Ajaccio's coastal green spaces and the Gravona River corridor feature olive, pine, and maquis scrub as the main pollen sources, with exposure varying between these areas and the more built-up city centre. Surrounding Corsican maquis scrubland contributes distinctive scrub and grass pollen, while the coastal mountain setting creates varied microclimates across the Corsican capital and the hot, dry summer concentrates the season firmly in spring.

Does pollen in Ajaccio 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 Ajaccio 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 Ajaccio, 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.
