Local Environmental Conditions
Perpignan's riverside green spaces and the Têt and Basse river corridors feature olive, plane, and palm as the main tree pollen sources, with exposure varying between these areas and the more built-up city centre. Surrounding Roussillon farmland, orchards, and vineyards contribute substantial grass and crop pollen, while the enclosed Roussillon plain concentrates pollen under calm conditions and the Tramontane wind can rapidly disperse pollen under offshore conditions.
Perpignan has one of the earliest and most intense spring pollen seasons in France, with olive and plane opening from January and grass from surrounding Roussillon farmland and orchards peaking through March and April. The hot, dry summer ends the season very abruptly, while the Tramontane wind can rapidly disperse or concentrate pollen depending on conditions across the enclosed Roussillon plain.

How often is the Perpignan pollen forecast updated?

Does pollen in Perpignan 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 Perpignan 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 Perpignan, 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. |
