fades, eucalypt and wattle in the woods carry the season forward, usually hitting its highest point sometime between mid-August and mid-September. Through spring, grass pollen climbs steadily toward its November peak, before pollen counts gradually decline through January and February. Local weather swings can shift these windows slightly, but the overall order tends to hold.

Does pollen in Portsea 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 Portsea 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 Portsea, 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. |
