Local Environmental Conditions
Around Deggendorf, hornbeam, maple, and oak stand out as the leading tree pollen sources in parks and gardens, with exposure shifting between green space and centre. Farmland across the Franconian and mixed oak forest nearby contribute additional tree and grass pollen, while the valley floor can concentrate pollen under calm conditions.
Deggendorf's pollen season runs from January into August, starting with alder and hazel from January before birch peaks strongly through April and May. Grass pollen then climbs through June and July. The Franconian countryside around Deggendorf mixes river valleys, farmland, and pine or oak woodland, keeping tree and grass pollen levels elevated through June.

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