When is pollen season in Liestal?
Hazel and alder kick off the season at Liestal in January, and once birch peaks strongly through April, oak and hornbeam take over before grass claims June and July. The Rhine plain setting channels prevailing winds and can concentrate pollen under calm conditions, while surrounding farmland and the Jura and Black Forest foothills add further exposure. Given the tri-border position, pollen sources here draw from farmland and forest on both sides of two frontiers.
How often is the Liestal pollen forecast updated?

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

Does pollen in Liestal 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 Liestal 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 Liestal, 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.
