Local Environmental Conditions
Nearby, just outside the immediate area, a stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months. Here, close by, parkland with regularly mown grass and planted plane trees, both sources of seasonal pollen. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
The water-adjacent river oak is an early riser, usually the first pollen source active, peaking sometime in July or August. Grass pollen counts rise through spring, reaching their peak around November, before continuing at a lower but still notable level through January and February. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

Does pollen in Katanning 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 Katanning 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 Katanning, 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. |
