In 2022, the Costa del Sol experienced a unique phenomenon: the calima. This Saharan sandstorm left thousands of buildings and vehicles covered in mud. Clean-up services were needed for days and months to repair the damage.

Other cities and autonomous communities, such as Córdoba, Cádiz, Madrid, and Castilla León, were also affected by the calima in 2022. The Canary Islands, being closest to the Sahara, suffer these episodes more often, usually monthly.

Will we go through another calima like this one? That’s the big question we all have.

We cannot be sure if a similar event will occur again in the short term due to the lack of meteorological predictions or certainty. However, it is clear that climate change is causing more frequent and intense weather phenomena, such as floods, fires, thaws, and storms, than in years past.

Therefore, we can venture to say that yes, it will happen again, although we cannot give a specific date.

What can we do to prevent the effects of haze?

Although we don’t know if it will happen again, there are ways to prevent haze from having such disastrous effects on our homes: the application of water repellents. Water repellents are products that, when applied to a surface, can repel dirt. For example, limescale, mud, and sand won’t be able to adhere and penetrate the surface. With the application of pressurized water, it can be removed very easily.
