Far from 28 or 30 degrees Celsius, that the present Caribbean waters, the Chilean cold beaches are located, which fluctuates between 24 ° and 9 ° C during the summer, during its expansion.
These are the coldest in South America.
However, the temperature does not change very much between winter and summer. His media the variation does not exceed 4 ° C between January and July, even in the regions of Arica and Magallanes, according to the site seatemperature.info.
This would take place through a circumpolar current that collides with the island of Chiloé, dividing into two rivers: Humboldt, which continues northwards, and Cape Horn, which turns southward.
Current Humboldt He would be responsible for lowering temperatures, as Oceanography explained by U. Andrés Bello and Geomar, Lucía Villar.
The North is not enough
For Juan Manuel Estrada, director of the Quintay Marine Research Center (Cimarq), it's not enough just to get rid of the north, but the temperatures also depend on geography.
"Open gaps such as Tongoy or Hornitos generate an increase in sea surface temperature. Also in these places, with this geography, the effect residential water much older What does that mean? The water comes in, it stays for a few days and then leaves, "he told the newspaper.
However, not everything is bad: having a great cold does it Rich in nutrients and very productive. "It's not the same thing to eat fish from Chile as one of the Caribbean," Estrada explained.
Although he also argued that the variation in water temperature over the years affected the maturation of invertebrates and molluscs, mentioning, for example, lambs and hedgehogs.
The main beaches
In northern Chile, today 22 ° C were recorded in the famous beach Chinchorro, in Arica. While Cavancha, in Iquique, the sea marked with 21 ° C. With little variation, Antofagasta was presented at 20 ° C.
In the Atacama region, the crystalline waters of Caldera and Bahía Inglesa showed 18 ° C, while southern, the Huasco and Chañaral beaches marked 17 ° C.
The same temperature is repeated in the Coquimbo region, Isla Damas, La Serena and Tongoy, with 17 ° C. Meanwhile, Reñaca, Algarrobo, Maitencillo and Quintay did not exceed 16 ° C in the Buenos Aires region.
Pichidangui, in Oregon's Higgins region rose by 17 ° C but the panorama cools in Maule, with surfing paradises from Iloca, Pelluhue and Curanipe, which does not exceed 15 ° C. Thus it is maintained in the new region, on the beaches Cobquecura and Buchupureo.
In Bío Bío, Estrada's statements are confirmed, as Dichato Bay recorded an increase of 16 ° C in Dichato, remaining further south in Arauco, at the same temperature of 16 ° C Laraquete and Colcura.
Puerto Saavedra, in La Araucanía show 15ºC and more to the south, the temperature in the fog only reaches 14ºC. This temperature is maintained in Chiloé on the crowded beach cucao.
However, if there were variations in the region, it was between Mansa Bay (San Juan de la Costa, in Osorno) with 13 ° C, and Pelluco (Puerto Montt) at 16ºC, protected by the Chacao Canal.
Also, Puerto Cisnes, in the Aysén region, also recorded 16 ° C.
While Magellan the panorama changes sharply: only 9 ° C. As in the island's territory: the famous Anakena beach in Rapa Nui recorded the highest temperature, with 24 ° C.
