Pollen Count & Forecast for Ho Chi Minh City
About Pollen in Ho Chi Minh City
Ho Chi Minh City’s year-round allergy season (January-December) is dominated by Acacia and Casuarina; Acacia (Acacia auriculiformis) common in Tao Dan Park and along boulevards; Casuarina (Casuarina equisetifolia) widespread in Gia Dinh Park and near the Saigon River. Elephant Grass (Pennisetum purpureum) contributes significantly from undeveloped city plots. The dry season (November-April) sees high Bermuda Grass (Cynodon dactylon) pollen levels, originating from suburban fields and the Nhieu Loc-Thi Nghe Canal.
High humidity and traffic emissions trap allergens in narrow urban alleys, leading to localised high concentrations. The monsoon season (May-October) sees high Mould (Aspergillus, Penicillium) spore counts, from damp buildings and decaying organic matter in Le Van Tam Park. Dense construction and dust particles exacerbate respiratory symptoms across city areas.
