Local Environmental Conditions
Drancy's urban green spaces and canal corridors feature plane, oak, and linden as the main tree pollen sources, with exposure varying between these areas and the densely built suburban landscape. As part of inner north Paris, local sources dominate, while the nearby Forêt de Bondy and surrounding Seine-Saint-Denis farmland contribute additional tree and grass pollen under prevailing westerly winds.
Drancy's inner north Paris position means the urban heat island extends the season at both ends. Hazel and alder open from January before birch and plane peak through April and May, with grass peaking through June and July. The nearby Forêt de Bondy contributes locally significant tree pollen during spring, while surrounding Seine-Saint-Denis farmland extends grass exposure into August.

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