Seinäjoki's parks and the Kyrönjoki River corridor feature birch, pine, and alder as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Ostrobothnia farmland and woodland contribute substantial tree and grass pollen, while the flat, open landscape allows pollen to disperse readily across the city and birch is particularly significant during the Finnish spring peak.

Grass follows through June and July, while surrounding Ostrobothnia farmland contributes substantial grass pollen. Birch is particularly significant during the intense Finnish spring peak period.
How often is the Seinäjoki pollen forecast updated?

The Seinäjoki pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Seinäjoki 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 Seinäjoki 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 Seinäjoki, 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.
