The 2023 California wildfire season was a series of significant wildfires that burned in the U.S. state of California during the calendar year. According to statistics published by the California Department of Forestry and Fire Protection (Cal Fire), a total of 7,127 fires burned a total of 324,917 acres (131,489 hectares). This was below the state's five-year average of 1,722,059 acres (696,893 ha) burned during the same period. [1] [2] The 2023 fire season followed the 2022 season, during which the number of fires and the resulting burned acreage were both below average. [3] Four fatalities were reported during the 2023 fire season. [4]
California saw a series of powerful atmospheric rivers between December 2022 and March 2023, which much improved drought conditions in the state and boosted the snowpack in the Sierra Nevada to more than 200% of average for the date. Some researchers noted that the resulting vegetation growth could prove dangerous if dry and warm conditions return during spring and summer, obviating the gains from early storms, [5] [6] but in general, according to the California Department of Forestry and Fire Protection (Cal Fire), increased precipitation reduces the risk of a worse wildfire season. [7]
Cal Fire predicted that "critically dry fuel moisture alignments are not likely to be reached for any great length of time or over a larger area" between March and June 2023. [1] Critical fuel moisture refers to the point at which fuel characteristics—like vegetation mortality or dryness—are favorable for large fire growth. [8] [7] [9]
In Northern California, fire season typically peaks in the summer with increasingly warm and dry conditions and aided by occasional dry cold frontal passages that may bring winds and/or lightning. Activity usually continues until late fall brings Pacific moisture to the northern portion of the state, though northeast wind events may pose a threat. In Southern California, fire season typically peaks in late spring through early fall, when Pacific moisture recedes. Offshore wind events such as Santa Ana winds mean that large fires are possible year-round, but their frequency is most heightened in the fall, when fuels are also driest. [10]
In January, U.S. Agriculture Secretary Tom Vilsack announced the allocation of $930 million in funding from the Infrastructure Investment and Jobs Act and the Inflation Reduction Act to 10 western states, including California, for fuel reduction programs and other measures to curtail wildfire risks. [11] The allocation was reported to represent a significant increase in funding for programs like tree clearing, brush thinning and removal, and controlled burns in Southern California, whose four National Forests previously received about $1.2 million annually for those purposes. [12]
On January 31, California senators Dianne Feinstein and Alex Padilla (as well as senators Steve Daines of Montana and Ron Wyden of Oregon) introduced a bill to the U.S. Senate entitled the Wildfire Emergency Act, recognizing the "threat of wildfire" as an emergency in the Western United States. The proposed bill would provide at least a quarter of a billion dollars in funding for forest restoration and wildfire resilience in 20 locations of more than 100,000 acres (40,000 ha) each, coordinated by the Forest Service. It would also create a program at the Department of Energy to "ensure that critical facilities remain active during wildfire disruptions". Further funding would be provided for prescribed fire implementation, firefighter training, and wildfire detection. [13]
On March 20, Vice President Kamala Harris announced $197 million in federal grants through the administration’s wildfire defense grant program. [14] California-based authorities and organizations were slated to receive 29 grants; they include money for counties to conduct home defensible space inspections, prescribed burn training, and fuels reductions, as well as increased funding for U.S. Forest Service and Department of Interior wildfire prevention efforts. [15]
While fighting the three-acre (1.2 ha) Broadway Fire near Cabazon in Riverside County on August 6, two helicopters (a Bell 407 and a Sikorsky S-64E) collided in mid-air. The Sikorsky helicopter landed safely, while all three occupants of the Bell helicopter—a contract pilot, a Cal Fire division chief, and a Cal Fire captain—were killed. The National Transportation Safety Board (NTSB) will investigate the accident. [16] [17] The state of California reported four fatalities during the 2023 fire season, including three firefighters and one civilian. [18]

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.
The 2015 California wildfire season was a series of wildfires that burned across the state of California. By the end of 2015 a total of 8,745 fires were recorded, burning 893,362 acres (3,615 km2) across the state. Approximately 3,159 structures were damaged or destroyed by wildfires, and at least 7 fatalities were recorded.
