French Guiana: geography
Defined by DigoPaul, the country of French Guiana is located on the northeast coast of South America and borders on
Brazil to the south, Guyana to the west, French Guiana to the east and the
Atlantic Ocean to the north. The country is a department and region of
France. It is thus represented in the European Union by France.

Area, limits of coastline
French Guiana covers a total area of 86,504 km².
Over 90% of the country is covered by dense rainforest and almost deserted.
Landscapes
The lowland, which is up to 5 m below sea level, made up of alluvial land, is
approx. 70 kilometers wide on the coast and is secured against flooding with the
help of dams.
The adjacent part of the country is a flat hill country that rises up to 150 m
high. The highlands take up around two thirds of the land area.
Gold production
The legal and illegal gold production has meanwhile become the most important
economic factor alongside the Kourou space center. Between 15,000 and 30,000
people should now work here.
Since mercury is used in gold processing, large parts of the rivers and streams
are contaminated with this toxic metal.
Borders
French Guiana shares a border with a total of two states. These are the limits
to:
- Brazil with a length of around 730 km, so Brazil has a 730 km long
border with the EU. An important border river is the 370 km long Rio
Oiapoque, which flows into the Atlantic.
- Suriname with a length of around 510 km.
Coastline
French Guiana has a coastline to the Atlantic with a length of around 380
km. The marshy coastal plain is not very wide (15 to 48 km).
Tidal range
In Cayenne, the mean tidal range of the Atlantic averages around 1.5 m.
For detailed explanations of ebb and flow, see Tides, Ebb and Flow.
Compare
The world's highest tidal range can be found in the Bay of Fundy in
Canada, where it is up to 16 m, with spring tide even over 20 m. The Bay of
Fun-dy is located on the Atlantic between the Canadian provinces of New
Brunswick and Nova Scotia, which is called Nova Scotia in German and whose
capital is Halifax.
On the German North Sea coast it varies between 1 m and 3 m.
In the western Baltic Sea, on the other hand, the tidal range is only 0.3 m,
while it is barely noticeable in the eastern Baltic Sea.
Longitude and latitude
French Guiana covers the following latitude (abbreviation Δφ) and longitude
(abbreviation Δλ):
Δφ = from around 2 ° to 6 ° north latitude
Δλ = from around 52 ° to 55 ° west longitude |
You can find detailed information on this subject under: Geographical
longitude and latitude.
Legal time
For Cayenne, the following value applies to Central European Time (CET). A
minus sign means that it is earlier there and a plus sign that it is later than
after CET:
More detailed explanations of the time can be found under: Time zones, time.
Highest point of the sun in Cayenne
Cayenne lies at a north latitude of around φ = 5 °.
If the sun, or its pixel, is exactly above the city, i.e. at around 05 ° N, the
sun will be exactly vertically above the city at noon. This happens exactly
twice a year, roughly 18 days after March 21st and 18 days before September 21st
(for details see position of the sun).
Attention
If the image point of the sun (declination) is north of the latitude of Cayenne,
i.e. around 5 ° N, the sun is not in the south at noon, as in our latitudes, but
in the north. The sun moves from east to north to west, where, like us, it sets.
mountains
Mont Bellevue de Inini
The highest mountain in the country is Mont Bellevue de Inini. It
reaches a height of 850 m.
Tumuc-Humuc Mountains
Other high mountains are the Tumuc-Humuc Mountains on the Brazilian
border in the south.
Rivers
Fleuve Marouini
The longest river in the country is the Fleuve Marouini with a length of around
725 km.
Other rivers in the country that all flow towards the Atlantic:
- Fleuve Approuague
- Fleuve Sinnamary
- Fleuve Oyapock
- Mana
- Tampoc
- Riviere Camopi
Islands
Iles du Salut Group
French Guiana has several small islands, such as the Iles du Salut
Group with the islands:
Ile du Diable, Ile Royale and Ile Saint-Joseph.
Furthermore, the Pere and Mere island groups,
the Malingre and the Remire islands and the
two Connectables.
The Atlantic
French Guyana borders the Atlantic
Ocean over a length of around 380 km. With an area of around 106 million km²,
the Atlantic Ocean (Atlantic) is the second largest ocean in the world after the
Pacific. It separates America from Europe and Africa. At 9,220 m, it has its
deepest point in the Milwaukee Deep - part of the Puerto Rico Trench. Its salt
content is on average 3.54% (g/l). Its water volume is around 355 million km³.
Coming from the Gulf of Mexico, the Gulf Stream crosses the Atlantic to the
coast of Norway and is largely responsible for the climate in Western and
Northern Europe.
The Atlantic includes numerous so-called marginal seas - e.g. the American
Mediterranean. In addition, the Atlantic - especially in seafaring - is divided
into the North Atlantic and South Atlantic. The Strait of Gibralta is certainly
a very well-known connection between the Atlantic and the Mediterranean, where
it separates Europe (Gibralta/Great Britain) from Africa (Morocco). The Panama
Canal connects the Pacific with the Atlantic for around 82 km. The Atlantic and
Pacific meet at the legendary Cape Horn on the southern tip of the American
continent.
