Race day: 27 Sep 2026
Distance: 42 km

Pollen levels are today low across the route. Air quality along the route is fair. O3 (24.7/100) is fair. The remaining pollutants stay at good levels. Based on Airmine's forecast, which uses satellite data to calculate exposure every 200 metres along the route, air quality is at its worst 0.0 km after start.

Warsaw Marathon follows the Vistula River boulevard and city streets of the Polish capital, where oak, birch, and linden line the urban route. The September race date falls after the main birch and grass season, but mugwort from surrounding Mazovian farmland and the Vistula floodplain can still contribute strongly and the flat Warsaw landscape allows pollen to disperse widely throughout this autumn city marathon.

Frequently Asked Questions

Where is air quality worst on the Warsaw Marathon route?

Based on today's forecast, O3 is forecast at fair levels along the route today (24.7/100). Air quality is at its worst after 0.0 km into the route. Airmine calculates exposure at 200m intervals along the course using satellite-derived atmospheric data.

Where is pollen highest on the Warsaw Marathon course?

Pollen levels are relatively low across the entire route today. This changes through the season as different pollen species become active.

When is pollen worst during the Warsaw Marathon season?

Pollen seasons vary by location. Tree pollen (birch, alder) typically peaks in spring, while grass pollen rises in May-June.

How often is this forecast updated?

Updated four times daily. See the timestamp below for the most recent update.

Are pollen levels in Warsaw Marathon 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 Warsaw Marathon, 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.

Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.

Levels show the highest exposure along the full route. Airmine uses satellite data to calculate pollen and air quality every 200 metres along each race route, updated four times daily.
