August is a real tropical month in Cape Verde. There is some rain and the temperatures are high. This means that you can enjoy great weather in August on the Cape Verde islands. Cape Verde consists of nine inhabited islands, namely Sal, Boa Vista, São Nicolau, São Vicente, Santo Antão, Santiago, Maio, Fogo and Brava. The ever-present and cooling trade winds on the archipelago ensure that it can be pleasant in Cape Verde despite the high temperature.

Data accounting

Every figure on this page comes from the climate table on Cape Verde climate and weather: measuring station Sal, Amílcar Cabral airport (Espargos), reference period the 1991–2020 climate normal. A day of rain is a day with at least 1 millimetre of rainfall. Those values hold for Sal and for the flat eastern islands. The other islands have no measuring series of their own, so we give no figures island by island. On the mountainous islands such as Santo Antão and Fogo it is cooler and wetter at altitude.

The graph above shows something different from the table: how the month runs day by day, taken from the historical daily reports of weather station 85940 over 2012 to 2018. That series is not a climate normal and is not the source of any figure in the text; it is there to show whether a month runs flat or erratic.
