About Buenos Aires
Buenos Aires is the capital and largest city of Argentina, and the second-largest metropolitan area in South America, after Greater São Paulo. It is located on the western shore of the estuary of the Río de la Plata, on the continent's southeastern coast. The Greater Buenos Aires conurbation, which also includes several Buenos Aires Province districts, constitutes the third-largest conurbation in Latin America, with a population of around fifteen and a half million.
The city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include the towns of Belgrano and Flores; both are now neighborhoods of the city. The 1994 constitutional amendment granted the city autonomy, hence its formal name: Ciudad Autónoma de Buenos Aires (Autonomous City of Buenos Aires). Its citizens first elected a Chief of Government (i.e. Mayor) in 1996; before, the Mayor was directly appointed by the President of the Republic.
The official language of Argentina is Spanish. Most hotel staffs can speak English.
Climate and Expected Weather
Buenos Aires has a humid subtropical climate, with very humid summers and mild winters. The warmest month is January, with a daily average of 25.1 °C (77.2 °F). Most days see temperatures in the 28 to 31 °C (82 to 88 °F) with nights between 16 to 21 °C (61 to 70 °F). Heat waves from Brazil can push temperatures above 35 °C (95 °F), yet the city is subject to cold fronts that bring short periods of pleasant weather and crisp nights. Relative humidity is 64–70% in the summer, so the heat index is higher than the true air temperature. The highest temperature ever recorded was 43.3 °C (110 °F) on 29 January 1957. Spring (September to November) and autumn (March to May) are generally mild and volatile, with averages temperatures of around 17 °C (63 °F) and frequent thunderstorms, especially during the spring.
Currency & Banking
The “peso” is the currency of Argentina, identified by the symbol $ preceding the amount in the same way as many countries using dollar currencies. It is subdivided into 100 centavos. Its ISO 4217 code is ARS. Several earlier currencies of Argentina were also called "peso"; as inflation progressed a new currency with a few zeroes dropped and a different qualifier (peso national currency, peso law 18188, peso argentino) was introduced. Since 1970, thirteen zeroes have been dropped (a factor of ten trillion). Nowadays the equivalency with US dollar goes from 1 dollar = 9 pesos (official exchange rate) to 1 dollar = 13 pesos (unofficial rate).
