Local Environmental Conditions
The landscape around this part of Montréal is densely built up. Maple is the most prominent allergenic tree nearby, with oak and poplar also present. Grasses are a major source, with ragweed and mugwort adding to the weed pollen load. Locally, street trees, parks and lawns are the main sources in the built-up parts.
Tree pollen peaks in mid-spring, when the weather warms to around 5°C and maple, oak and poplar are in full flower. Then come the grasses, strongest in early summer and fading by early fall. Later, ragweed and mugwort keep weed pollen in the air from late summer into mid-fall. By late fall, as temperatures fall to around freezing, pollen levels are low again.

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