Sometimes it happens that the calima is more severe in Lanzarote and Fuerteventura, and other times it happens to be more severe in Tenerife or Gran Canaria.For example in February 2020, which is considered one of the most severe episodes of Saharan dust reaching the Canary Islands, the airport in Gran Canaria had to be closed for several hours because the visibility was so low that no plane could land or take off safely.Calima usually lasts for a few days, usually 2-3 days, sometimes more. This causes the North African high ‐ pressure system to be located at a higher altitude and consequently, dust transport occurs high in the atmosphere within the so-called Saharan Air Layer (SAL).Dust transport is controlled by the African easterly jet and occurs between a height of 3 km and 6 km when the dust layer is lifted above the Trade Wind Inversion layer.In the Canary Islands, the location of the Trade Wind Inversion layer is greatly influenced by seasonal patterns, occurring in summer between 770 m asl and 1380 m asl with an average thickness of about 560 m, while in winter the layer is found at higher altitude (1360 m asl to 1850 m asl) and with a reduced average thickness of about 360 m.Although the calima is more frequent during the winter months, it can also happen during the summer season.The highest mineral dust concentrations are registered during winter and early spring in the Canary Islands and during the late autumn and winter in Cape Verde.According to regional dust models (e.g. Schepanski et al., 2009), the Sahara produces a larger amount of dust during summer, but the dust is transported at higher altitudes of up to 10 km within the Saharan Air Layer.In winter the dust is transported along with the northeast trade winds at far lower altitudes.

And due to their proximity to the Saharan coast, the Canary Islands sometimes suffer from a phenomenon which is known locally as La Calima, when a layer of Saharan dust covers the islands, affecting air quality and visibility.In the Canary Islands, two observation sites have carried out dust measurements:  Izaña (Tenerife) since 1987 and Pico de la Gorra (Gran Canaria) since 1996.The phenomenon known as a calima is what the locals call when a layer of dust from the Sahara comes and covers the islands, making it hard to see or breathe, affecting people with cardiovascular problems or respiratory problems.The Canary Islands are just one of the first areas affected by the layer of Saharan dust, which travels much further, reaching areas of the Caribbean, Central America and South America, especially in the summer months. The Calima is actually caused by a storm or change in weather that affects the Saharan Air Layer.

Like it's 'big brother' the Sirocco the calima blows out of a high-pressure over Northern Africa and the Sahara and is normally drawn northwards ahead of a passing cold-front or depression north of the archipelago.

There are some visitors who are happy with this increase in temperatures, especially if it's happening during the winter months but keep in mind that the air quality drops during that time, so you should not spend that much time outside.
