Local Environmental Conditions
Located not far from here, this area has hazel and willow take root along the waterway, both prolific contributors to early pollen counts. This area, a short distance from here, has a mix of oak and birch trees, birch in particular a notorious spring allergen source. Nearby weather stations report comparable trends across the broader stretch of the county.
Water-edge hazel and willow are usually the first allergenic trees active here, arriving ahead of the rest of the season, cresting around late winter. The area's oak and birch trees pollinate through mid-to-late spring, climbing steadily through spring to a peak in April or May. Grass pollen takes over next, building to a peak around June, and then ragweed picks up the slack, running from mid-August through October.

How often is the Champlain pollen forecast updated?

Does pollen in Champlain 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 Champlain 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 Champlain, 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 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. |
