Karlskrona's coastal setting on the Baltic Sea and the Blekinge archipelago features birch, oak, and pine 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 Blekinge farmland and coastal woodland contribute substantial grass and tree pollen, while onshore Baltic winds can periodically disperse pollen across the island city.

Does pollen in Karlskrona 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 Karlskrona 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 Karlskrona, 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.
