Local Environmental Conditions
Stavanger's coastal setting on the Stavanger fjord features birch, alder, and pine as the main tree pollen sources in parks and along streets, with exposure varying between green areas and the more built-up city centre. Surrounding Rogaland farmland and coastal heathland contribute substantial tree and grass pollen, while the Atlantic-facing position means frequent rainfall provides regular interruptions to exposure throughout the season.
Stavanger typically experiences a pollen season that stretches from February through August, with an early alder and hazel signal from about February, before birch surges to its highest levels which carries through May. Grass pollen then carries the season through the June-July stretch. With the open coastal plains near Stavanger, the local climate means pollen levels here don't always follow the national pattern exactly.

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