Considerations for Travelers in Argentina During March
Traveling to Argentina in March is an excellent choice for those who prefer mild temperatures and fewer crowds. However, there are some important considerations to keep in mind to ensure a smooth and enjoyable experience.
Packing Essentials for March
Since March can bring a variety of weather conditions across Argentina, it’s important to pack accordingly. For Buenos Aires and Mendoza, lightweight clothing is ideal for daytime activities, with a light jacket or sweater for the evenings.

Make sure to check the weather forecast and local conditions before traveling to remote areas or mountain regions.
Currency and Economic Considerations
The official currency of Argentina is the Argentine Peso (ARS). While credit cards are accepted in most urban areas like Buenos Aires, it is advisable to carry cash when traveling to more remote locations. ATMs are widely available in cities, but some rural or mountain areas may have limited access to banking facilities.
