Paris La Défense features linden, plane, and maple in the high-rise business district's limited planted green spaces as the main pollen sources. The Seine valley proximity means pollen from the Bois de Boulogne can reach the district under certain winds, while birch peaks through April and May and grass peaks through June and July throughout this western Paris business quarter.

Does pollen in Paris 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 Paris 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 Paris, 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.
