Local Environmental Conditions
Avignon's Rocher des Doms gardens and the Rhône and Durance river corridors feature olive, plane, and poplar as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Provence farmland and the Alpilles and Luberon scrubland contribute substantial grass and scrub pollen, while the Mistral wind and Rhône valley setting strongly influence pollen dispersal across the historic papal city.
Avignon's position at the Rhône and Durance confluence creates distinctive pollen dynamics, with the Mistral wind capable of rapidly dispersing or concentrating pollen depending on conditions. Olive and plane open the season from January before grass from surrounding Provence farmland peaks through April and May. The hot, dry Provençal summer ends the season abruptly, making spring the dominant pollen period.

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