Local Environmental Conditions
Birkeland is a small Agder village in Birkenes municipality in the inland Aust-Agder area where birch, hazel, and boreal woodland are the main local pollen sources. The inland Agder 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 exposure into September. The relatively dry inland setting means fewer rainfall interruptions than in coastal Agder communities.
Birkeland's pollen calendar runs from February through August, with an early alder and hazel signal beginning in February, before a strong birch peak sets in continuing right through May. Grass follows close behind extending across June and July. With the coastal pine and oak woodland surrounding Birkeland, the local climate shapes a season that runs a little differently than the Norwegian average.

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