Different climates can be distinguished: the coast north of the 45th parallel is much milder because of the warm currents from Brazil, and the entire northern half of the region is significantly warmer in the summer, when sunny weather predominates. Daily temperatures in the summer reach 31 °C in the Rio Colorado region, a general 26 °C to 29 °C in the northern coast, and 24 °C to 28 °C in the northern plain, with nights around 12 °C to 15 °C in the coast and between 7 °C and 10 °C in the steppe.
