Chile - weather in October

In Chile, October is a spring month.

North

In the northern part of the coast, where we find the Atacama desert (see Arica, Iquique, Antofagasta), the temperatures are very mild, with a daily average ranging from 16 to 18 °C (61 to 64.5 °F), and although it never rains, mists and low clouds can form, especially in the morning. Even in the northernmost part, the ocean is very cool for swimming.
In the inland areas of the north, occupied by a plateau and the Andes (see Calama, San Pedro de Atacama), it's always sunny. The diurnal temperature range is very wide, it gets cold at night, and at the temperature can drop below freezing.

Center

In the central part of the coast (see Valparaiso, Viña del Mar), the average daily temperature is around 14 °C (57 °F). In Santiago, in the inland areas of the center, the daily average is 15.5 °C (60 °F), moreover, the temperature range is high, so it can get cold at night, while it can get hot during the day. The rains are rare, while south of Santiago they gradually increase.

South

In the south, the temperature is progressively cooler: the daily average ranges from 11.5 °C (52.5 °F) in Valdivia to 7 °C (44.5 °F) in Punta Arenas. Sometimes, cold air from the south can produce rapid decreases in temperature, which can drop below freezing, especially in the first half of the month. The rains are generally frequent and abundant (though less than in autumn), except in the more sheltered areas, located to the east of the mountains (see Balmaceda, Punta Arenas), where they are moderate.
In the southern part of the Andes, it often snows at relatively low altitudes.
