Why El Cajon
Located 17 miles east of downtown San Diego in Southern California, El Cajon is an inland city situated within a valley basin. Covering an area of 14.4 square miles, the municipality takes its name from a Spanish phrase meaning "the box" or "the drawer," referring to the boxed-in physical geography created by the surrounding terrain. The city is bounded by San Diego and La Mesa to the west, Santee to the north, Spring Valley to the south, and unincorporated county lands to the east. Key residential districts within its borders include Fletcher Hills, Bostonia, and Rancho San Diego.
El Cajon features an arid Mediterranean climate marked by distinct microclimates and greater daily temperature swings than coastal sections of San Diego County. Typical day-to-night temperature variations average 24 degrees Fahrenheit in the summer and 26 degrees in the winter. Annual rainfall averages approximately 11.6 inches, with the vast majority of precipitation arriving during the winter season—especially in February—while summer rainfall is minimal.
The area's recorded development dates to the Spanish colonial era, when mission padres used the naturally enclosed valley as pastureland for cattle. Under Mexican governance in 1845, the valley was granted as Rancho El Cajon. Following the region's transfer to the United States and the 1869 gold rush in nearby Julian, hotel owner Amaziah Lord Knox set up a waystation for travelers in 1876, creating a community initially known as Knox's Corners. Rail service arrived during the 1880s, leading to the city's formal incorporation in 1912. Throughout the first half of the 20th century, the local economy relied prominently on agriculture, specializing in grapes, avocados, and citrus groves.
Today, El Cajon supports a population of over 100,000 residents and is recognized for its cultural diversity, including substantial communities of Iraqi Americans and Chaldean Catholics. Historical points of interest include the site of the former Cajon Speedway, a paved 3/8-mile stock car track that operated from 1961 to 2005 and now functions as a historic museum displaying its original entryway signage.
