Pollen Count & Forecast for Santo Domingo

Santo Domingo’s year-round allergy season is active with grass and tree pollen; Guinea Grass (Megathyrsus maximus) frequent in the Mirador Sur Park; Bermuda Grass (Cynodon dactylon) common along the Ozama River banks. Casuarina (Casuarina equisetifolia) pollen is high near the National Botanical Garden. The dry season (January-April) sees high Mango (Mangifera indica) and Pigweed (Amaranthus) counts from open urban outskirts.

High coastal humidity and steady trade winds are factors in allergen dispersal. Coastal moisture and river proximity see elevated Mould (Aspergillus, Cladosporium) spore counts, from damp environments near the Isabela River and Mirador del Norte. Sahara dust events are a source for fungal spores and minerals during the summer.
