Local Environmental Conditions
Here, in the wider area, hazel and willow cluster near the water, an early and reliable source of allergenic pollen. Nearby, within the local area, forest where oak and birch make up much of the canopy, driving spring pollen counts. This area, near this part of town, has a park combining lawn grass and planted trees, both minor but real contributors to pollen here.
Hazel and willow near the water open the pollen calendar early, arriving ahead of the rest of the season, cresting around late winter. By mid-spring, oak and birch in the woods take over, topping out in the April-to-May stretch. Grass pollen rises through late spring toward a June high point, with ragweed then rising to the fore from mid-August through October.

Does pollen in Central Elgin 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 Central Elgin 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 Central Elgin, 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. |
