The current north of the Canaries, has a cooling effect on the islands of Cabo Verde, making the air temperature more bearable than it would expect in any case at this latitude. Conversely, the islands do not receive the upwellings (cold streams) that affect the West African coast, so the air temperature is cooler than in Senegal, but the sea is actually warmer, because the orographic relief of some islands, such as Sao Miguel with steep mountains, cover it with rich woods and luxuriant vegetation where the humid air condenses and soak the plants, rocks, soil, logs, and moss.
