Pollen Count & Forecast for Athens

Athens’ spring allergy season (March-May) is dominated by Olive and Pine pollen; Olive (Olea europaea) groves common near Philopappos Hill and the National Garden; Aleppo Pine (Pinus halepensis) concentrated on Mount Parnitha and Mount Lycabettus. Pellitory (Parietaria) contributes significantly from ancient stone ruins. Summer (May-July) sees high Grass (Poaceae) pollen levels, originating from along Kifissos River banks.

Strong northern Etesian winds carry allergens across the Attica basin; the surrounding mountains trap particles in the urban center. Autumn and winter see elevated Mould (Alternaria, Cladosporium) spore counts, from decomposing leaf litter in parklands and damp city environments.
