Alta's inland fjord position gives it a more sheltered, continental character than the open coast, with birch forest along the Altaelva valley providing the main pollen source during a compressed early-summer peak.

How often is the Alta pollen forecast updated?
The Alta pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Alta 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 Alta 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 Alta, 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.
