Local Environmental Conditions
Berkåk is a small Trøndelag village in Rennebu municipality in the Orkla valley where birch, alder, and valley farmland vegetation are the main local pollen sources. The Orkla valley concentrates pollen under calm conditions, while the Atlantic-influenced but inland Trøndelag climate produces a well-defined seasonal progression with birch peaking through April and May before grass contributes through June and July throughout this Dovrefjell approaches community.
Berkåk typically experiences a pollen season that spans March through August, with an early alder and hazel signal around March, with birch building to the season's sharpest peak which carries through May. Grass pollen rounds out Berkåk's season and holds through June and July. With the mix of farmland and forest around Berkåk, the local climate means the timing can vary from what neighbouring districts experience.

How often is the Berkåk pollen forecast updated?

Does pollen in Berkåk 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 Berkåk 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 Berkåk, 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. |
