Horsens' streets and the parkland around Bygholm Lake are shaded mainly by oak and ash, with birch common in the newer residential areas. East Jutland's rolling farmland presses in close to the town on almost every side, feeding a strong grass and cereal pollen load each summer that the fjord's onshore breeze only partially offsets.

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