Pollen and allergies — Warszawa
Warsaw lies in the Vistula valley, between dense urban areas and large green spaces such as Bielany Forest, Kabaty Forest, parks, and riverfront land. This setting makes the pollen season long and variable by district: trees dominate in spring, followed by grasses and weeds on vacant land and the city’s outskirts.
Main allergens and season
- Late winter and early spring (February–March): hazel and alder, especially in damp valleys and near the Vistula.
- Spring (April–May): birch, ash, and oak; pollen comes from both surrounding woods and urban plantings.
- Late spring and summer (May–July): grasses on meadows, the Vistula escarpment, and outer districts.
- Late summer (August–September): mugwort and ragweed on vacant lots, along railways, and around construction sites.
Warsaw’s forecast uses the European CAMS model through Open-Meteo. CAMS values are modeled, not measured at a city aerobiological station; use them as an orientative aid when planning your day.
