Local Environmental Conditions
oak, maple, and chestnut supply most of the tree pollen across Speyer's parks and gardens, with levels varying between green space and the town centre. The Palatinate farmland and warm valley copses beyond the town supply further tree and grass pollen, while the sheltered valley setting can concentrate pollen under calm air.
Speyer's pollen season unfolds from January to August, opening with alder and hazel in January before birch peaks strongly through April and May. Grass pollen takes over across June and July. The Palatinate's vineyards and the Rhine valley around Speyer bring a warm, orchard- and vine-rich landscape, contributing orchard and vine pollen alongside the seasonal grass bloom.

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