Local Environmental Conditions
Alder, willow, and cottonwood lining the riverbanks are the main pollen sources through central Munich, alongside the English Garden just upstream. Calm river-valley air concentrates pollen locally; birch peaks through April and May, riverside meadows add grass pollen through June and July, and mugwort lingers into September along this central corridor.
Through central Munich, the Isar corridor carries alder, willow, and cottonwood along its banks as the leading pollen sources, alongside the English Garden just upstream. Calm river-valley air concentrates pollen locally; birch peaks through April and May, riverside meadows add grass pollen through June and July, and mugwort lingers into September along this central river route.

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