Local Environmental Conditions
Lying in the remote Vefsna valley of inland Nordland, Grane opens the pollen season with alder from March before birch peaks through May. Grass from surrounding farmland peaks through June and July, while the enclosed valley concentrates pollen under calm conditions and the subarctic continental setting means the season is more compressed than in coastal Nordland municipalities with the season ending earlier in autumn.
The annual pollen season around Grane kommune spans March through August, led in by alder and hazel from the start of March, with birch then climbing to its main peak continuing right through June. Grass follows through the June-July stretch. With the strong coastal airflow common to this part of northern Norway, the local climate makes the season feel a little different here than the national average suggests.

How often is the Grane kommune pollen forecast updated?
The Grane kommune pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Grane 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 Grane 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 Grane 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
