Saharan sand will blow across southern and western France next week and reach as far north as Brittany, as dust particles travel thousands of kilometres from North Africa.
Minute sand particles began to arrive at the end of the week (February 27) but will see a spike in activity on Monday and Tuesday (March 2 and 3).
Particles may continue to fall as late as the end of next week (March 6).
They will turn skies hazy, leave sunsets ochre, and deposit themselves on mountains, hills, and roads.
However, they are unlikely to remain stuck onto cars and buildings, as a lack of rain (dry weather is forecast next week) will prevent the sand from coagulating and settling.
That being said, it may still be best to wait to wash your car until the episode is over, as deposits may build up throughout the week.
General health warnings do not accompany the arrival of Saharan sand, but those with breathing conditions such as asthma should avoid strenuous outdoor activities during a peak.
Despite being small enough to be inhaled, the particles are not generally deemed hazardous.
Sand deposits happen throughout year
Saharan deposits are a semi-frequent phenomena in Europe, as windy conditions whip up desert sands several thousand metres into the air and winds bring them over the Pyrénées (or around the mountains).
The deposits eventually fall to lower altitudes and settle.
Since 2024, this phenomenon has become more common, particularly during the winter and spring months (it mostly occurs during summer), without a clear reason why.
Next week sees the first major Saharan deposits of the year, with the last major occurrence in France being in November 2025.
