[[File:Sahara Dust over Puerto Rico.jpg|thumb|June 2022 haze event caused by [[Saharan dust]].]]
As with other parts of Puerto Rico and the Caribbean, San Juan is often blanketed by waves of [[Saharan dust]] coming from the [[Sahara]] across the Atlantic Ocean in [[North Africa|Northern Africa]]. Although beneficial to the tropical environment,<ref>{{Cite web |last=prsciencetrust.org |date=2020-06-26 |title=Polvo del Sahara: Entre los efectos nocivos de salud y los beneficios al medio ambiente |url=https://prsciencetrust.org/polvo-del-sahara/ |access-date=2022-12-24 |website=Fideicomiso de Ciencias, Tecnología e Investigación de Puerto Rico |language=es-PR}}</ref> these dust storms have recently become hazardous to human health causing haze and overheating in urban areas of the island. Due to San Juan's relatively flat geography, the dust often settles in these flat coastal regions of Puerto Rico as its flow is blocked by the higher altitude [[Cordillera Central (Puerto Rico)|Cordillera Central]] to the south, causing intense episodes of haze to settle for long periods of time, especially during periods of more scarce rainfall.<ref>{{Cite web |date=2022-10-12 |title=Una densa nube de polvo del Sahara deteriora la calidad de aire en Puerto Rico |url=https://www.elnuevodia.com/noticias/el-tiempo/notas/una-densa-nube-de-polvo-del-sahara-deteriora-la-calidad-de-aire-en-puerto-rico/ |access-date=2022-12-24 |website=El Nuevo Día |language=es}}</ref> Recent advancements include early warning systems to prepare the population for these intense episodes by both local authorities and the [[United States Environmental Protection Agency|EPA]].<ref>{{Cite web |date=2022-11-13 |title=Amplían la educación sobre el Sistema de Alerta Temprana para el Polvo del Sahara |url=https://www.elnuevodia.com/ciencia-ambiente/otros/notas/amplian-la-educacion-sobre-el-sistema-de-alerta-temprana-para-el-polvo-del-sahara/ |access-date=2022-12-24 |website=El Nuevo Día |language=es}}</ref>
