Local Environmental Conditions
The vegetation around Rugby, on flat prairie farmland at the geographic center of North America, is dominated by wheat fields and prairie grasses, with shelterbelt cottonwood adding further seasonal pollen exposure. Local parks and open ground tend to see higher pollen counts than the denser urban core. Microclimates within the area can shift the timing slightly from one neighborhood to the next.
Rugby's tree pollen season begins with elm and cottonwood from March before ash peaks during April. Grass follows, peaking through May and June, while ragweed and mugwort extend the season into September. Wide-open plains terrain lets pollen travel long distances on the prevailing wind, a defining feature of the local season.

When is pollen season in Rugby?
How often is the Rugby pollen forecast updated?
The Rugby pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Rugby 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 Rugby 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 Rugby, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
