Local Environmental Conditions
Invermere's Columbia Valley setting on Windermere Lake features Douglas fir, ponderosa pine, and wetland vegetation as pollen sources beneath the Purcell Mountains.
Sitting in the Columbia Valley beneath the Rocky and Purcell ranges, Invermere experiences a cooler, mountain-lake pollen season, with conifer forest producing a delayed spring bloom, while the valley's dry summer air and nearby lake sustain a fairly light, short grass pollen season.

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