Pollen Count & Forecast for Bogotá

Bogotá’s primary allergy seasons (December-March and July-August) are dominated by Oak and Cypress pollen; Andean Oak (Quercus humboldtii) is common in the Cerros Orientales; Mexican Cypress (Cupressus lusitanica) is widespread across residential sectors and El Virrey Park. Eucalyptus (Eucalyptus globulus) contributes significantly from the eastern hills. High year-round levels of Kikuyu Grass (Pennisetum clandestinum) are present, originating from Simón Bolívar Park and the Bogotá River wetlands.

High altitude and frequent thermal inversions trap pollen within the Sabana de Bogotá. Rainy months see elevated Mould (Aspergillus, Penicillium) spore counts, from damp organic matter in urban parks and surrounding wet paramo ecosystems.
