Local Environmental Conditions
Most of the area around Crowsnest Pass is woodland, with a good deal of open grassland. So much tree cover makes trees an important source of pollen locally. Grasses add a sizeable share of the local pollen. Roadside verges and patches of open ground provide further room for grasses and weeds.
Tree pollen comes first, peaking in late spring. Grasses take over in midsummer, with temperatures around 15°C, and their pollen lingers into late summer. A smaller weed peak follows from midsummer into mid-fall. By mid-fall, as temperatures fall to around 5°C, pollen levels are low again. Weather shapes each of these periods: dry, windy spells drive levels up, and showers wash pollen out of the air.

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