The Rough Fire was a major wildfire in Fresno County, California, and the largest of the 2015 California wildfire season. The fire was ignited by a lightning strike on July 31 and burned 151,623 acres (61,360 ha), largely in the Sierra National Forest and the Sequoia National Forest, before it was declared contained on November 6, 2015. At the time it occurred, the fire was the thirteenth largest in recorded California history.
In 2016, a total of 7,349 fires had burned an area 669,534 acres (2,709.51 km2) in California, according to the California Department of Forestry and Fire Protection.
The Soberanes Fire was a large wildfire that burned from July to October 2016 in the Santa Lucia Mountains of Monterey County, California. It destroyed 57 homes and killed a bulldozer operator, and cost about $260 million to suppress, making it at the time the most expensive wildfire to fight in United States history. At the fire's peak, over 5,000 personnel were assigned to the blaze. The fire was the result of an illegal campfire in Garrapata State Park. By the time it was finally extinguished, the fire had burned 132,127 acres (53,470 ha) along the Big Sur coast in the Los Padres National Forest, Ventana Wilderness, and adjacent private and public land in Monterey County, ranking it 18th on the list of the largest California wildfires in terms of acreage burned.
In terms of property damage, 2017 was the most destructive wildfire season on record in California at the time, surpassed by only the 2018 season and the 2020 season, with a total of 9,560 fires burning 1,548,429 acres (6,266.27 km2) of land, according to the California Department of Forestry and Fire Protection, including five of the 20 most destructive wildland-urban interface fires in the state's history. Throughout 2017, the fires destroyed or damaged more than 10,000 structures in the state, a higher tally than the previous nine years combined. State data showed that the large wildfires killed 47 people – 45 civilians and 2 firefighters – almost higher than the previous 10 years combined. The total property damage and total amount of burned land were both surpassed by the 2018 California wildfires.
The 2019 California wildfire season was a series of wildfires that burned across the U.S. state of California as part of the 2019 wildfire season. By the end of the year, according to Cal Fire and the US Forest Service, 7,860 fires were recorded, totaling an estimated of 259,823 acres of burned land. These fires caused 22 injuries, 3 fatalities, and damaged or destroyed 732 structures. The 2019 California fire season was less active than that of the two previous years, which set records for acreage, destructiveness, and deaths.
The 2020 California wildfire season, part of the 2020 Western United States wildfire season, was a record-setting year for wildfires in California. Over the course of the year, 8,648 fires burned 4,304,379 acres (1,741,920 ha), more than four percent of the state's roughly 100 million acres of land, making 2020 the largest wildfire season recorded in California's modern history. However, it is roughly equivalent to the pre-1800 levels which averaged around 4.4 million acres yearly and up to 12 million in peak years. California's August Complex fire has been described as the first "gigafire", burning over 1 million acres across seven counties, an area larger than the state of Rhode Island. The fires destroyed over 10,000 structures and cost over $12.079 billion in damages, including over $10 billion in property damage and $2.079 billion in fire suppression costs. The intensity of the fire season has been attributed to a combination of more than a century of poor forest management and higher temperatures resulting from climate change.
The SCU Lightning Complex fires were wildfires that burned in the Diablo Range in California in August and September 2020 as part of the 2020 California wildfire season. The fire complex consisted of fires in Santa Clara, Alameda, Contra Costa, San Joaquin, Merced, and Stanislaus counties. The name is derived from the three-letter designation given to the California Department of Forestry and Fire Protection division responsible for the Santa Clara, Alameda, Contra Costa, and parts of San Joaquin and Stanislaus counties, and the complex consisted of several distinct fires occurring in this region.
The 2020 Creek Fire was a very large wildfire in central California's Sierra National Forest, in Fresno and Madera counties. One of the most significant fires of California's record-setting 2020 wildfire season, it began on September 4, 2020, and burned 379,895 acres (153,738 ha) over several months until it was declared 100% contained on December 24, 2020. The Creek Fire is the sixth-largest wildfire in recorded California history and the third-largest single fire—i.e. not part of a larger wildfire complex—following the 2021 Dixie Fire.
