Local Environmental Conditions
Here, in the surrounding area, a wooded stretch of oak and birch, with birch responsible for some of the sharpest spring counts. A park whose lawns and ornamental trees quietly add to grass and ragweed pollen levels; this sits in the wider area. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
As spring advances, oak and birch in the nearby woodland become the dominant source, climbing steadily through spring to a peak in April or May. As spring turns to summer, grass pollen rises toward its June high, handing off to ragweed, which peaks from mid-August through October. Warmer or wetter years can pull these peaks a week or two earlier or later.

How often is the Windsor pollen forecast updated?

Does pollen in Windsor 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 Windsor 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 Windsor, 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
