Local Environmental Conditions
With no significant tree cover, water, or park mapped close by, grass growing along roadsides and open paddock likely dominates the local pollen profile. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix. As with most local readings, actual levels can vary somewhat with short-term weather swings.
Spring brings rising grass pollen that crests in November, before pollen counts gradually decline through January and February. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall. Daily pollen counts published for the wider region track this same seasonal rhythm closely. Warmer or wetter years can pull these peaks a week or two earlier or later.

Does pollen in Leeuwin 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 Leeuwin 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 Leeuwin, 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. |
