The 2009 California wildfires were a series of 9,159 wildfires that were active in the US state of California, during the year 2009. The fires burned more than 422,147 acres of land from early February through late November, due to Red Flag conditions, destroying hundreds of structures, injuring 134 people, and killing four. The wildfires also caused at least US$134.48 million in damage. Although the fires burned many different regions of California in August, the month was especially notable for several very large fires which burned in Southern California, despite being outside of the normal fire season for that region.
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, 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 in damage.
The Poinsettia Fire was the second most destructive of the May 2014 San Diego County wildfires. It caused property damage estimated at $22.5 million, as well as the only reported fatality in the San Diego County series of wildfires. As of July 10, 2014, the cause of the fire is listed as "undetermined", which allows for further investigation if more information comes to light.
The May 2014 San Diego County wildfires were a swarm of 20 wildfires that erupted during May 2014, in San Diego County, California, 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 Bernardo Fire has been declared accidental, and officials believe the Cocos Fire was intentionally set.

Six injuries and one fire-related fatality were reported.

Property damage from the fire is estimated at more than $5.7 million. Three minor injuries have been reported.
