Local Environmental Conditions
The center of Coeur d'Alene is surrounded mainly by built-up land, with some open grassland and woodland. Standing water nearby means lakeside vegetation is part of the local pollen picture. Locally, street trees, parks and lawns are the main sources in the built-up parts. Roadside verges and patches of open ground provide further room for grasses and weeds.
Tree pollen comes first, peaking in late spring. Then come the grasses, strongest in early summer and fading by late summer. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. By late fall, as temperatures fall to around freezing, pollen levels are low again.

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