Local Environmental Conditions
Solna's tree pollen comes mainly from birch, birch, and oak growing in parks and along residential streets rather than the compact centre. Farmland close to the Hagaparken royal woodland nearby adds a steady stream of grass and crop pollen through the growing season. Life sciences and media industry plays little role in vegetation-driven pollen here, which is shaped instead by the surrounding countryside.
The pollen calendar in Solna starts in February with alder, followed by a strong birch peak in May. Grass pollen then dominates for several weeks in June and July before gradually easing. Air moving across the Hagaparken royal woodland nearby periodically clears or concentrates pollen depending on which way the wind is blowing. Life sciences and media industry activity in the area has little direct bearing on pollen levels, which instead track the regional birch and farmland cover.

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