Pollen Count & Forecast for Perth
About Pollen in Perth
Perth’s spring allergy season (September-November) is dominated by Ryegrass and Wattle pollen; Ryegrass (Lolium) prolific in Swan River suburbs and paddocks; Wattle (Acacia) widespread in Kings Park and Bold Park. Paperbark (Melaleuca) contributes significantly along Canning River riverbanks. Summer (December-February) sees high Wild Oats (Avena fatua) pollen levels, originating from the Darling Scarp and along coastal dunes.
The Fremantle Doctor breeze carries pollen inland; the Darling Scarp traps these particles against the eastern foothills. Autumn and winter see elevated Mould (Alternaria, Cladosporium) spore counts, from decomposing leaf litter in Whiteman Park and damp areas around Lake Monger.
