Parc Astérix sits north of Paris in the Oise valley, surrounded by the Ermenonville forest where oak, birch, and Scots pine are the main pollen sources around this theme park setting. The forest contributes substantial tree pollen, while birch peaks intensely through April and May, grass from surrounding farmland contributes through June and July, and mugwort extends into September throughout this Oise valley theme park.

The Paris 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 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.
