Local Environmental Conditions
This part of Quebec City is surrounded mainly by woodland, with a good deal of farmland. With the Lawrence River nearby, riverside vegetation along its banks contributes to the local mix. Woodland on all sides makes trees an important local pollen source. There is plenty of grass pollen here too.
Tree pollen comes first, peaking in late spring. Grass pollen follows, peaking in early summer and easing off by late summer. A smaller weed peak follows from early summer into early fall. Mold spores join in through summer, when damp, warm spells let them thrive. By late fall, as temperatures fall to a few degrees below freezing, pollen levels are low again.

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