Massy's Orge River corridor and the Forêt de Verrières fringe feature oak, plane, and linden as the main tree pollen sources, with exposure varying between these areas and the more built-up suburban landscape. As part of the greater Paris metropolitan area, surrounding Essonne farmland contributes substantial grass and crop pollen, while the Orge valley channels airflows and the Forêt de Verrières adds local tree pollen during spring.

How often is the Massy pollen forecast updated?
The Massy pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Massy 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 Massy 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 Massy, 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.
