On 9 August 2026, Artemisia is the dominant pollen source in Ostrava. grass are also present but at lower levels. willow, hazel, and cypress are not currently active.

Ostrava follows the typical Central European pattern: hazel and alder first, then oak and birch through spring, then grass into early summer, running February to August overall. Late-summer mugwort and ragweed can extend exposure into September in more open, farmed surroundings.

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

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.

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 Ostrava, 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.
