On 16 July 2026, Grass is the dominant pollen source in Montreux. birch, hazel, cypress, willow, alder, and artemisia are not currently active.

Montreux's pollen timeline opens with hazel and alder in January, birch surges through April, oak and plane keep the tree season going, and grass takes over across June and July. The lake and its ring of hills shape local airflow, occasionally concentrating pollen on windless days, while surrounding vineyard country extends the season's exposure. The lake's moderating effect means the season here tends to start a little earlier than in more elevated Swiss cities.

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

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.

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 Montreux, 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.
