Pollen and allergies — Olsztyn
Olsztyn lies in Warmińsko-Mazurskie, on the Łyna river at the edge of the Masurian lake district. The area around the city is marked by lakes, pine and birch forests, and wetlands, which moderate temperature swings and shape the pollen season. The cooler north-eastern Polish climate means grasses linger here longer than in other regions.
Main allergens and season
- March–April: hazel and alder, followed by birch in the surrounding forests.
- April–May: birch, oak, and ash.
- May–July: grasses on meadows, clearings, and roadsides — the season stretches out thanks to moisture from nearby lakes and marshes.
- August–September: mugwort and ragweed on unmown plots and near roads.
The forecast uses the European CAMS model through Open-Meteo. Levels are modeled, not measured at a local station within this service, so they are orientative.
