Local Environmental Conditions
Dübendorf's Glatt valley setting features oak, ash, and linden as pollen sources, with exposure varying between the Glatt riverside greenery and the built-up aviation and technology district. Surrounding farmland extends grass pollen through summer.
The pollen year at Dübendorf opens with hazel and alder in January, birch takes over strongly through April, ash and oak carry the season forward, and grass rounds things out through June and July. The lake setting and surrounding hills channel airflows and can concentrate pollen under calm conditions, while nearby farmland and orchards add further exposure.

How often is the Dübendorf pollen forecast updated?
The Dübendorf pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Dübendorf 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 Dübendorf 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 Dübendorf, 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. |
