Local Environmental Conditions
In Red Lake, hazel and willow grow along the local waterway, both efficient wind pollinators. Red Lake has a nearby park keeps grass and ragweed counts ticking over with regularly mown lawns. Neighboring areas with similar tree cover see a similar mix.
Hazel and willow by the water go first each year, peaking around March. Grass pollen rises steadily, cresting in June, and ragweed follows from mid-August into October. This pattern tends to hold across the wider region each year.

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