Local Environmental Conditions
This location in Sarnen is surrounded mainly by snow and ice, with a good deal of bare ground. Common allergenic trees in the wider area include alder, willow and maple. Grasses and plantain growing in the surroundings are the main non-tree sources of pollen. Local vegetation is sparse, so most pollen arrives on the wind from surrounding land.
First to flower is alder, in early spring. Willow and maple follow in mid-spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Grasses take over in early summer and keep pollen in the air into early fall. The season closes with plantain from late spring into late summer. In warm, humid weather through summer, mold spores add to the mix, especially after rain.

How often is the Sarnen pollen forecast updated?
The Sarnen pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Sarnen 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 Sarnen 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 Sarnen, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
