Chamical is a small city in, and the seat of government of, Chamical Department in the south of La Rioja Province of Argentina. [1] With a population of 12,919 permanent residents at the 2010 census [INDEC], up from 11,831 at the time of the 2001 census, it is the third-most populous settlement in La Rioja Province after Chilecito. It is home to the CELPA aerospace test center, founded in 1961 and operated by the Argentine Air Force. The town, which is crossed by the Tirante wadi, lies on the Ruta 38 (Spanish Wikipedia), around 140 km from La Rioja (2 hours by bus), and some 300 km from Córdoba (4 hours by bus).

Contents

This young urban habitation has been an important site in several stages of Argentine history during the past fifty years. Chamical has plentiful wilderness touristic spots, such as "Las Ollitas" (a natural waterfall lake) and "La Salina" (a long salt flat).

Chamical is regarded as the tango hub in La Rioja Province.

Name origin

Chamical got its name from the many specimens of the medicinal herb known in Spanish as chamico (meaning "jimsonweed" in said language) found growing wild in the area.

Geography

Chamical is located in the droughty Llanos Riojanos (Spanish for "Riojan Plains") and has four marked seasons, giving it a BSh hot semi-arid climate under the Köppen climate classification. The dry period of April to October is mild to cool, with the normal monthly mean temperature reaching its lowest in July at 11.7 °C (53.1 °F). The rainy period of November to March is warm to hot, with the normal monthly mean temperature peaking in January at 26.4 °C (79.5 °F). There has hardly ever been any snow or frost, but there has often been hail.

Total yearly precipitation averages a scanty 448.8 millimetres (18 in) with plentiful sunny days, and the rainfall centers in summer. The wettest month is January, during which time Chamical receives an average of 94.1 millimetres (4 in).

Winters are quite cool, but usually sunny; rather, snowfall is an odd occurrence. The Servicio Meteorológico Nacional reports that July is the coldest month with a mean high of 18.7 °C (65.7 °F) and a mean low of 5.7 °C (42.3 °F). Springtime is mild, windy and usually warm. Summers are hot (as is common with La Rioja Province), somewhat rainy and, most often, the mercury rises to 38 degrees Celsius (≈100 Fahrenheit) or higher in the shade, which means unpleasant. The rain brings some relief from the stifling Riojan heat. January, the warmest month, has an average high of 33.4 °C (92.1 °F) and an average low of 20.1 °C (68.2 °F). Fall is mild and pleasant, but can go chilly.

The highest temperature ever recorded was 45.5 °C (113.9 °F) on December 25, 2013 while the lowest temperature on record was −7.7 °C (18.1 °F) on July 31, 1993. [2]
