Pollen Count & Forecast for Istanbul
About Pollen in Istanbul
Istanbul’s spring allergy season (March-May) is dominated by Pine and Plane pollen; Turkish Pine (Pinus brutia) prolific in the Belgrad Forest and Prince Islands; Oriental Plane (Platanus orientalis) widespread along Bosphorus shores and Gulhane Park. Cypress (Cupressus) and Oak (Quercus) contribute significantly from Emirgan Park. Summer (May-August) sees high Grass (Poaceae) and Pellitory (Parietaria) levels, originating from Camlica Hill and the Marmara Sea coast.
Black Sea and Bosphorus winds channel pollen across the city; high humidity increases allergen potency. Autumn and winter see high Mould (Alternaria, Cladosporium) spore counts, from damp conditions in the Fatih district and leaf litter in Yildiz Park.
