Local Environmental Conditions
Gävle's coastal setting on the Gulf of Bothnia features birch, pine, and alder as the main tree pollen sources in parks and along streets, with exposure varying between green areas and the more built-up city centre. Surrounding Gästrikland boreal woodland and farmland contribute substantial tree and grass pollen, while the coastal position means onshore winds can periodically disperse pollen across the river delta city.
Gävle's pollen season runs from March through August, starting slightly later than southern Swedish cities due to the northerly Gulf of Bothnia coastal location. Birch peaks strongly through May, with onshore coastal winds periodically dispersing pollen. Grass follows through June and July, while surrounding Gästrikland boreal woodland contributes substantial tree pollen. The season is shorter and more compressed than in southern Sweden.

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