Chile - weather in April

In Chile, April is an autumn month.

North

In the northern part of the coast, where we find the Atacama desert (see Arica, Iquique, Antofagasta), the temperatures are very mild or pleasantly warm, with a daily average ranging from 17.5 to 20.5 °C (63.5 to 69 °F), the sky is usually clear (although mists and low clouds may form in the morning) and it never rains. The ocean in the northernmost part is a bit cool but overall it is acceptable 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 highest altitudes, above 3,000 metres (9,800 feet), 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 16 °C (61 °F), and the sea is cold. In Santiago, in the inland areas of the center, the daily average is similar, but the temperature range is high, so it can get cold at night, while it can get hot during the day. The rains are still very rare, while south of Santiago they gradually increase, and are frequent and abundant already in Concepción.

South

In the south, the temperature is cool, and already quite cold in the extreme south: the daily average ranges from 12 °C (53.5 °F) in Valdivia to 7 °C (44.5 °F) in Punta Arenas. The rains are generally frequent and abundant, 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.
