Norrköping's pollen season runs from February through August, opening with alder from February before birch peaks strongly through May. Grass follows through June and July. The Motala River valley channels airflows and concentrates pollen, while surrounding Östergötland farmland extends grass and crop pollen into August. The continental climate produces a well-defined seasonal progression with birch being particularly significant through April and May.

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.

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 Norrköping, 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.
