Argentina in May

Argentina's seasons flip from the northern hemisphere, making October through March ideal for most regions. Buenos Aires shines in spring (September-November) when jacaranda trees bloom purple and temperatures hover around 70°F. Summer (December-February) brings heat and humidity to the capital but perfect weather for Patagonia's hiking trails and glacier viewing. Mendoza's harvest season (February-April) offers wine tours with grape-picking experiences, though temperatures can hit 90°F. Salta's dry climate works year-round, but summer rains (December-March) can flood mountain roads. Winter (June-August) suits northern Argentina exploration — Iguazu Falls flows strongest, and you'll avoid summer crowds. Patagonia operates on a short season — most lodges and tours run October through April only. December and January bring crowds and premium prices, but also 20-hour daylight and warmest weather. Shoulder seasons (October-November, March-April) offer better deals and fewer tourists, though some services may be limited. Pack layers regardless of season — mountain weather changes quickly, and air conditioning isn't universal.
