Located on the Adriatic coast of Slovenia's short coastline, Koper in Obalno-kraška draws most of its tree pollen from spruce and birch, while grass and alpine meadow pollen contributes further exposure as the season progresses. Green spaces close to the built-up centre see noticeably different totals than the more open outskirts nearby, where surrounding farmland and woodland add their own seasonal contribution to the mix.

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