A new wave of Saharan dust is sweeping across Greece on Friday, bringing reduced air quality and muddy rain, according to the National Observatory of Athens.
The phenomenon is forecast to initially affect western parts of the country, including the Ionian Islands, the Peloponnese, Epirus, western mainland areas and Crete.
On Saturday, the dust cloud is expected to move further east, reaching Central Greece and Thessaly, while also affecting, to a lesser extent, islands in the northern Aegean.
PM10 particle concentrations are projected to reach between 50 and 100 micrograms per cubic meter in several areas, exceeding local air quality limits.
At the same time, so-called rain dust is forecast. Light rainfall carrying dust particles is expected to intensify from early Friday in western Greece. The weather system is then expected to spread northwards by Friday afternoon, impacting regions including Macedonia and Thrace.
Health risks associated with Sahara dust cloud
The dust from Africa is not just a visual or respiratory nuisance. Rather, it carries significant health risks. Numerous studies by Greek and international researchers have shown that African dust clouds often transport toxic heavy metals such as lead, arsenic, nickel, chromium, vanadium, and zinc.
Authorities advise residents, particularly vulnerable groups, to monitor updates and limit outdoor activity during peak dust concentrations.
