Tucked into the Telemark interior in the Numedal valley tributary, Hjartdal 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 enclosed Telemark valley concentrates pollen under calm conditions, while the inland continental climate produces a well-defined seasonal progression throughout.

Does pollen in Hjartdal kommune come from nearby or far away?

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 Hjartdal 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 Hjartdal 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.
