Climate
The Argentine mainland is mostly temperate, with seasons reversed from those in the northern hemisphere. The northern areas of Salta and around Iguazu are tropical, while southern Patagonia has a harsh winter climate and has great daily variability, even in summer. There is always a season for tourists somewhere in the country, and bear in mind that temperature varies with altitude as well as latitude.

Festivals & Holidays
There are few traditional fiestas in Argentina although there are plenty of public holidays. In January and February the colourful Gualeguaychu Carnival takes place at Entre Rios, 200km from Buenos Aires. In November, San Antonio celebrates the culture of the gaucho with the Fiesta de la Tradición.
Currency
The local currency is the Argentine peso. Current exchange rates are available via Google currency conversion or the OANDA currency converter. It’s not advisable to try to acquire Latin American currency before travelling, if a currency is available in high street banks or exchange outlets the exchange rate is usually very poor. You can change US dollar cash or travellers checks locally and obtain cash advances via ATMs in most towns and cities. We’d advise that you tell your bank you intend to use your card abroad before you set off.
Visas
British citizens can find up-to-date information on the Foreign & Commonwealth Office website. Citizens of other countries should consult their embassy or the Embassy of the Argentine Republic in London before travel.
Vaccinations
We recommend that you always check with your own travel clinic or health professional before you travel, for advice specific to your requirements. The NHS Fit For Travel website contains for up-to-date health advice and lists the common vaccinations for travellers to Argentina.
