Local Environmental Conditions
A stretch of hazel and willow lines the water, feeding some of spring's earliest pollen; this sits within the neighborhood's edge. A nearby park's turf and ornamental trees layer grass and ragweed pollen onto the seasonal mix, nearby. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
The waterside hazel and willow are consistently first to release pollen each year, climbing steadily from late winter into March. Grass pollen takes over next, building to a peak around June, then gives way to ragweed, which drives the season's second major surge from mid-August into October. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

How often is the Crookston pollen forecast updated?

Does pollen in Crookston 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 Crookston 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 Crookston, 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. |
