Portugal is a small coastal nation in southwestern Europe.
Its mainland is located on the Iberian Peninsula, located
38°43° north of the equator and 8°5° west
of the Prime Meridian. Portugal borders only one nationSpain,
to the west and northwith a total of 1,214km of borders.
It is bordered on the east with a 1,793km coastline along
the North Atlantic Ocean. Portugal also controls the Atlantic
islands of Azores and Madeira Islands, which are strategic
locations along western sea approaches to the Strait of Gibraltar
between the Atlantic and Mediterranean Sea. In total, the
country has an area of 92,391 km² of which 91,951 km²
is land and 440 km² water.

Maritime claims:
continental shelf: 200 m depth or to the depth of exploitation
exclusive economic zone: 200 nautical miles (370 km)
territorial sea: 12 nautical miles (22 km).
The continent
Continental Portugal is split in two by its main river, the
Tagus (Tejo). To the north the landscape is mountainous in
the interior areas with plateaus, cut by four breakings lines
that allow the development of relevant agricultural areas.
The south down as far as the Algarve features mostly rolling
plains with a climate somewhat warmer and drier than the cooler
and rainier north. Other major rivers include the Douro, the
Minho and the Guadiana, similar to the Tagus in that all originate
in Spain. Another important river, the Mondego, originates
in the Serra da Estrela (the highest mountains in mainland
Portugal - 1,991 m).
The Islands
The islands of the Azores and Madeira are located in the Mid-Atlantic
Ridge, some of the islands had recent volcanic activity. Originally
two islands, São Miguel Island was joined by a volcanic
eruption in 1563. The last vulcano to erupt was the Vulcão
dos Capelinhos (Capelinhos Volcano) in 1957, in western part
of Faial Island, increasing the size of that island. Dom João
de Castro Bank is a large submarine volcano that lies midway
between the islands of Terceira and São Miguel and
rises 14 m bellow the sea surface. It last erupted in 1720
and formed an island of 1.5 km in length and 250 metres in
altitude, it remained above the water for several years. Scientists
predict a new island can be formed in a not so distant future.
Portugal's highest point is Mount Pico, an ancient volcano,
with 2,351 metres.
The Coast
The Portuguese coast is extensive, it has 943 km in continental
Portugal, 667 km in the Azores, 250 km in Madeira and in the
Savage Islands. The Portuguese coast developed fine beaches,
the Algarve ones are worldwide famous. In Porto Santo Island,
a dune formation is appealing to many tourists. An important
feature in its coast is the Ria de Aveiro (near Aveiro), a
delta with 45 km in length and a maximum of 11 km width, rich
in fish and sea birds. There are four main channels, between
them several islands and islets, and it is where Vouga, Antuã,
Boco, and Fontão rivers meet the ocean. Since the 16th
century, the formation of a sort of narrow headlands formed
a lagoon, seen has one of the most remarkable hydrographic
features of the Portuguese coast. Due to this characteristics,
the region is an ancient producer of salt, and during the
Roman Empire it exported its salt to Rome, seen as a precious
product.
Lakes
There are also several lakes in Portugal, in Serra da Estrela
the Lake Comprida (Lagoa Comprida) and the Lake Escura (Lagoa
Escura) were formed from ancient glaciers. Some lagoons have
the ocean or a river has origin; for instance, the Albufeira
and Óbidos lagoons. While others are originated between
dunes like the lagoons of Braças and Vela.

and rainy in north, warmer and drier in south.
In mainland Portugal, average temperatures are 13ºC
in the North and 18ºC in the South. Madeira and Azores,
due to their location in the Atlantic, are rainy and wet,
and have a narrower range of temperatures.
Portugal is one of the warmest European countries. Spring
and Summer months are usually sunny and the temperatures very
high during July and August, with highs in the centre of the
country between 30°C and 35°C, reaching sometimes
highs of 45°C in the southern interior. Autumn and Winter
are typically rainy and windy, yet sunny days are not rare
either, the temperatures rarely fall below 5°C, usually
staying at an average of 10°C. Snow is common in the mountainous
areas of the north. Portugal's climate is classified as Atlantic-Mediterranean.
As of 2005, the country is facing serious problems due to
lack of rain in the winter. A winter with very blue skies
with some days of unusual low temperatures and other days
with unusual high temperatures.
