Local Environmental Conditions
Athens' urban vegetation, anchored by the National Garden and the Kifissos River corridor olive and cypress dominate locally, and grass from nearby Attikí farmland extends exposure into spring. Hot, dry summer conditions then suppress pollen production for months.
Athens's pollen season runs from February through June, opening with olive and cypress in late winter before grass from local farmland peaks through spring. The hot, dry Mediterranean summer brings the season to an abrupt close. Exposure tends to be sharper and shorter-lived than in more temperate parts of Europe.

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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
