Local Environmental Conditions
Woodland makes up around 47% of the area near the center of Dollard-des-Ormeaux, with a good deal of built-up land. Of the allergenic trees nearby, maple matters most, while pecan and oak also contribute. Ragweed is the main local weed pollen source. Compared with most places, ragweed is especially widespread here, which makes it one of the key local allergens.
Tree pollen peaks in mid-spring, when the weather warms to around 5°C and maple, pecan and oak are in full flower. Ragweed brings the strongest peak of the year from late summer into mid-fall. By late fall, as temperatures fall to around freezing, pollen levels are low again. Within each of these periods, warm, dry and windy days push levels higher, while rain clears the air.

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