Local Environmental Conditions
Tree pollen in Offenburg comes mainly from beech, spruce, and fir across parks and gardens, varying between these green areas and the denser town centre. southwestern Baden-Württemberg farmland together with upland conifer stands nearby boosts local tree and grass pollen levels, while proximity to the forest edge shelters parts of the town.
Offenburg's pollen season carries on from late January through August, kicking off with hazel and alder in early January then birch pollen dominating April into May. Grass pollen then climbs through June and July. Nearby, Black Forest woodland and Lake Constance's mild microclimate shape a distinctive regional vegetation mix, keeping mixed forest and grass pollen levels elevated into summer.

How often is the Offenburg pollen forecast updated?

Does pollen in Offenburg 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 Offenburg 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 Offenburg, 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.

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. |
