Local Environmental Conditions
The heart of Skien is heavily wooded. Close to the Skienselva River, riverside trees such as willow, poplar and alder add to local tree pollen. The allergenic tree mix nearby includes oak, alder and birch. Grasses are also a significant pollen source here. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen.
First to flower is alder, in early spring. Oak and birch follow in late spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in midsummer and keep pollen in the air into late summer. A smaller weed peak follows from midsummer into mid-fall. By mid-fall, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Skien pollen forecast updated?
The Skien pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Skien 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 Skien 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 Skien, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
