Pollen and allergies — Gdynia
Gdynia stretches along the shore of Gdańsk Bay, in a narrow strip between the sea and the moraine hills of Kashubia. Behind the port quays rise the steep kępa cliffs of Redłowo and Orłowo, and further inland begins the Tricity Landscape Park with its pines, beeches, and birches. Compared with neighbouring Gdańsk, whose forecast we describe separately, Gdynia sits more tightly embedded in the rolling landscape, and its districts run along the coast and the railway line.
The windy maritime climate works in both directions. Strong winds off the bay thin the pollen out over the open water, yet those same winds can carry a wave of pollen from deep inland over the city. A cool spring by the water can also delay the start of the tree season compared with central Poland.
Main allergens and season
- February–March: hazel and alder in parks and along streams; right by the sea the start may come late.
- April–May: birch and oak in the Tricity Landscape Park and on the escarpments of the districts.
- May–July: grasses on meadows, lawns, and the green belts along the shore.
- August–September: mugwort and ragweed by roads, rail tracks, and wasteland on the city's rolling hinterland.
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. The model's grid has a resolution of about 11 km, so it does not capture differences between districts at different elevations. It covers six species: alder, birch, grasses, mugwort, olive, and ragweed – olive is included for comparison with southern Europe, since it pollinates only marginally in Poland.
