Trier's parks and the Moselle River corridor feature oak, birch, and plane as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Rhineland vineyard farmland and the Eifel and Hunsrück woodland contribute substantial tree and grass pollen, while the warm Moselle valley microclimate extends the pollen season compared to surrounding upland areas.

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