The pollen calendar in Alingsås starts in February with alder, followed by a strong birch peak in May. Grass takes over from birch through the summer months of June and July. Air moving across the Säveån river and its lakes periodically clears or concentrates pollen depending on which way the wind is blowing. The tail end of the season, into August, is shaped mainly by beech forest bordering the farmland around the area.

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 Alingsås, 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.
