Calima Causing Poor Air Quality On The Costa Del Sol

A calima is affecting conditions on the Costa Del Sol this week. The Saharan sand cloud is causing a hazy effect as visibility is reduced in some areas, and clouds have a yellow / orange tint. The calima is also creating a build up of sand and dust on roads, cars, and buildings. Fortunately there is no rain forecast at the moment.

Humidity levels are high this week, reaching 70% at times. This combined with the sand in the air makes things feel stuffy and muggy. Asthma and hayfever sufferers may also notice that symptoms are more severe.

What Is A Calima?

The phenomenon known as “calima” is a haze caused by sand which has been blown from the Sahara desert. Skies on the Costa Del Sol can turn orange, and sometimes bright red. The calima can leave a sandy coating on buildings, cars, and footpaths.

Calima can also be a health hazard to people with respiratory problems and allergies. It is known to cause symptoms such as coughing, nasal congestion, eye irritation, and headaches.

The impact of a calima is dramatically increased if it rains. This causes a muddy silt to be deposited which can make driving conditions difficult and create problems for outdoor facilities including swimming pools.
