Lying along the inner Oslofjord shore south of Oslo, Frogn 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 coastal position means onshore winds can periodically disperse pollen, while the mild coastal climate advances the season slightly compared to more inland eastern Norwegian municipalities throughout.

When is pollen season in Frogn kommune?
Across Frogn kommune, the pollen season runs its course from February to August, with an early alder and hazel signal starting around February, before birch pollen takes hold most strongly through to May. Grass pollen then carries the season through the June-July stretch. With the combination of city parkland and nearby farmland around Frogn kommune, the local climate means pollen levels here don't always follow the national pattern exactly.
How often is the Frogn kommune pollen forecast updated?

The Frogn kommune pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Frogn 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 Frogn 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 Frogn 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.
