Crans-Montana's pollen year begins in January with hazel and alder, moves into a birch peak through April, adds oak and chestnut, and culminates in a grass peak across June and July. Calm, dry air here can let pollen settle in the valley, while surrounding orchards, vineyards, and wooded slopes add a steady tree and grass supply. The sheltered, dry Rhone valley climate can extend the season slightly compared with wetter parts of Switzerland.

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 Crans-Montana, 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.
