When is pollen season in Geneva?
From January, Plainpalais' pollen season begins with hazel and alder, followed by a birch peak through April. Oak and plane pollen build afterward, and grass takes over across June and July. Still air over the lake can let pollen linger here, while nearby vineyard slopes and farmland keep the supply flowing well into the warmer months. 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 Geneva pollen forecast updated?

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

Does pollen in Geneva 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 Geneva 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 Geneva, 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.
