Climate - El Centro (California)

In El Centro, and in the nearby city of Imperial, the climate is sub-tropical desert, very mild in winter and scorchingly hot in summer.
The city is located in southeastern California, on the border with Mexico. We are in the Imperial Valley, which is one of the hottest areas of North America, and is also a depression, since the altitude drops below sea level. El Centro is located at 12 meters (40 feet) below sea level, but further to the north, on the shores of Lake Salton, it reaches 65 meters (215 ft) below sea level.
In winter, it is usually sunny, and the temperature reaches or exceeds 20 °C (68 °F) during the day, while nights are quite cold. Sometimes there can be periods colder than usual, in which the temperature drops to a few degrees below freezing at night, although it exceeds 10 °C (50 °F) during the day it.
