How to connect?

Reaching up to the Hardangervidda plateau in the uppermost Hallingdal valley, Hol opens the pollen season with birch from April before grass from surrounding mountain farmland peaks through June and July. The elevated mountain and plateau setting means the season begins considerably later than in lowland Buskerud, while the enclosed upper valley concentrates pollen under calm conditions and mugwort extends exposure into September throughout.

Does pollen in Hol kommune 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 Hol kommune 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 Hol kommune, 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.
