Weather: Remember that when it's summer in the United States, it's winter in Argentina, and vice versa. Winters (July-September) are chilly. Summer's muggy heat (December-March) can be taxing at midday but makes for warm nights. During these months Argentines crowd resorts along the Atlantic and in Uruguay.
Spring (September-December) and autumn (April-June), with their mild temperatures are ideal for urban trekking. It's usually warm enough for just a light jacket, and it's right before or after the peak seasons. The best time for trips to Iguazú Falls is August- October, when temperatures are lower and the falls are fuller.
