Local Environmental Conditions
Water here is bordered by hazel and willow, both notable sources of wind-borne pollen, within easy reach at 400m. Birch and oak share the canopy here, birch pollen in particular known to travel far on the wind; this sits not far off, about 300m out. Nearby, within easy reach at 200-300m, a park whose lawns and ornamental trees quietly add to grass and ragweed pollen levels.
The waterside hazel and willow are consistently first to release pollen each year, getting an early start, typically cresting between February and March. Oak and birch in the woods pick up where the earlier species leave off, usually peaking from April into May. Grass pollen builds through late spring and peaks in June, handing off to ragweed, which peaks from mid-August through October.

How often is the Struthers pollen forecast updated?
The Struthers pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Struthers 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 Struthers 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 Struthers, 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. |
