Local Environmental Conditions
Nearby, nearby, hazel and willow take root along the waterway, both prolific contributors to early pollen counts. This area, in the surrounding area, has oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
Hazel and willow near the water open the pollen calendar early, getting an early start, typically cresting between February and March. Further into spring, the area's oak and birch stands drive the pollen count, generally peaking somewhere between April and May. Moving into early summer, grass pollen climbs to its seasonal high in June, before ragweed pollen takes center stage across mid-August into October.

Does pollen in Duquesne 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 Duquesne 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 Duquesne, 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. |
