Sao Tome and Principe Weather and Climate

Geographical location

According to COUNTRYAAH, the São Tomé and Príncipe archipelago is about 205 kilometers south of Nigeria, west of Gabon and Equatorial Guinea. Only the Seychelles undercut the size of the second smallest state in Africa, whose larger island São Tomé is 48 kilometers long and 32 kilometers wide.

Only around 10 percent of the population live on the much smaller island of Príncipe, although there are only around 200,000 inhabitants in the small island state, whose southern tip extends to the equator. São Tomé and Príncipe are of volcanic origin and therefore very mountainous, the highest point (the Pico de São Tomé) exceeds 2000 meters.

The former crown colony of Portugal has been independent since 1975, but the official language is Portuguese to this day. The most important export good is still the qualitatively outstanding cocoa, whereby enormous oil discoveries off the coast of the islands promise an economic change.

As a result of these potential fortunes, São Tomé and Príncipe suffers from unstable governments that have again stumbled upon corruption scandals. However, the country is considered an extremely safe travel destination. 80 percent of the population are Catholics, the local currency is the Dobra.

The paradisiacal island place, still far away from mass tourism, is mainly accessible via Lisbon and Porto. The international airport is served by TAP and TAAG Angola Airlines (via Luanda), for example, and the flight time from Lisbon is around 9 hours. German citizens do not need a visa for stays of up to 15 days.
