Local Environmental Conditions
Stokmarknes is a small Nordland coastal town in Hadsel municipality on the Vesterålen archipelago where birch, alder, and island farmland vegetation are the main local pollen sources. The Norwegian Sea island position means onshore winds can frequently disperse pollen, while the subarctic Atlantic climate produces a compressed season with birch peaking through May before grass from surrounding Hadsel farmland contributes through June and July throughout this Vesterålen regional centre.
Stokmarknes's pollen calendar runs from March through August, with the first releases of alder and hazel from about March, with birch reaching its clearest peak that holds through June. The season then shifts to grass pollen across June and July. With the steep coastal mountains that shelter parts of Stokmarknes from the worst weather, the local climate leaves this area with a noticeably local twist on the general pattern.

Does pollen in Stokmarknes 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 Stokmarknes 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 Stokmarknes, 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. |
