Mexicali is a busy capital city in Mexico. It sits in the state of Baja California. The city is right on the border with the United States. It sits next to the American city of Calexico. Together, these two cities form a huge metropolitan area. This area is home to about one million people. Mexicali is a very important center for culture and business. It serves as a hub for the whole border region. 
Life in Mexicali is shaped by the desert. The climate is hot and very dry. It is known as a hot arid climate. Summers are extremely long and can be very hot. In July, the average high temperature is 41 degrees Celsius. One day in 1995, the temperature reached 50 degrees Celsius. 
Long ago, the land was very different. The area was a desert delta that was hard to live in. Spanish explorers once crossed the nearby Sonoran Desert. Later, a geologist found that the river left thick soil behind. This soil made the land perfect for farming. In 1900, a company began digging a canal. They linked the dry basin to the Colorado River. This brought water to the thirsty land. 
Farming changed everything for the region. The Mexicali Valley is a very fertile place. It is one of the largest irrigation districts in Mexico. Farmers grow over fifty different kinds of crops there. They grow wheat, cotton, and many vegetables. You can find broccoli, carrots, and lettuce grown here. They also grow asparagus and green onions. 
Today, the city is famous for its big factories. These are called maquiladoras. They are assembly plants that often work with U.S. companies. They make things like car parts and electronics. They also make items for health and space travel. Many people move to the city to work in these plants. This helps the population grow every year. The city is now a major place for making and exporting goods to the world. 
Mexicali is the capital city of the Mexican state of Baja California. It sits directly on the border between Mexico and the United States. The city abuts the American city of Calexico, California. Together, these two cities form a large metropolitan area. This combined area is home to approximately 1,000,000 people. Mexicali serves as a vital economic and cultural hub for the border region known as The Californias. 
The geography of the region is defined by a hot, arid climate. This is known as a BWh climate under the Köppen classification system. This means the area experiences desert weather throughout the entire year. Summers are extremely long and very hot. In July, the mean temperature is 32 degrees Celsius, with an average high of 41 degrees Celsius. On July 28, 1995, the area recorded a temperature of 50 degrees Celsius. 
The history of the area involves many different groups of people. Long ago, Spanish explorers crossed the Sonoran Desert via the "Camino del Diablo," or Devil's Road. This led to the arrival of Catholic missionaries. The indigenous Cocopah people have lived in the region for a long time. Today, they still inhabit a small, government-protected area near the Colorado River delta. In the mid-19th century, a geologist discovered that thick river sediment deposits made the area perfect for farming. These sediments accumulated in a shallow basin below the Sierra de Cucapá. 
Large-scale development began around the turn of the 20th century. In 1900, the California Development Company received permission to cut a canal through the Arroyo Alamo. This canal linked the dry basin to the Colorado River. To attract farmers, developers named the area the "Imperial Valley." By 1904, 405 square kilometers of the valley were irrigated. Around this time, thousands of Chinese laborers were brought in to build the irrigation system. This created a strong Chinese cultural influence in the area. The name "Mexicali" is a portmanteau of "Mexico" and "California."
Agriculture was the primary driver of the local economy for many years. The Mexicali Valley is one of the largest irrigation districts in Mexico. It is a highly fertile region where farmers grow over fifty different types of crops. 
In more recent decades, the economy has shifted toward manufacturing. This is driven by the presence of maquiladoras. A maquiladora is a duty-free assembly plant. In these factories, parts are imported from the United States, assembled, and then returned to the U.S. as finished products. 
Despite its success, the city faces several environmental challenges. Mexicali has been listed as having some of the most polluted air among large Mexican cities. This is partly due to a lack of wind and a lack of pavement, which creates dust. The city also struggles with large amounts of waste, including electronic waste and used tires.
