Local Environmental Conditions
Water here is bordered by hazel and willow, both notable sources of wind-borne pollen; this sits within 100-200m of this spot. Here, a short trip out, around 400-500m, oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two.
Near the bank, hazel and willow lead the seasonal calendar, climbing steadily from late winter into March. Oak and birch nearby take over the pollen calendar through mid-spring, usually hitting its highest point sometime between mid-April and mid-May. Grass pollen becomes the dominant allergen through late spring, peaking in June, with ragweed then rising to the fore from mid-August through October.

Does pollen in Steubenville 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 Steubenville 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 Steubenville, 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. |
