Local Environmental Conditions
Built-up land and woodland share the area around the heart of Smithers, plus some open grassland. Allergenic trees nearby include poplar. Grasses add a sizeable share of the local pollen. In the immediate area, street trees, parks and lawns are the main sources in the built-up parts. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Poplar leads the season in mid-spring, bringing the main tree pollen peak. Grasses take over in early summer, with temperatures around 10°C, and their pollen lingers into late summer. Weeds on open ground add a smaller late peak from midsummer into mid-fall. By mid-fall, as temperatures fall to around freezing, pollen levels are low again.

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