Local Environmental Conditions
Spread across the agricultural and woodland landscape of eastern Østfold, Indre Østfold 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 Glomma River corridor concentrates pollen under certain conditions, while the relatively dry continental southeastern climate means fewer rainfall interruptions than in western Norway throughout.
Indre Østfold kommune works through a pollen season that spans February through August, beginning with alder and hazel picking up from February, before a strong birch peak sets in continuing right through May. Grass follows through the June-July stretch. With the relatively mild Oslofjord-adjacent climate near Indre Østfold kommune, the local climate leaves this area with a noticeably local twist on the general pattern.

How often is the Indre Østfold kommune pollen forecast updated?

Does pollen in Indre Østfold 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 Indre Østfold 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 Indre Østfold 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. |
