Local Environmental Conditions
Vegetation patterns around Kajaani reflect its setting on the Kajaani river amid Kainuu forests: birch lead the tree pollen count, and grass and meadow pollen from the surrounding Kainuu countryside adds a further layer through the season. Local parks and street trees create pockets of higher exposure near the greener parts of town.
Kajaani's pollen year begins with hazel and willow in late winter, builds to a birch peak through spring, and tapers as grass and meadow pollen fades with the first summer heat; the window spans April to August. the short northern summer limits late-season pollen exposure here. Being on the Kajaani river amid Kainuu forests, Kajaani sees exposure ease once the season's main drivers pass.

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