Scattered across a Skagerrak archipelago around Tvedestrand, this municipality opens the pollen season with hazel from January before birch peaks through April and May. Grass peaks through June and July before mugwort extends exposure into September. The Skagerrak island position means onshore winds can frequently disperse pollen, while the mild coastal climate advances the season and the wooded island and coastal character makes tree pollen particularly significant throughout.

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 Tvedestrand kommune based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
