Vitry-sur-Seine's Seine valley position in inner south Paris connects the city to the broader metropolitan pollen landscape. Hazel and alder open from January before birch and plane peak through April and May, with grass peaking through June and July. The urban heat island extends the season at both ends, while the dry Île-de-France climate means fewer rainfall interruptions than in Atlantic-facing French cities.

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 Vitry-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.
