Local Environmental Conditions
Fossbergom is a small Innlandet village in Lom municipality in the Ottadalen valley where birch, hazel, and valley farmland vegetation are the main local pollen sources. The enclosed Ottadalen valley concentrates pollen under calm conditions, while the very dry inland continental climate means minimal rainfall interruptions and birch peaks through April and May before grass from surrounding mountain farmland contributes through June and July in this dramatic Jotunheimen approaches community.
Fossbergom sees its pollen season covers the period from March through August, opening gently with alder and hazel beginning in March, with birch building to the season's sharpest peak lasting through May. Grass pollen picks up next into the following June and July. With the calmer, drier conditions typical of inland districts like this one, the local climate gives this area its own distinct rhythm within the wider Norwegian season.

How often is the Fossbergom pollen forecast updated?

Does pollen in Fossbergom 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 Fossbergom 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 Fossbergom, 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. |
