Gennevilliers' Seine River loop and the Grand Gabarit canal corridor feature plane, oak, and linden as the main tree pollen sources, with exposure varying between these areas and the densely built industrial city centre. As part of inner north Paris, local sources dominate, while the Seine loop channels airflows and surrounding Île-de-France farmland and the Gennevilliers plain contribute additional grass and crop pollen.

Does pollen in Gennevilliers 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 Gennevilliers 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 Gennevilliers, 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.
