Yuba City has a hot-summer mediterranean climate (Csa according to the Köppen climate classification system) which consists of cool, wet winters and hot, dry summers.On average, January is the coolest and wettest month, and July is the hottest and driest.The Christmas Eve levee break at Yuba City was particularly disastrous, with 38 people losing their lives, and heavy damage occurring in the downtown section.According to Dick Brandt, manager of the Yuba County airport in 1955, between 550 and 600 Sutter County residents were rescued from the floodwater by helicopter.One version of the origin of the name "Yuba" is that during one of these expeditions, wild grapes were seen growing by a river, and so it was named "Uba", a variant spelling of the Spanish word uva (grape).The Mexican government granted a large expanse of land which included the area in which Yuba City is situated to John Sutter, the same John Sutter upon whose land gold was subsequently discovered in 1848.The racial makeup of Yuba City was 37,382 (57.6%) White, 1,591 (2.5%) African American, 909 (1.4%) Native American, 11,190 (17.2%) Asian, 228 (0.4%) Pacific Islander, 9,772 (15.1%) from other races, and 3,853 (5.9%) from two or more races.Hispanic or Latino of any race were 18,413 persons (28.4%).
The Maidu people were settled in the region when they were first encountered by Spanish and Mexican scouting expeditions in the early 18th century.
The unemployment rate in the Yuba City MSA was 14.9 percent in September 2012, down from a revised 15.8 percent in August 2012, and below the year-ago estimate of 16.4 percent.
This compares with an unadjusted unemployment rate of 9.7 percent for California and 7.6 percent for the nation during the same period.
In December 1955, a series of storms dropped torrential rain throughout northern California.
The deluge caused all the rivers in the region to overflow their banks and to break through levees.
