Local Environmental Conditions
Eskilstuna's parks and the Eskilstunaån River and Lake Mälaren corridor feature birch, oak, and linden as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Södermanland farmland and woodland contribute substantial grass and tree pollen, while the Lake Mälaren position means onshore lake breezes can periodically disperse urban pollen throughout the season.
Eskilstuna's pollen season runs from February through August, opening with alder from February before birch peaks strongly through May. Grass follows through June and July. The Eskilstunaån River corridor and Lake Mälaren position mean lake breezes can periodically disperse pollen, while surrounding Södermanland farmland extends substantial grass and crop pollen into August under the well-defined continental Swedish seasonal progression.

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