Local Environmental Conditions
Ås in Trøndelag is a small village in Oppdal municipality near the Dovrefjell mountain range where birch, willow, and alpine meadow grasses are the main local pollen sources. The elevated mountain setting delays the season considerably compared to lowland Trøndelag, with birch peaking through May and June before grass contributes through July and the short mountain summer compresses the season significantly throughout.
For Ås, the pollen season gets underway in March and lasts through August, opening with alder and hazel beginning in March, with birch soon overtaking as the main source running through May. Grass follows close behind over June and July. With the gentle, rolling farmland typical of central Trøndelag near Ås, the local climate makes the season feel a little different here than the national average suggests.

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