Local Environmental Conditions
Water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen, a short distance from here. A stand of eucalypt with wattle through the understorey, wattle ranked among the region's sharpest allergens; this sits within the neighborhood. As with most local readings, actual levels can vary somewhat with short-term weather swings.
River oak near the water opens the pollen calendar early, usually the first pollen source active, peaking sometime in July or August. Eucalypt and wattle nearby take over the pollen calendar through late winter, typically landing in August and September. Grass pollen counts rise through spring, reaching their peak around November, then holding at a high level well into January before easing off.

How often is the Strathewen pollen forecast updated?

Does pollen in Strathewen 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 Strathewen 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 Strathewen, 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. |
