How to connect?

Athens' urban vegetation, anchored by the National Garden and the Kifissos River corridor, features pine, olive, and cypress as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Attica peninsula scrubland and the Hymettus and Parnitha mountain woodland contribute substantial grass and tree pollen, while the hot, dry Mediterranean climate concentrates pollen dispersal during the spring season.

When is pollen season in Athens?
Athens' pollen season runs from February through June, opening with cypress and olive tree pollen in late winter and early spring. Grass pollen from surrounding Attica farmland peaks through April and May. The hot, dry Mediterranean climate means the season ends abruptly as summer heat and drought suppress vegetation, making Athens' pollen season shorter but more intense during its peak weeks than in northern European cities.
How often is the Athens pollen forecast updated?

The Athens pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Athens 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 Athens 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 Athens, 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.
