Royan's tree cover, concentrated in parks and along the Charente, is dominated by oak and plane. The vineyard land and the Landes pine forest nearby are a major source of grass pollen later in the season, while local conditions tied to the oceanic-continental climate affect how far pollen spreads.

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