This area, close to this spot, has a mix of oak and birch trees, birch in particular a notorious spring allergen source. Nearby, just around the area, green space with maintained lawn and planted trees, both contributing to grass and ragweed counts.
For Faribault County Fairgrounds, once hazel fades, oak and birch in the woods carry the season forward, generally peaking somewhere between April and May. Grass pollen becomes the dominant allergen through late spring, peaking in June, before ragweed becomes the more dominant allergen from mid-August into October. Local weather swings can shift these windows slightly, but the overall order tends to hold.

How often is the Blue Earth pollen forecast updated?
The Blue Earth pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Blue Earth 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 Blue Earth 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 Blue Earth, 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. |
