When is pollen season in Oslo?
Oslo sees its pollen season runs its course from February to August, with an early alder and hazel signal already by February, before birch takes over with a strong peak lasting through May. Grass pollen then carries the season over June and July. With the combination of city parkland and nearby farmland around Oslo, the local climate means the season here doesn't always track the national picture precisely.
How often is the Oslo pollen forecast updated?

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

Does pollen in Oslo 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 Oslo 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 Oslo, 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.
