Local Environmental Conditions
fir, spruce, and oak supply most of the tree pollen across Lahr's parks and gardens, with levels varying between green space and the town centre. Farmland across the southwestern Baden-Württemberg and Black Forest conifer stands nearby contribute additional tree and grass pollen, while the forested uplands moderate local airflow and pollen spread.
Lahr's pollen season carries on from January to August, starting with alder and hazel already active by January then birch peaking through April and May. Grass pollen then climbs through June and July. The southwestern uplands near Lahr combine Black Forest conifer stands with Rhine valley farmland, contributing steady conifer pollen alongside the seasonal grass bloom.

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