Opava's Opava River valley and the Opava Highlands woodland fringe feature oak, birch, and linden as the main tree pollen sources in this historic Silesian city. Surrounding farmland and the upland woodland contribute substantial tree and grass pollen, while the Opava valley channels airflows and the continental climate produces a well-defined spring pollen season throughout.

How often is the Opava pollen forecast updated?

Does pollen in Opava 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 Opava 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 Opava, 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.
