Local Environmental Conditions
Ørje is a small Østfold village in Marker municipality on the Haldenvassdraget waterway near the Swedish border where birch, hazel, and lakeside boreal woodland are the main local pollen sources. The lake and waterway setting moderates local temperatures, while the relatively dry southeastern Norwegian continental climate means fewer rainfall interruptions than in western Norway and birch peaks through April and May before grass contributes through June and July and mugwort extends into September.
Ørje's seasonal pollen activity gets underway in February and lasts through August, with alder and hazel arriving first already by February, followed by a sharp birch peak that holds through May. Ørje then sees grass pollen continue through the summer months of June and July. With the relatively mild Oslofjord-adjacent climate near Ørje, the local climate means local conditions can matter as much as the calendar month itself.

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