Local Environmental Conditions
Aix-les-Bains's parks and the Rhone corridor feature birch and oak as the main tree pollen sources, with exposure varying between green areas and the more built-up centre. Surrounding alpine valley pasture and orchards contribute substantial grass and scrub pollen, while local conditions tied to the alpine-continental climate affect how far pollen spreads.
Aix-les-Bains's pollen season runs from January through July, opening with hazel and alder in late winter, and progresses through birch and oak from April into May, before grass from alpine valley farmland extends the season into summer, with the alpine-continental climate of the region shaping the overall pattern.

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