2014 saw several notable wildfires igniting in California, especially during the month of May, when multiple fires were ablaze concurrently in Southern California, and during September, when several massive wildfires were burning in Northern California. In the context of the 2012–13 North American drought (especially the 2011–17 California drought), as well as powerful Santa Ana winds, weather conditions were ideal for wildfires. A total of 7,865 wildfires ignited throughout the year, which burned at least 625,540 acres (2,531.5 km²) of land. The wildfires caused a total of 146 injuries and 2 fatalities, in addition to causing at least $204.05 million (2014 USD) in damage.

The season began unusually early when a wildfire ignited on January 1, followed by 6 more fires igniting later within the same month. During a heat wave and dry Santa Ana conditions in May 2014, multiple wildfires broke out simultaneously in San Diego County, along with several other wildfires elsewhere in California. By mid-May, fire officials said they had already dealt with 1,400 wildfires in California in 2014 - twice the normal amount for that time of year - and a spokesman for CAL FIRE described the conditions as "unprecedented." The May 2014 San Diego County wildfires were estimated to have caused at least $60 million (2014 USD) in damage. In late June to early August, another group of wildfires ignited across the state, some of which reached over twenty thousand acres in size. In mid-September, the largest group of wildfires erupted, with some wildfires becoming larger than 50,000 acres in size. In early September 2014, the Happy Complex Fire became the largest wildfire of the season, eventually topping out at 135,369 acres (54,782 ha) in size on September 27. On October 8, an aerial tanker crashed during a firefighting effort at the Dog Rock Fire, which killed the pilot and sparked a small wildfire. From late September to late October, the latest flare-up of major wildfires were extinguished by cooler weather and precipitation.

From December 10–13, a powerful winter storm extinguished the remaining wildfires that were present. In mid-December through late December, several more small wildfires sparked, but they were all extinguished by December 31.

In 2014, a study examined the human role in growing California wildfire risks. The paper is titled "Extreme fire season in California: A glimpse into the future?" It was published as the second chapter of "Explaining Extreme Events of 2014", by the American Meteorological Society. The authors also projected into the future, and the predicted results showed increases in the drought index, the area under extreme threat of fires, and the days of fire danger, stating that, "The increase in extreme fire risk is expected within the coming decade to exceed that of natural variability and this serves as an indication that anthropogenic climate warming will likely play a significant role in influence California’s fire season."

The timing of "fire season" in California is variable, depending on the amount of prior winter and spring precipitation, the frequency and severity of weather such as heat waves and wind events, and moisture content in vegetation. Northern California typically sees wildfire activity between late spring and early fall, peaking in the summer with hotter and drier conditions. Occasional cold frontal passages can bring wind and lightning. The timing of fire season in Southern California is similar, peaking between late spring and fall. The severity and duration of peak activity in either part of the state is modulated in part by weather events: downslope/offshore wind events can lead to critical fire weather, while onshore flow and Pacific weather systems can bring conditions that hamper wildfire growth.

Below is a list of all fires that exceeded 1,000 acres (400 ha) during the 2014 California wildfire season, as well as the fires that caused significant damage. The list is taken from CAL FIRE's list of large fires.

In May 2014, a series of at least 20 wildfires broke out in San Diego County during severe Santa Ana Wind conditions, historic drought conditions, and a heat wave. The main event during mid-May was preceded by a precursor fire that ignited on May 5. The severe weather conditions contributed to the spread of at least 19 more individual wildfires, with ten of them receiving names. The Cocos Fire, which was the most destructive with 40 structured being destroyed, was determined to have been caused by arson. The causes of the other fires are still under investigation by multiple agencies, and a joint task force was formed to coordinate the investigations and facilitate communications. Six injuries and one fire-related fatality were reported.

At 2:00 PM PDT on May 13, the Miguelito Fire broke out off Santa Miguelito Canyon Road in Lompoc, Santa Barbara County. Over the course of the next week and a half, the fire gradually expanded northward to 632 acres (256 ha) towards the direction of Lompoc, before firefighters managed to stop its expansion on May 16. The fire threatened 1,200 buildings in Lompoc, prompting evacuation orders for the affected areas. On May 16, evacuation orders were lifted, after the fire was reported to be 95% contained. At 9:20 AM PDT on May 19, the Miguelito Fire was reported to be 100% contained. No structural damage or injuries were reported.
