Pollen Count & Forecast for Cairns
About Pollen in Cairns
Cairns’ dry allergy season (May-October) is dominated by She-oak and Paperbark pollen; She-oak (Casuarina) prolific along Trinity Inlet; Paperbark (Melaleuca) widespread near Centenary Lakes. Mango (Mangifera indica) contributes significantly from suburban gardens during flowering (August-October). The transition to the wet season (October-December) has high Grass (Poaceae) pollen levels, originating from the Barron River floodplains and along the Esplanade.
Coastal breezes push pollen against the slopes of Mount Whitfield and the Great Dividing Range, causing localised high concentrations. The monsoon season (December-April) has elevated Mould (Aspergillus, Penicillium) spore counts, from decomposing mangrove leaf litter near Smithfield and damp rainforest valley floors.
