Local Environmental Conditions
Mingan Archipelago's exposed island setting features spruce, birch, and coastal grassland as the main pollen sources, with strong Gulf of St. Lawrence winds frequently dispersing pollen across these remote limestone monolith islands.
Scattered across limestone islands off the North Shore, Mingan Archipelago experiences one of the coolest, most maritime-tempered pollen seasons in Québec, with sparse island vegetation producing a late, minor spring bloom and negligible grass or ragweed presence given the archipelago's rocky, largely treeless terrain.

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