Yuma (Cocopah: Yuum) is a city in and the county seat[4] of Yuma County, Arizona, United States. It is located in the southwestern corner of the state, and the population of the city was 93,064 at the 2010 census, up from the 2000 census population of 77,515.[2]

Yuma is the principal city of the Yuma, AZ Metropolitan Statistical Area, which consists of Yuma County. According to the United States Census Bureau, the 2013 estimated population of the Yuma MSA is 201,201,[5] though more than 85,000 retirees make Yuma their winter residence.[6]

Yuma Crossing in 1886. The railway bridge over the Colorado River was built in 1877.

The area's first settlers were Native American tribes whose descendants now occupy the Cocopah and Quechan reservations. In 1540, expeditions under Hernando de Alarcon and Melchior Diaz visited the area and immediately saw the natural crossing of the Colorado River as an ideal spot for a city, as the Colorado River narrows to slightly under 1,000 feet wide in one small point. Later military expeditions that crossed the Colorado River at the Yuma Crossing include Juan Bautista de Anza (1774), the Mormon Battalion (1848) and the California Column (1862).

Following the establishment of Fort Yuma, a town sprang up on the New Mexico Territory (now Arizona) side of the Colorado. The townsite was duly registered in San Diego, demonstrating that both banks of the Colorado River just below its confluence with the Gila were recognized as being within the jurisdiction of California. The county of San Diego collected taxes from there for many years.[7] The town, initially called Colorado City, was renamed Arizona City in 1858. The city was almost completely destroyed by the Great Flood of 1862 and had to be rebuilt on higher ground.[8] It took the name Yuma in 1873.

From the 1850s to the 1870s, the Yuma Crossing was known for its ferry crossing. From 1852 it was the major steamboat stop on the way up and down the Colorado River. The steamboats transported passengers and equipment for the various mines and military outposts along the Colorado and was the terminus of wagon traffic up the Gila River into New Mexico Territory. They offloaded the cargo from ships at the mouth of the Colorado River at Robinson's Landing and from 1864 at Port Isabel. From 1864, the Yuma Quartermaster Depot, today a state historic park, supplied all forts in present-day Arizona, as well as large parts of Colorado and New Mexico. Yuma served as the gateway to the new Republic (later State) of California, as it was one of the few natural spots where travelers could cross the otherwise very wide Colorado River. After Arizona became a separate territory, Yuma became the county seat for the area in 1864.

The Southern Pacific Railroad bridged the river in 1877, and acquired George Alonzo Johnson's Colorado Steam Navigation Company, the only steamboat company on the river. Yuma became the head of navigation on the river, ending the need for Port Isabel, which was abandoned in 1879.


Yuma is located at 32°41′32″N 114°36′55″W / 32.69222°N 114.61528°W / 32.69222; -114.61528 (32.692148, −114.615389),[9] near the borders of California to the west and Mexico to the south, and just west of the Gila River's confluence with the Colorado. The city is approximately 60 miles from the Gulf of California (Sea of Cortez), a branch of the Pacific.

According to the United States Census Bureau, the city has a total area of 106.7 square miles (276 km2), of which 106.6 square miles (276 km2) is land and 0.1 square miles (0.26 km2) (0.07%) is water.


Yuma is noted for its weather "extremes". Of any populated place in the contiguous United States, Yuma is the driest, sunniest, and least humid; has the lowest frequency of rain and snow; and has the most number of days per year–175–with a daily maximum temperature of 90 °F (32 °C) or higher.[10][11]

The sun shines for about 90 percent of the days in Yuma, making it the sunniest place on Earth. The city experiences an average of 4015 hours of sunshine per year, and 11.0 hours of sunshine per day.[11][12] The near-perfect weather for flying year-round attracts military interest in training their pilots here.[citation needed]

Yuma features a subtropical desert climate (Köppen climate classification BWh), with extremely hot summers and warm winters. Humidity is usually low except during what are called "gulf surges", when a moist air mass from the Gulf of California is drawn northward, usually in connection with the summer monsoon or the passage of a tropical storm to the south.

On average, Yuma receives 3.36 inches (85 mm) of rain annually, and even in the wettest year of 2005, only 7.39 in (188 mm) fell. The driest year at Yuma Airport has been 2007 with only 0.15 in (3.8 mm). August is the wettest month of the year, while June is the driest.

On July 28, 1995, Yuma reached its all-time high of 124 °F (51 °C). The lowest recorded temperature fell to 13 °F (−11 °C) on the Yuma-Mesa area in January 2007. The temperature fell to 13 °F (−11 °C) for approximately two hours and was deleterious to the many crops grown in and around Yuma. The crop that suffered the most damage was the citrus on the Yuma mesa, most notably the lemon crop which suffered a 75% to 95% loss of crop and trees as stated by the Arizona Department of Agriculture in a February 2007 report. On average, the temperature lowers to the freezing mark in less than a quarter of years, and there are 118 days per year that reach or exceed 100 °F (38 °C), usually from April through October, and during July and August fails to reach the century mark on at most a few days.

In 1997, the desert city sustained a full tropical storm after Hurricane Nora made landfall at the mouth of the Colorado River and quickly moved due north along it. This rare event cut power to 12,000 customers in Yuma, and dropped 3.59 inches (91 mm) of rain at Marine Corps Air Station Yuma. The last time a hurricane had hit near Yuma was in mid-August 1977, when similar falls were recorded.[citation needed]

The high poverty rate may be due to unemployment.

High unemployment remains an issue in Yuma. Citing April 2014 data, the Bureau of Labor Statistics ranked Yuma as having the highest unemployment rate in the United States at 23.8 percent, above the 21.6 percent in El Centro, California.[17] Yuma's agricultural workforce, which adjusts to the picking season, is cited as the reason for the high unemployment by the Arizona Department of Commerce.[18]
