Local Environmental Conditions
In Red Lake State Forest, moisture-loving hazel and willow dominate the bank, both quick to release pollen on the wind, nearby. Nearby, in the vicinity, maintained parkland where turf grass and ornamental species add to the grass and ragweed mix. The broader area tends to mirror this pattern, with only minor local variation.
Around Red Lake State Forest, hazel and willow along the water get the season underway before other species, arriving ahead of the rest of the season, cresting around late winter. Grass pollen becomes the dominant allergen through late spring, peaking in June, before ragweed pollen takes center stage across mid-August into October.

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