Santiago Metropolitan

The Metropolitan Region of Santiago is one of the sixteen regions in which Chile is divided. Its capital is Santiago, which is also the national capital. It limits to the north and the west with the Region of Valparaíso, to the east with Argentina and to the south with the Region of O'Higgins. With an area of ​​15 403.2 km², it is the second smallest of all the regions but it is also the most inhabited, with a population of 7 112 808 inhabitants according to the census of the year 2017. The region is composed of the provinces of Chacabuco, Cordillera, Maipo, Melipilla, Santiago and Talagante.

The Metropolitan region has several special characteristics for being the seat of the capital of the country, within which it was until 2009 to be the only region that was not named through a Roman number. In addition, it is the only region in the entire country that does not have direct access to the Pacific Ocean. The main climatic characteristics of the Metropolitan Region correspond to the "Mediterranean" type, with a long dry season and a rainy winter. The average annual temperature is 22°C, while the warmest month corresponds to the month of January, reaching a temperature of 30°C or higher, and the coldest month corresponds to the month of July with irregular temperatures, generally close to 15°C. The characteristic seal is made up of rains, whose variations make it possible to highlight quite precarious conditions, reaching annual averages of 356.2 mm. Rainfall decreases from the coast to the intermediate depression, to increase again in the Andes mountain range.

In this way, general bioclimatic lines of the region and the central zone of Chile are being established. With regard to rainfall, they present an irregularity, because one year can be very rainy and the next year very dry. In the Colina sector and to a lesser degree in the Santiago area, there are more arid climates with greater thermal fluctuations, which reflect the penetration of the steppe climate, a phenomenon that is due to the presence of the relatively high coastal mountain range that acts as a screen, hindering the penetration of maritime climatic conditions, in terms of relative humidity that occurs in the Santiago basin, it can be said that it decreases progressively.

The presence of the Cordillera de la Costa and the distance from the sea are the main factors that produce the continental climate characteristics of the Santiago Region. In this region there are two types of temperate climates of Mediterranean type: with prolonged dry season and cold of heights in the Cordillera de los Andes. This type of climate develops throughout the regional territory. Its main characteristic is the presence of a prolonged dry season and a well-marked winter with extreme temperatures reaching zero degrees. Santiago registers an average annual temperature of 22°C but the thermal contrasts are strong in summer the maximum reaches values ​​higher than 30°C during the day. Rainfall is recorded during the winter seasons, especially during the months of May, June, July and August. Santiago presents 369.5 mm of annual average falling water.

Within the Santiago Basin there are local climatic differences produced by the effect of the relief, at the eastern foot of the Cordillera de la Costa and, due to the role of its climatic screen, there are areas of greater dryness, and even with semi-arid characteristics. The cold climate of height is located in the Cordillera de los Andes above 3000 meters high. The low temperatures and the solid precipitations characterize this climatic type, which allows the accumulation of snow and permanent ice fields in summits and gorges of the high mountain range.
