Borås' parks and the Viskan River corridor feature birch, oak, and pine as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Västergötland farmland and woodland contribute substantial tree and grass pollen, while the Atlantic-influenced climate means more frequent rainfall than in more continental Swedish cities, providing regular interruptions throughout the season.

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