Local Environmental Conditions
Spread along the Oslofjord shore south of Oslo, Moss opens the pollen season with hazel from January before birch peaks through April and May. Grass from surrounding farmland peaks through June and July before mugwort extends exposure into September. The Oslofjord position means onshore winds can periodically disperse pollen, while the relatively dry southeastern Norwegian climate means fewer rainfall interruptions than in western Norway throughout.
Moss kommune's pollen calendar is bookended by February and August, with alder and hazel arriving first from the start of February, with birch soon overtaking as the main source into May. Grass follows close behind into the following June and July. With the fertile lowlands of eastern Norway around Moss kommune, the local climate gives this particular area its own seasonal quirks worth knowing about.

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