Neuilly-sur-Seine's Bois de Boulogne fringe is a particularly significant local tree pollen source during spring in this affluent inner Paris suburb. Hazel and alder open from January before birch and plane peak through April and May, with grass peaking through June and July. The Seine corridor channels airflows, while the urban heat island extends the season and the dry climate means fewer interruptions throughout.

The Neuilly-sur-Seine pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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 Neuilly-sur-Seine, 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.
