Local Environmental Conditions
Ølen is a small Rogaland village in Vindafjord municipality on the inner Ølsfjord where birch, alder, and fjordside farmland vegetation are the main local pollen sources. The fjord position means onshore winds can periodically disperse pollen, while the Atlantic-influenced Rogaland climate provides frequent rainfall interruptions and birch peaks through April and May before grass from surrounding Vindafjord farmland contributes through June and July throughout.
Ølen's seasonal pollen activity extends from February all the way through August, starting quietly with alder and hazel from the start of February, before the season's main birch surge arrives before easing after May. Grass pollen extends the season and holds through June and July. With the open coastal plains near Ølen, the local climate means residents often notice a slightly different pattern than official averages suggest.

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