Trøym is a small Buskerud village in Sigdal municipality in the Numedal valley where birch, hazel, and valley woodland are the main local pollen sources. The Numedal valley concentrates pollen under calm conditions, while the inland continental Buskerud climate produces a well-defined seasonal progression with birch peaking through April and May before grass contributes through June and July and mugwort extends exposure into September throughout this small Sigdal community.

How often is the Trøym pollen forecast updated?
The Trøym pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Trøym 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 Trøym 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 Trøym, 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.
