Spectacular sunrise on the Gavà beach today, at the gates of summer, engulfed by the Saharan dust. Earthy sky, with the color of Mars that leaves us with a very brownish landscape in the sky, as can be seen in the Photos of the Readers of La Vanguardia.

This is how the Baix Llobregat coastline has looked about to enter the summer season, which begins on June 21 and will last 93 days, that is, until September 21. In Spain, summer begins exactly at 4:57 p.m.

Calima is a meteorological phenomenon that occurs in the presence of Saharan octopus in the atmosphere, episodes that are becoming more frequent.

Saharan dust has pros and cons. And especially when the heat arrives. As explained by the State Meteorological Agency (Aemet), suspended particles degrade air quality, and may have negative effects on health, the environment and some economic activities, particularly aviation, due to decreased visibility, and the solar power generation.

What is positive about the haze, apart from enjoying sunrises with a colored sky? According to Aemet, “its content of mineral salts and metals can have a positive fertilizing effect for agriculture and fishing in the areas where these particles are deposited.”
