Local Environmental Conditions
River oak crowds the water's edge here, a well-known contributor to local casuarina pollen counts; this sits close by. Located close by, this area has woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall.
River oak by the water is typically first out of the gate, hitting its peak before most other trees flower, around July into September. The nearby eucalypt and wattle stands take the lead as winter turns to spring, topping out in the August-to-September stretch. Grass pollen builds through spring and peaks in November, with the season extending well into summer before finally winding down in February.

Does pollen in Portarlington 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 Portarlington 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 Portarlington, 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. |
