During a long time of the year it is pleasantly warm with temperatures of continuously above 25 degrees Celsius. Just the water temperatures with a maximum of 13 degrees are less comfortable for bathing.

Temperature records of the last 70 years
The hottest temperature measured from 1949 to June 2019 was reported by the Catamarca weather station. In October 2009 the record temperature of 47.0 °C was reported here. The hottest summer from July to September, based on all 103 weather stations in Argentina below 1220 metres altitude, was recorded in 1971 with an average temperature of 13.1 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 11.4 degrees Celsius.
The coldest day in these 70 years was reported by the weather station Perito Moreno Airp. Here the temperature dropped to -25.7 °C in July 2000. Perito Moreno Airp lies at an altitude of 429 meters above sea level. The coldest winter (January to March) was in 1949 with an average temperature of 19.9 °C. In Argentina, it is usual to have about 1.7 degrees more at 21.6 °C for this three-month period.
Long-term development of temperatures from 1993 - 2019
In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 24 measuring points in order to have actually comparable data over as long a period as possible.
In the years 1993 to 2019 there were only these 24 weather stations in the whole country, which reported continuous temperature values. From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was Januar 2012 with 24.8 °C. Juli 2007 was the coldest month with an average temperature of 7.4 °C.
The average annual temperature was about 16.8 °C in the years after 1993 and about 16.9 °C in the last years before 2019. So it has hardly changed at all in the past 27 years. This trend only applies to the selected 24 weather stations in Argentina. A considerably more comprehensive evaluation of the global warming
has been provided separately.
