Local Environmental Conditions
The area around the heart of Coaticook is a mix of woodland and built-up land, plus some open grassland. Locally, the surrounding woods make trees an important source. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Flowering trees bring the first pollen of the year in late spring. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. Weeds on open ground add a smaller late peak from early summer into early fall. Mold spores join in through summer, when damp, warm spells let them thrive.

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