Local Environmental Conditions
Årdalstangen is a small Vestland village in Årdal municipality at the innermost Sognefjord where birch, hazel, and inner fjord farmland vegetation are the main local pollen sources. The enclosed innermost Sognefjord setting concentrates pollen very effectively under calm conditions and the fjord industrial town setting limits local vegetation, while the relatively dry inner fjord microclimate means fewer rainfall interruptions than in outer fjord areas and birch peaks through April and May.
The yearly pollen cycle in Årdalstangen covers the period from March through August, with alder and hazel marking the early stage as early as March, with birch soon overtaking as the main source through May. Grass follows through June and July. With the frequent Atlantic weather systems that reach this stretch of coast, the local climate adds its own local variation on top of the general national pattern.

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

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
