Local Environmental Conditions
Umeå's parks and the Ume River corridor feature birch, pine, and alder as the main tree pollen sources, with exposure varying between green areas and the more built-up city centre. Surrounding Västernorrland boreal woodland and farmland contribute substantial tree and grass pollen, while the Gulf of Bothnia position means onshore winds can periodically disperse urban pollen across the river delta city.
Umeå's pollen season runs from March through August, starting slightly later than southern Swedish cities due to the subarctic location. Birch peaks strongly through May and June, with Umeå experiencing some of the highest birch pollen concentrations in Sweden during the intense but brief spring peak. Grass follows through June and July. The Gulf of Bothnia position means onshore winds can periodically disperse pollen across the river delta city.

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