ash, maple, and hornbeam supply most of the tree pollen across Werl's parks and gardens, with levels varying between green space and the town centre. Nearby Westphalian farmland along with field-edge tree lines add tree and grass pollen through the season, while the level countryside allows pollen to spread widely across the town.

When is pollen season in Werl?
Werl's pollen season spans January through August, starting with hazel and alder in January then birch peaks strongly through April and May. Grass pollen then peaks through June and July. The gently rolling farmland around Werl in the Westphalian plain provides little topographic shelter from regional pollen drift, keeping grass pollen levels elevated through the summer cropping season.
How often is the Werl pollen forecast updated?

The Werl pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Werl 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 Werl 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 Werl, 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.
