Local Environmental Conditions
Set at the innermost Sognefjord industrial fjord head, Årdal opens the pollen season with hazel and alder from February before birch peaks through April and May. Grass from surrounding farmland peaks through June and July before mugwort extends exposure into September. The enclosed innermost Sognefjord and industrial valley setting concentrates pollen under calm conditions, while the relatively dry inner fjord microclimate means fewer rainfall interruptions than in outer fjord areas throughout.
Årdal kommune works through a pollen season that extends from March all the way through August, starting with alder and hazel pollen in March, with birch soon overtaking as the main source running through May. Grass pollen rounds out Årdal kommune's season across June and July. With the glacier-fed valleys and heavy precipitation typical of this region, the local climate gives this area its own distinct rhythm within the wider Norwegian season.

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

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. |
