Pollen Count & Forecast for Miami

Miami’s year-round allergy season is dominated by tree and grass pollen; Oak (Quercus) is common in Coconut Grove and Matheson Hammock Park. Pine (Pinus) trees release heavy dust near Oleta River State Park. Summer and autumn have high Grass (Poaceae) levels; these originate from residential lawns and the Everglades National Park. Ragweed (Ambrosia) is a primary trigger along the Miami River.

High humidity and Atlantic sea breezes circulate allergens across the flat coastal plain. Frequent rainfall increases Mould (Alternaria, Cladosporium) spore counts; these are common in damp mangroves and urban canals.
