The U.S. state of California experiences several tornadoes every year, with at least 488 twisters recorded since 1891. Among these are four fire whirls, a type of tornado that develops from a wildfire. California's strongest rated tornadoes on the Fujita scale (or Enhanced Fujita Scale after 2007) were rated an F/EF3, which occurred three times – two F3 tornadoes in the Greater Los Angeles area in the 1970s, as well as an EF3-equivalent fire whirl near Redding in Shasta County that developed within the 2018 Carr Fire. The fire whirl was one of three deadly tornadic events on record in the state, killing four people. A tornado in 1891 killed a man in San Francisco. The other deadly event was a tornado that hit Santa Monica in 1952, which killed three people. There have been at least 100 injuries related to tornadoes in the state.

Although less common and not as strong as tornadoes in the central United States, there are regularly tornadoes in three regions of the state – the Los Angeles area, the deserts of Southern California, and the Central Valley. Most tornadoes in California are weak and short-lived, often F0 or EF0, although some can be destructive or notable. Tornadogenesis can occur because of a supercell thunderstorm, a waterspout, a landspout, or a fire whirl, and can happen in any month of the year. The month with the most tornadic activity is March, with most of the state's tornadoes occurring between January and April. Excluding fire whirls, the most recent EF2 tornado was in 2011, which touched down near Oroville in Butte County. In July 2004, a twister touched down in Sequoia National Park at an altitude of around 12,156 ft (3,705 m), making it the highest elevation for a confirmed tornado in the United States. The most California tornadoes on a single day in the state was seven, which occurred on November 9, 1982. More recently, there were five tornadoes on April 1, 1996, as well as October 22, 2012.

In the United States, tornadoes develop less frequently west of the Rocky Mountains as compared to the rest of the continent. In the state of California, three areas more commonly experience tornadoes – in the Los Angeles area, in the deserts of Southern California, and the Central Valley. The Los Angeles area typically experiences more twisters than the rest of the state, and is among the most frequently affected areas in the United States west of the Rockies. California tornadoes are usually weak, categorized as an F0 or F1 on the Fujita scale, or an EF0 or EF1 after the Enhanced Fujita scale was implemented in 2007. Most twisters in the state are also short-lived, with an average path of 0.62 mi (1.00 km) and a width of 43 yd (39 m); this compares with Iowa tornadoes with an average path of 4 mi (6.4 km) and a width of 170 yd (160 m). The vast majority of California tornadoes occur between November and April, accounting for 80.2% of the state's tornadoes according to a 1993 survey. This is during the state's cooler period, which contrasts with the rest of the United States which experiences most of its tornadoes from April to June.

Along the Pacific coast, waterspouts occasionally develop over the ocean and move onshore. In addition, some tornadoes can develop from localized convergence zones known as landspouts, which are often weak and short-lived. Landspouts are the source of the majority of California tornadoes. On rare occasion, tornadoes can originate from supercells, which are more similar in nature to twisters across the Midwestern United States. Because of their irregular and short-lived nature, the San Diego National Weather Service considers it "nearly impossible to forecast a Southern California tornado before it touches down." The agency utilizes a volunteer group of more than 1,300 volunteers to report local severe weather.

In the Los Angeles area, Santa Ana winds can produce a convergence zone when they interact with Lake Elsinore, which can produce a line of thunderstorms capable of spawning a tornado. A similar phenomenon can occur on the north and east side of mountains extending north to Victorville. The location of the mountains relative to the coastline creates the favorable conditions for tornadogenesis in the Los Angeles Area. Due to the area's high population, even weak tornadoes can cause significant impacts. They mostly occur between September and May, not during the summer. Conversely, warm, tropical air can produce tornadoes in the deserts of southern California during the summer. In the Central Valley, tornadoes can form when the winds from a trough are perpendicular to the coastal range of mountains, bringing onshore moisture from the San Francisco area to the Sierra Nevadas. Tornadoes mostly occurred in March and April in the Central Valley.

Due to the large size of California, there is a likely undercount in the number of rural tornadoes. Also, due to the rare nature of tornadoes in the state, it is possible that some reported tornadoes were other weather events, such as a microburst, or straight-line winds.
