Local Environmental Conditions
Estevan's Souris River valley setting features cottonwood and prairie grassland as pollen sources at this coal-and-oil city in southeastern Saskatchewan, known as the 'Energy City'.
Weyburn sits amid open grain farmland in southern Saskatchewan, giving it an intense grass and ragweed season fed by surrounding wheat and canola fields, layered onto a fairly short, sharp spring tree bloom typical of the province's dry continental prairie climate through late summer.

How often is the Estevan pollen forecast updated?

Does pollen in Estevan 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 Estevan 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 Estevan, 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
