Local Environmental Conditions
Nearby, about 600-700 meters off, the riverbank shelters hazel and willow, two trees whose pollen travels readily on the breeze. Located just 250m from here, this area has woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen. Here, at a workable 450m distance, a green space where lawn grass and ornamental plantings top up the local grass and ragweed count.
Hazel and willow by the water are typically first out of the gate, reaching its high point sometime in late winter or early spring. Oak and birch in the woods pick up where the earlier species leave off, usually hitting its highest point sometime between mid-April and mid-May. Grass pollen takes over next, building to a peak around June, and then ragweed picks up the slack, running 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. |
