Geography
[edit]
Aerial view of Praia.
Geographically, Praia may be described as a set of plateaus and their surrounding valleys. These plateaus generally have the name achada (Achada de Santo António, Achada de São Filipe, Achada Eugénio Lima, Achada Grande, Achadinha, etc. — achada being a Portuguese word to designate a volcanic plateau), but the central one is called Plateau. The urban settlement is made mostly on top of these plateaus and along the valleys. The islet of Santa Maria is in front of the beach bearing the same name.
For a long time, only the Plateau was considered to be the city, the other neighbourhoods being relegated to the condition of peripheral suburbs, in spite of always having a close relationship with the Plateau (people movements, goods and services exchanges, etc.). This is why only the Plateau previously had relatively well-developed urbanization with its own infra-structures. The remaining neighbourhoods developed in a more organic, chaotic way.
Only after independence did the Plateau merge with the other neighbourhoods to constitute what is now considered the City of Praia. The whole city was, at the time, equipped with adequate infrastructure. Urbanization begun immediately after independence and sought to expand north.
Climate[edit]
Praia has a desert climate (Köppen: BWh) with a short wet season and a lengthy, very pronounced dry season. In fact, outside of the months of August, September and October, little precipitation falls on Praia. The city on average sees about 210 millimetres (8.3 in) of rain per year. Since the coldest month is far above 18 °C (64 °F) its temperature patterns resembles a tropical climate, but lacks enough precipitation to be classified as such. Despite the fact that it has an arid climate, Praia seldom gets very hot or very cold, due to its oceanside location on Santiago Island. Temperatures are warm and constant with an average high temperature of 27 °C (81 °F) and an average low temperature of 22 °C (72 °F).
