Spread across the Oslofjord western shore in Greater Oslo, Asker opens the pollen season with hazel from January before birch peaks through April and May. Grass from surrounding farmland and green spaces peaks through June and July before mugwort extends exposure into September. The Oslofjord position means onshore winds can periodically disperse pollen, while the Oslo metropolitan climate slightly advances the season compared to more rural eastern Norwegian municipalities.

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 Asker 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 Asker 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.
