Local Environmental Conditions
Solakrossen is a small Rogaland suburban village in Sola municipality on the Jæren coast near Stavanger airport where birch, hazel, and coastal farmland vegetation are the main local pollen sources. The North Sea coastal position means onshore winds can frequently disperse pollen, while the mild Atlantic Rogaland climate advances the season and birch peaks through April and May before grass from surrounding Jæren farmland contributes strongly through June and July and mugwort extends into September.
Solakrossen's pollen season typically lasts from February through August, opening with alder and hazel as early as February, before birch pollen takes hold most strongly into May. Grass follows over June and July. With the open coastal plains near Solakrossen, the local climate adds its own local variation on top of the general national pattern.

Does pollen in Solakrossen 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 Solakrossen 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 Solakrossen, 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. |
