Local Environmental Conditions
Tree cover in Piteå is dominated by pine, birch, and oak, concentrated in parks and along the water's edge rather than in the city centre. Grass and crop pollen travel easily across the flat, open land bordering the Bothnian Bay coastline. The mix of urban green space and adjacent countryside gives Piteå a fairly typical Swedish vegetation profile for its region.
Piteå sees a delayed but intense pollen season, starting with alder in March and building to a compact birch peak by June. By early summer, grass pollen becomes the dominant driver through June and into July. The proximity to the Bothnian Bay coastline means local wind patterns can periodically disperse or concentrate pollen levels. The tail end of the season, into August, is shaped mainly by pine forest bordering the farmland around the area.

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