El Cajon is a city in San Diego County, California. It's about 17 miles (27 km) east of downtown San Diego. The city's name comes from a Spanish word, El Cajón, which means "the box." This name was chosen because the valley around the city looks like a box. That's why people sometimes call El Cajon "the Box."

What's in a Name?

The name El Cajón (meaning "the box" in Spanish) was first used on September 10, 1821. It described how the valley was "boxed-in." The name appeared on maps as "Cajon" in 1873 and 1875. When the modern town grew, its post office was named "El Cajon."
In 1905, a California historian named Zoeth Skinner Eldredge insisted that the name be changed back to "El Cajon."
A Look Back: El Cajon's History
Early Days and Ranchos
During Spanish rule (1769–1821), the government created large land areas called ranchos. These were given to the Roman Catholic Church, which built many missions. In the early 1800s, mission leaders looked for good places for their cattle. They found the El Cajon Valley. The hills around it kept cattle from wandering off. They also helped collect the little rainfall. For many years, the El Cajon Valley was used for the mission's cattle.
Individual people didn't get land until the Mexican era (1821–1846). In 1834, a law was passed to divide church land among Native American people. But most of the land was given to wealthy "Californios" (people of Spanish background). In 1845, California Governor Pio Pico took land from Mission San Diego de Alcala. He gave about 48,800 acres of the El Cajon Valley to Dona Maria Antonio Estudillo. This was to pay back a $500 government debt.
This land was first called Rancho Santa Monica. It included what is now El Cajon, Bostonia, Santee, Lakeside, Flinn Springs, and part of La Mesa. Dona Maria Estudillo was married to Don Miguel Pedrorena. He was from Spain and came to California in 1838.
Becoming Part of the United States
After the Mexican–American War in 1848, California became part of the United States. The Treaty of Guadalupe Hidalgo said that the land grants would still be valid. In 1852, a claim for Rancho El Cajon was made for Pedrorena's children. It was approved by the U.S. Supreme Court in 1876.
In 1868, a land developer from Los Angeles, Isaac Lankershim, bought most of the Rancho El Cajon land. He hired Major Levi Chase to manage it. Chase received 7,624 acres, known as the Chase Ranch. Lankershim then hired Amaziah Lord Knox to manage Rancho El Cajon. In 1876, Knox opened a hotel there. This hotel served people traveling between San Diego and Julian, where gold had been found in 1869. A room and food for a guest and horse cost $1 a night.
The area became known as Knox's Corners. Later, it was renamed. By 1878, 25 families lived in the valley. A part of the hotel became the valley's post office, with Knox as the first postmaster.
Modern El Cajon
El Cajon officially became a city in 1912. For the first half of the 1900s, El Cajon was known for growing grapes, avocados, and citrus fruits.
In the 1960s and 1970s, there was a fun tourist spot called Frontier Town, Big Oak Ranch. It was a theme park that looked like an old frontier town. It even had pretend shootouts! The park closed around 1980. Now, homes are built there.
Cajon Speedway was a 70-acre race track. It was open from 1961 to 2005. It was known as "The fastest 3/8-mile paved oval in the West." Even though it closed, it's now a historic museum. You can see the original entrance sign there.
Where is El Cajon?
El Cajon covers about 14.4 square miles (37.3 square kilometers) of land. It is next to San Diego and La Mesa to the west. To the south is Spring Valley. To the north is Santee. Unincorporated parts of San Diego County are to the east. Some neighborhoods in El Cajon include Fletcher Hills, Bostonia, and Rancho San Diego.
El Cajon's Weather
El Cajon has a mix of a Mediterranean climate and a semiarid climate. This means it has mild, wet winters and hot, dry summers. The weather can change a lot over short distances. This is called a microclimate. El Cajon's weather is more extreme than coastal San Diego. The farther east you go from the coast, the drier it gets.
Temperatures usually change moderately between day and night. The average difference is about 24°F (13°C) in summer and 26°F (14°C) in winter.
El Cajon gets about 11.63 inches (295 mm) of rain each year. Most of the rain falls in winter, and it's rare in summer. February is usually the wettest month.
The highest temperature ever recorded was 114°F (46°C) on September 5, 2020. The lowest was 19°F (-7°C) on January 8, 1913. It rarely snows, but 0.3 inches (0.8 cm) fell in November 1992. In January 1882, 3 inches (8 cm) of snow covered the ground!
