In Las Fotos de los Lectores de La Vanguardia we can appreciate the sunrise this Sunday on Gavà beach, in Baix Llobregat, engulfed by Saharan dust.

The haze is very powerful these days in Catalonia and in this case it makes itself felt along the coast of the Barcelona area in the early stages of the day.

The haze is a meteorological phenomenon that occurs in the presence of Saharan dust in the atmosphere. It can be seen in this image of the hazy sky with a calm sea in Gavà.

The disappearance of the haze is conditioned by changes in atmospheric pressure, which can give rise to wind or rain.

The immediate effect produced by the haze, always depending on its density, produces a decrease in visibility as well as slight discomfort in the eyes, nose and throat.

In addition, it is advisable not to expose yourself and protect yourself from the haze if you have respiratory problems such as asthma or even allergies.
