Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and 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 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 Tvedestrand, 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.
