Local Environmental Conditions
Borlänge relies on pine, birch, and oak in its parks and green belts as the principal tree pollen sources. Surrounding farmland and open countryside around the Dalälven river allow grass and crop pollen to disperse readily across the area. The mix of urban green space and adjacent countryside gives Borlänge a fairly typical Swedish vegetation profile for its region.
The pollen calendar in Borlänge starts in February with alder, followed by a strong birch peak in May. June and July then belong to grass pollen, which builds steadily as birch fades. The influence of the Dalälven river on local airflow is one of the more noticeable factors shaping short-term pollen swings in Borlänge. Steel and paper manufacturing in the area matters little for pollen; it is the pine forest and farmland belt that extends the season.

How often is the Borlänge pollen forecast updated?
The Borlänge pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Borlänge 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 Borlänge 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 Borlänge, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
