Pollen Count & Forecast for Dakar

Dakar’s dry season (November-May) is dominated by Acacia and Grass pollen; Acacia (Acacia) is common across the Mamelles Hills; Grass (Poaceae) is widespread near the Technopole wetlands. Oil Palm (Elaeis guineensis) contributes pollen near Forêt de Hann and the University Cheikh Anta Diop. The rainy season (July-October) sees higher Mango (Mangifera indica) and Baobab (Adansonia digitata) counts near the Almadies district.

Constant sea breezes and Harmattan winds transport particles across the Cap-Vert Peninsula; coastal humidity traps allergens in low-lying areas like Pikine. The humid wet season has elevated Mould (Aspergillus, Penicillium) spore counts; these are from decaying organic matter in the Niayes wetlands and damp city environments.
