Climate in Argentina



The generally temperate climate ranges from subtropical in the north to subpolar in the far south. The north is characterized by very hot, humid summers with mild drier winters, and is subject to periodic droughts. Central Argentina has a temperate climate, with hot summers with thunderstorms, and cool winters; and higher moisture at the east. The southern regions have warm summers and cold winters with heavy snowfall, especially in mountainous zones.

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 Zonda, a hot dry wind, affects west-central Argentina. 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; when the Zonda blows (June–November), snowstorms and blizzard (viento blanco) conditions usually affect higher elevations. 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
