Local Environmental Conditions
Crans-sur-Sierre Golf Club's Swiss Alpine setting at 1500 metres features larch, pine, and alpine grasses as the main pollen sources across the mountain course, with exposure varying between the open alpine meadow fairways and the more forested sections. The elevated Alpine setting means the season begins later than in lowland Swiss cities, while the Rhône valley below channels airflows and the alpine meadow grasses contribute intensely during the compressed summer season.
Crans-sur-Sierre Golf Club – Severiano Ballesteros Course's pollen timeline opens with hazel and alder in January, birch surges through April, oak and chestnut keep the tree season going, and grass takes over across June and July. The dry, sheltered Rhone valley setting can concentrate pollen under calm conditions, while surrounding orchards, vineyards, and forested slopes add substantial exposure. The sheltered, dry Rhone valley climate can extend the season slightly compared with wetter parts of Switzerland.

How often is the Crans-Montana pollen forecast updated?
The Crans-Montana pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Crans-Montana 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 Crans-Montana 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 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
