Local Environmental Conditions
At East Grand Forks, hazel and willow crowd the water's edge, both classic sources of early allergenic pollen; this sits within the neighborhood. Nearby, within the neighborhood's edge, a park where mown turf grass and ornamental trees add grass and ragweed pollen. Local microclimate and soil conditions can push these figures slightly higher or lower.
At East Grand Forks, hazel and willow near the water open the pollen calendar early, getting an early start, typically cresting between February and March. Grass pollen builds through late spring and peaks in June, before ragweed's late-summer surge carries the season into October. Year-to-year timing varies a little, though the general sequence stays fairly consistent here.

Does pollen in East Grand Forks 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 East Grand Forks 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 East Grand Forks, 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. |
