Cape Verde is an archipelago of 10 islands located on the African continent off the coast of Senegal in the Atlantic Ocean.
Its geographical location makes it a relatively pleasant and sunny country all year round. The climate is therefore arid tropical with hot temperatures all year round (between 25°C and 37°C).
The best time to go there is between November and April, this is the dry season.
From May to October, the temperatures are higher with a lot of humidity, especially for the southern islands. This is the rainy season.
As far as I am concerned, I went to Cape Verde during the month of November. It's a great month to travel to Cape Verde with decent temperatures (between 25°C and 35°C) depending on the islands. The weather was relatively nice, I must have had a day or two with rain in Santo Antao on the heights of the island.
