Located just around the area, this area has this patch of forest is largely oak and birch, a pairing known for heavy spring pollen output. Seasonal timing here generally tracks the wider region, give or take a week or so.
At Kenyon, oak and birch nearby take over the pollen calendar through mid-spring, reaching maximum intensity across the April-May window. The bank's hazel and willow kick off the pollen season ahead of the rest, starting well before the main spring rush, topping out around March. Grass pollen rises through late spring toward a June high point, before ragweed takes over as the dominant allergen from mid-August through October.

How often is the Kenyon pollen forecast updated?

Does pollen in Kenyon 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 Kenyon 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 Kenyon, 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. |
