Geilo's high mountain-plateau position above the tree line for much of its surroundings means pollen exposure comes mainly from dwarf birch, willow and mountain grasses rather than lowland forest species, in a brief summer window.

When is pollen season in Geilo?
Geilo moves through a pollen season that runs its course from February to August, opening gently with alder and hazel from the start of February, before a strong birch peak sets in continuing right through May. Geilo then sees grass pollen continue across June and July. With the sheltered valleys and farmland typical of this part of eastern Norway, the local climate means conditions here can diverge a bit from the textbook national timeline.
How often is the Geilo pollen forecast updated?

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

Does pollen in Geilo 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 Geilo 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 Geilo, 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.
