This large island in the Mediterranean Sea lies next to Italy. It has a total area of 24,100 square kilometres. To the west of Sardinia is the Sea of Sardinia, which is actually part of the Mediterranean Sea. Over to the east is the Tyrrhenian Sea, which is also an element of the Mediterranean.
The coast of Sardinia 1,849 kilometres (1,149 miles) long and generally high with long, relatively straight stretches of rocky coastline. It has some very deep bays and inlets. There are various smaller islands off the coast.
The island has an ancient geoformation and, is not earthquake-prone like its Nabors’s Sicily and Italy. Its rocks date back beyond the Palaeozoic Era being up to 500 million years old.
Sardinia has few major rivers, the largest being the Tirso at 151 kilometres long. This flows into the Sea of Sardinia, the Coghinas (115 km) and the Flumendosa (127 km). 54 artificial lakes and dams supply water and electricity to the country. Significantly, the best-known lakes are; Lake Omodeo and Lake Coghinas.
The climate on the island of Sardinia is variable, and this is due to several factors including the extension in latitude and the elevation. It’s reasonable to consider the island as having two different macroclimates, one being typically Mediterranean and the other a variant, called the Sub-Mediterranean.
There is a significant concentration of rainfall over the winter and autumn, with some heavy showers in the spring. Snow falls on the hills in the highlands in winter. The average temperature is between 11 to 17 °C, with generally mild winters and hot summers on the coast. Temperatures range from 9 to 11 °C during January and 23 to 26 °C in July. In the sub-Mediterranean part of the island, winters are cold with temperatures dropping to as low as −2 °C and summers can be chilly, occasionally dropping to 16 °C in the shade.
Italy has a typical Mediterranean rainfall distribution with virtually no rain in the summer. Associated with any rain that does fall in the summer is generally a thunderstorm, and sometimes flash floods. The Mistral wind from the northwest is dominant throughout the year, though it is most prevalent in winter and spring.
