Local Environmental Conditions
oak, birch, and maple make up the bulk of tree pollen sources across Osnabrück's parks and gardens, though the built-up centre sees noticeably less. Lower Saxon farmland and ridge-line beech stands on the town's outskirts add to local tree and grass pollen, while valley settings can concentrate pollen under calm, still air.
Osnabrück's pollen season carries on from January to August, beginning with hazel and alder in January with birch peaking through April and May. Grass pollen follows, dominating June and July. It lies within the inland Lower Saxon countryside, where farmland gives way to Harz foothill woodland nearby, adding beech woodland pollen alongside the seasonal grass bloom.

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