The climate in Argentina

Average daytime and nighttime temperatures


All climate diagrams on this page come from the collected data of 117 weather stations.
Weather stations at an altitude above 1180m have not been included.
All data correspond to the average monthly values of the last 20 years.


Back to overview: Argentina

This country would not be the best destination for a beach holiday. The summer high of 13 degrees in the water gives little cause for joy. The warmest and at the same time rainiest province is Norte Grande. The coldest is Tierra del Fuego. Due to the warmer temperatures, the best time for traveling is in January. Less attractive are the cold months from May to August.

Temperature records of the last 73 years

The hottest temperature measured from 1949 to August 2022 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 102 weather stations in Argentina below 1,180 meters altitude, was recorded in 1971 with an average temperature of 13.1 °C. This average temperature will normally be measured every four to six hours, thus also including the nights. Normally, this value is 11.4 degrees Celsius.

The coldest day in these 73 years was reported by the Perito Moreno Airport weather station. Here the temperature dropped to -25.7 °C in July 2000. Perito Moreno Airport 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.

The most precipitation fell in June 2007. With 333.3 mm per day, the Pigue Airport weather station recorded the highest monthly average of the last 73 years. Incidentally, the region with the most rainfall for the whole year is around Iguazu Airport. The driest region is near San Juan Airport.




Long-term development of temperatures from 1993 - 2021

In contrast to single record values, long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. An average value would give a distorted result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and distorts the average again. The subsequent long-term development was therefore reduced to only 24 measuring points in order to have comparable data over as long a period as possible.

In the years 1993 to 2021, 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 January 2012 at 24.8 °C. July 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 17.0 °C in the last years before 2021. So it has hardly changed at all in the past 29 years. This trend only applies to the selected 24 weather stations in Argentina. A considerably more comprehensive evaluation of global warming has been provided separately.

Data basis and methodology

The data from the individual measuring stations are based on the archives of the German Weather Service, individual values averaged and supplemented by own elements. In order to determine a representative national average, average values were first calculated for each part of the country, which were then summarized at the national level. Thus, if a disproportionate number of weather stations are located in a small area, their number does not affect the national average. There are 103 stations in Argentina itself. In 14 cases, neighboring but nearby weather stations were also used to obtain more accurate values.
