Local Environmental Conditions
Rødberg is a small Buskerud village in Numedal municipality in the upper Numedal valley where birch, hazel, and valley woodland are the main local pollen sources. The upper Numedal valley concentrates pollen under calm conditions, while the inland continental Buskerud 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 throughout.
The yearly pollen cycle in Rødberg stretches from February through August, with an early alder and hazel signal from about February, with birch then climbing to its main peak into May. Rødberg then sees grass pollen continue across June and July. With the sheltered valleys and farmland typical of this part of eastern Norway, the local climate plays a bigger role in the local pollen pattern than the calendar alone.

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