Otta is a small Innlandet town in Sel municipality at the confluence of the Otta and Gudbrandsdalslågen rivers where birch, hazel, and valley farmland vegetation are the main local pollen sources. The Gudbrandsdalen valley concentrates pollen under calm conditions, while the inland continental climate produces a well-defined seasonal progression with birch peaking through April and May before grass contributes through June and July and mugwort extends into September.

How often is the Otta pollen forecast updated?

Does pollen in Otta 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 Otta 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 Otta, 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.
