Local Environmental Conditions
The Pas's boreal-forest setting along the Saskatchewan River features black spruce, tamarack, and muskeg wetland as dominant pollen sources at this northern Manitoba forestry and rail hub.
The Pas sits deep in Manitoba's boreal north along the Saskatchewan River, giving it a short, cool pollen season, with spruce and tamarack producing a late spring bloom and minimal grass or ragweed exposure given the surrounding forest and muskeg terrain through the brief northern summer.

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