About Marysville

Marysville is the county seat of Yuba County, California, United States. The population was 12,072 at the 2010 census, down from 12,268 at the 2000 census. It is included in the Yuba City Metropolitan Statistical Area, often referred to as the Yuba-Sutter Area after the two counties, Yuba and Sutter. The metropolitan statistical area is part of the Greater Sacramento area.

Marysville is 40 miles north of Sacramento and located in the Sacramento Valley. The city is bordered on the south and east by the Yuba River and the west by the Feather River, with the two rivers converging just southwest of the city. In years of significant snow runoff from the nearby Sierra Nevada range or heavy rain from winter storms, these two rivers pose a serious flooding risk to the city.

Marysville has a Mediterranean Climate, which is mild, wet winters and hot, dry summers. January is usually the wettest month. July is the driest and hottest. The wet season starts from mid-October and ends in mid-April when Yuba City sees frequent rain and is usually under the tule fog. Heavy rain, especially during El Niño or too much mountain snow from winter storms can cause major flooding in the spring. Snow is rare in the valley, but cold waves from the north bring some light snow and ice. Spring is wet in the beginning but becomes dryer and warmer as summer months approach. April is the wettest spring month. May has some rain, but usually from thunderstorms than winter storms. Spring orchards and fields become filled with flowers and tree blossoms during Spring. June-to-September is the dry and hot season. Rain usually doesn't fall at all, but from rare southwest monsoon thunderstorms. July and August are the hottest months when temperatures reach the upper 90's. Heat waves usually occur from June through September. The hottest months are July and August. The delta breeze, which comes from the Bay Area on summer nights, helps cool temperatures and add humidity. At times the delta breeze is strong enough to bring coastal fog inland to the Sacramento Valley. Autumn starts out warm but begins to become cooler, wetter, and foggier. From September-to-mid-October temperatures begin to cool down rapidly bringing rain and fog. Rain and fog become more persistent from mid-October into November.