The Western United States experienced a series of major wildfires in 2020. Severe August thunderstorms ignited numerous wildfires across California, Oregon, and Washington, followed in early September by additional ignitions across the West Coast. Fanned by strong, gusty winds and fueled by hot, dry terrains, many of the fires exploded and coalesced into record-breaking megafires, burning more than 10.2 million acres of land, mobilizing tens of thousands of firefighters, razing over ten thousand buildings, and killing at least 37 people. The fires caused over $19.884 billion in damages, including $16.5 billion in property damage and $3.384 billion in fire suppression costs. Climate change and poor forest management practices contributed to the severity of the wildfires.
The 2021 California wildfire season was a series of wildfires that burned across the U.S. state of California. By the end of 2021 a total of 8,835 fires were recorded, burning 2,568,948 acres (1,039,616 ha) across the state. Approximately 3,629 structures were damaged or destroyed by the wildfires, and at least seven firefighters and two civilians were injured.
The Caldor Fire was a large wildfire that burned 221,835 acres in the Eldorado National Forest and other areas of the Sierra Nevada in El Dorado, Amador, and Alpine County, California, in the United States during the 2021 California wildfire season. The fire was first reported on Saturday, August 14, 2021, and was fully contained on Thursday, October 21, 2021. The Caldor Fire destroyed 1,005 structures and damaged 81 more, primarily in the US Highway 50 corridor and in the community of Grizzly Flats, 2/3 of which was destroyed by the fire.
The 2022 California wildfire season was a series of wildfires throughout the U.S. state of California. By the end of the year, a total of 7,667 fires had been recorded, totaling approximately 363,939 acres across the state. Wildfires killed nine people in California in 2022, destroyed 772 structures, and damaged another 104. The 2022 season followed the 2020 and 2021 California wildfire seasons, which had the highest and second-highest (respectively) numbers of acres burned in the historical record, with a sharp drop in acreage burned.
The Red Fire was a wildfire that burned in Yosemite National Park, Mariposa County, during California's wildfire season in 2022. Lightning started the fire, which was then discovered on August 4. The fire burned 8,364 acres (3,385 ha) before it was declared completely contained on September 20. The Red Fire burned within the footprint of the 2001 Hoover Fire.
This article is a summary of the 2023 Oregon wildfire season, comprising the series of significant wildfires that have burned in the U.S. state of Oregon since the beginning of the calendar year. Fire season officially began in all areas of the state by July 1, according to the Oregon Department of Forestry (ODF). As of September 5, 2023, the state had recorded 1,731 fires, which had burned a total of 159,991 acres.
This is a list of wildfires across the United States during 2024, that have burned more than 1,000 acres, produced significant structural damage or casualties, or otherwise been notable. Acreage and containment figures may not be up to date.
The 2024 California wildfire season is an ongoing series of wildfires that have been burning throughout the U.S. state of California. As of November 10, 2024, a total of 7,558 wildfires have burned a cumulative 1,040,546 acres (421,094 ha). Year-to-date, the number of wildfires and the number of acres burned are higher than the five-year average. Wildfires have destroyed 1,437 structures and killed one person in the state in 2024. The severity of this season with regards to acres burnt has not been seen since the 2021 season.
The 2024 Wildcat Fire was a relatively large wildfire that burned in the Tonto National Forest, located in the U.S. state of Arizona. The fire burned 14,402 acres of land before being declared contained on June 3. It was the second-largest wildfire of the 2024 Arizona wildfire season, only behind the Freeman Fire.
The 2024 Kern County wildfires are a series of active major and non-major wildfires burning in Kern County, California. The fires began in the month of April and remain active. So far, in the year 2024, California saw one of its worse fire seasons in California compared to recent years. Due to the high amount of precipitation that had fallen the previous winter, there was an overabundance of dry fuels that make it easier for large fires to start. High winds were also present during the summer when fire season is mostly active in the state. This led to the wildfires in Kern County to be destructive and costly.
