Borgheim is a small Vestfold village in Nøtterøy municipality on the Nøtterøy island in the Oslofjord where birch, hazel, and coastal woodland are the main local pollen sources. The Oslofjord island position means onshore winds can periodically disperse pollen, while the mild coastal Vestfold climate advances the season slightly compared to inland eastern Norway and birch peaks through April and May before grass contributes through June and July and mugwort extends into September.

How often is the Borgheim pollen forecast updated?

Does pollen in Borgheim 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 Borgheim 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 Borgheim, 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.
