|Although the most populated areas are generally temperate, Argentina has an exceptional climate diversity, ranging from subtropical in the north to subpolar in the far south. The average annual precipitation ranges from 150 millimetres (6 in) in the driest parts of Patagonia to over 2,000 millimetres (79 in) in the westernmost parts of Patagonia and the northeastern parts of the country. Mean annual temperatures range from 5 °C (41.0 °F) in the far south to 25 °C (77.0 °F) in the north.
Major wind currents include the cool Pampero Winds blowing on the flat plains of Patagonia and the Pampas; following the cold front, warm currents blow from the north in middle and late winter, creating mild conditions. The Sudestada usually moderates cold temperatures but brings very heavy rains, rough seas and coastal flooding. It is most common in late autumn and winter along the central coast and in the Río de la Plata estuary. The Zonda, a hot dry wind, affects Cuyo and the central Pampas. Squeezed of all moisture during the 6,000 m (19,685 ft) descent from the Andes, Zonda winds can blow for hours with gusts up to 120 km/h (75 mph), fueling wildfires and causing damage; between June and November, when the Zonda blows, snowstorms and blizzard (viento blanco) conditions usually affect higher elevations.
