Pollen Count & Forecast for Busan

Busan’s spring allergy season (March-May) is dominated by Oak and Pine pollen; Oak (Quercus) prolific on the slopes of Geumjeongsan Mountain; Pine (Pinus) widespread along Haeundae Beach and coastal parks. Japanese Cedar (Cryptomeria japonica) contributes to early spring counts from southern forests. Summer and autumn (June-October) see high Grass (Poaceae), Mugwort (Artemisia), and Japanese Hop (Humulus japonicus) levels, originating from the Nakdong River banks and Samnak Ecological Park.

Coastal winds and mountain topography influence pollen dispersal across the urban corridor. Summer and autumn see elevated Mould (Alternaria, Cladosporium) spore counts, from monsoon humidity and damp environments near the Suyeong River and dense residential blocks.
