Local Environmental Conditions
In Viroqua, maintained parkland where turf grass and ornamental species add to the grass and ragweed mix; this sits nearby. The broader area tends to mirror this pattern, with only minor local variation. Seasonal timing here generally tracks the wider region, give or take a week or so. Surrounding neighborhoods with similar tree cover typically see a closely comparable pollen mix.
For Viroqua, grass pollen climbs toward a June peak, before ragweed becomes the more dominant allergen from mid-August into October. The overall order of species tends to hold steady, even as exact dates shift slightly each year. Regional pollen monitoring generally reflects this same pattern across nearby areas. Small variations in local weather can nudge these windows a few days in either direction.

When is pollen season in Viroqua?
How often is the Viroqua pollen forecast updated?
The Viroqua pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Viroqua 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 Viroqua 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 Viroqua, 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
