Montreuil's urban green spaces and street tree corridors feature plane, oak, and linden as the main tree pollen sources, with exposure varying between these areas and the densely built urban centre. As part of the greater Paris metropolitan area, local sources dominate, while surrounding Île-de-France farmland contributes additional grass and tree pollen under prevailing westerly winds throughout the season.

Hazel and alder open from January before birch and plane peak through April and May, with grass peaking through June and July. Surrounding Île-de-France farmland contributes additional grass and tree pollen, while the dry regional climate means fewer rainfall interruptions than in Atlantic-facing French cities.
How often is the Montreuil pollen forecast updated?

Does pollen in Montreuil 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 Montreuil 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 Montreuil, 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.
