Spread across the flat Romerike plain near Oslo Airport, Ullensaker opens the pollen season with hazel from January before birch peaks through April and May. Grass from surrounding farmland peaks strongly through June and July before mugwort extends exposure into September. The flat open Romerike agricultural plain allows pollen to disperse very widely, while the continental climate means fewer rainfall interruptions than in western Norway throughout.

Does pollen in Ullensaker 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 Ullensaker 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 Ullensaker 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.
