In Sendenhorst, birch, beech, and oak dominate the parks and street trees as primary pollen sources, with levels differing between green space and the built-up core. Westphalian farmland together with isolated copses nearby boosts local tree and grass pollen levels, while the level countryside allows pollen to spread widely across the town.

How often is the Sendenhorst pollen forecast updated?

Does pollen in Sendenhorst 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 Sendenhorst 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 Sendenhorst, 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.
