Average weather, temperature, rainfall, sunshine hours

Perito Moreno has a
temperate arid climate (according to the Köppen classification, cold semi-arid or steppe climate - BSk), with cold winters and cool summers.
The
wind, which blows all year round, often moderate or strong, increases the feeling of cold. In addition, there are temperature changes from one day to the next.
The town is located in southern Argentina, in the province of Santa Cruz, at 400 meters (1,300 feet) above sea level. About 15 km (9 mi) to the west is
Lake Buenos Aires, shared with Chile, which in the Chilean part is called Lago General Carrera. About 165 km (100 mi) to the southeast, at 600 meters (2,000 ft) above sea level and above a canyon, is the Cueva de las Manos, which contains prehistoric paintings.
In this area of Argentina, the Andes are across the border, in Chile. To find mountains with glaciers while remaining in Argentina, you have to go further south or further north.
The name Perito Moreno should not be confused with other geographical places that have the same name. In fact, about 150 km (93 mi) to the south is the
Perito Moreno National Park, occupied by mountains and valleys that descend to 900 meters (2,950 ft) above sea level. Instead, the
Perito Moreno glacier is located much further south, within the Los Glaciares National Park, near El Calafate.
In
winter, from June to August, the average temperature is slightly above freezing. Snowfall, which is usually not abundant since the climate is dry, generally occurs from May to September.
In addition, there can be cold spells, where the temperature can drop to around -15 °C (5 °F), and occasionally below. The record is -25.7 °C (-14.3 °F), set in July 2000. In June 2020, the temperature dropped to -20 °C (-4 °F).
Summer, from December to February, is mild during the day, with often cold nights. The records are around 0 °C (32 °F) even in summer.
However, there can sometimes be short-lived heatwaves, though less than in other areas of Patagonia. The record is 38.2 °C (100.8 °F), set in February 2019.
Best Time
The mildest time in Perito Moreno is the summer, from December to February. It must be said that it can sometimes get very hot, although rarely, only during the day and usually only in January and February. It is worth remembering that at night, it can get cold also in these months.
