Local Environmental Conditions
Lonevåg is a small Vestland village in Osterøy municipality on the Osterfjord island where birch, alder, and fjordside woodland are the main local pollen sources. The Osterfjord island position means onshore winds can periodically disperse pollen, while the very wet Atlantic western Norwegian climate provides very frequent rainfall interruptions and birch peaks through April and May before grass from surrounding Osterøy farmland contributes through June and July.
The pollen season in Lonevåg extends from March all the way through August, with alder and hazel setting things in motion around March, before birch pollen takes hold most strongly continuing right through May. From there, grass pollen continues through the June-July stretch. With the narrow, steep-sided valleys typical of this fjord district, the local climate means local conditions can matter as much as the calendar month itself.

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