Bois de Vincennes forms the largest green space in Paris on the city's eastern edge, where oak, plane, and linden dominate this extensive former royal hunting forest now serving as an urban park. The enclosed woodland concentrates pollen under calm conditions, while birch peaks through April and May, grass through June and July, and mugwort extends into September throughout this vast eastern Paris urban forest.

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.

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.
