When is pollen season in Lancy?
The pollen year at Lancy opens with hazel and alder in January, birch takes over through April, oak and plane carry the season forward, and grass rounds things out through June and July. Calm days let pollen build along this lakeside corridor, while nearby vineyards, farmland, and wooded foothills add a steady tree and grass supply. The lake's moderating effect means the season here tends to start a little earlier than in more elevated Swiss cities.
How often is the Lancy pollen forecast updated?

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

Does pollen in Lancy 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 Lancy 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 Lancy, 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.
