  La Rioja.



La Rioja has a semi-arid climate (BSh, according to the Köppen climate classification), with average temperatures of 5 °C (41 °F) to 19 °C (66 °F) winter and 21 °C (70 °F) to 35 °C (95 °F) in summer, but with maximum temperatures of more than 45 °C (113 °F).

The average annual rainfall is 411.4 mm (16 in), falling almost exclusively during the summer when moist tropical air from the northeast enters the region. La Rioja was always the principal settlement of the province.
The only time it was surpassed in population was in the mid-19th century when Chilecito, a small settlement near the Chilean border based around the Hacienda Santa Rita, became the largest town in the province.


It wasn't until the early 20th century that La Rioja regained the status of being the largest city. The economy of the entire province is historically tied to cattle farming and agriculture, as well as wine production. But the beginning of the 1970s brought to the city an industrialisation thrust that makes La Rioja today an important centre in Argentina's pharmacological industry.

The province is divided in 18 departments (Spanish departamentos).
