Local Environmental Conditions
Open water makes up around 41% of the area near the heart of Elkhorn, with some woodland and open grassland. Close to running water, riverside vegetation contributes to what is in the air. Oak is the most prominent allergenic tree nearby. Grass pollen is plentiful, while mugwort and pigweed lead among the weeds.
Oak leads the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in midsummer, with temperatures around 20°C, and their pollen lingers into early fall. The season closes with mugwort and pigweed through summer. Rain is heaviest in winter, often giving short breaks from high pollen levels.

How often is the Elkhorn pollen forecast updated?
The Elkhorn pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Elkhorn 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 Elkhorn 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 Elkhorn, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
