Local Environmental Conditions
Here, close to home here, hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen. This area, a short distance from here, has oak and birch trees, with birch pollen especially potent during its brief spring window. The broader area tends to mirror this pattern, with only minor local variation.
Hazel and willow along the water get the season underway before other species, getting an early start, typically cresting between February and March. The nearby oak and birch stands take the lead as spring progresses, cresting around April and May in the year's sharpest tree-pollen spike. Late spring brings rising grass pollen that crests in June, then yields to ragweed, the dominant late-summer and fall allergen through October.

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