Local Environmental Conditions
This area, at a workable 600-700m distance, has the riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze. Here, close enough to matter, at 100m, woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen. The park's turf and planted trees form a small but steady source of grass and ragweed pollen; this sits some 400-500 meters out.
Water-edge hazel and willow are usually the first allergenic trees active here, usually peaking sometime between late winter and the end of March. Oak and birch in the nearby woodland follow in mid-to-late spring, climbing steadily through spring to a peak in April or May. Grass pollen counts rise through late spring, reaching their peak around June, followed by ragweed's own peak stretch from mid-August into 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. |
