Local Environmental Conditions
Nearby, close by, the waterway's edge supports river oak, a species whose fine pollen travels well beyond the immediate bank. Nearby, close to home here, woodland dominated by eucalypt and wattle, with wattle the more potent allergen of the two. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
The water-adjacent river oak is an early riser, getting an early start, typically cresting between July and August. The area's eucalypt and wattle trees pollinate through late winter and early spring, cresting around August and September in the year's sharpest tree-pollen spike. 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 Osmington pollen forecast updated?

Does pollen in Osmington 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 Osmington 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 Osmington, 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. |
