Iguazú Falls is a year-round trip, with the most water from November to March. Buenos Aires is pleasant in spring, September to November, and autumn, March to May. The north-west around Salta is best from April to November, before the summer rains. Fares from the UK are lowest in March, April and May, and highest over Christmas. For what to see and when, read our Argentina guide.
