The Lilac Fire was a fire that burned in northern San Diego County, California, United States, and the second-costliest one of multiple wildfires that erupted in Southern California in December 2017. The fire was first reported on December 7, 2017, burned 4,100 acres (1,659 ha), and destroyed 157 structures, before it was fully contained on December 16. The fire cost at least $8.9 million (2018 USD), including $5 million in firefighting expenses and property damage, and an additional $3.9 million in cleanup and erosion control costs. The fire threatened the communities of Bonsall, Oceanside, Vista, Fallbrook, and Camp Pendleton. During the fire, an estimated 10,000 residents were forced to evacuate, while a total of over 100,000 residents were forced to or advised to evacuate. On December 7, the Lilac Fire also cut the power to 20,000 people.
The Lilac Fire was reported on December 7, 2017, at 11:15 am PST, as a small brush fire, just off Interstate 15. The fire was spotted near Old Highway 395 and Dulin Road, near the intersection between State Route 76 and Interstate 15, in Bonsall, San Diego County, California. Fanned by unusually powerful Santa Ana winds, with gusts reaching 66 mph (106 km/h), the wildfire quickly grew in size; within minutes, the wildfire grew to 50 acres. By 11:35 AM PST, the Lilac Fire had reached 500 acres (200 ha). The winds pushed the fire west towards Oceanside and Vista. During that afternoon, the Lilac Fire left nearly 20,000 San Diego Gas & Electric customers without power. The Lilac Fire expanded to 4,100 acres (1,659 ha) by the evening, with 0% containment. Around that time, there were concerns that the Lilac Fire could burn all the way to the Pacific Ocean, near Camp Pendleton.
On the day the fire was reported, Governor Jerry Brown declared a state of emergency for San Diego County, due to the fire, stating, “The fire is very dangerous and spreading rapidly, but we’ll continue to attack it with all we’ve got. It's crucial residents stay ready and evacuate immediately if told to do so.”
Cal State San Marcos, Palomar College, and MiraCosta College canceled classes and closed for the rest of the week. Mandatory evacuations were issued for areas of Bonsall and Oceanside, California. Cal Fire reports that "the fire is growing at a dangerous rate of spread with structures threatened." Three people were injured, including two horse handlers who suffered burns and a deputy from the San Diego County Sheriff's Department who was injured while directing traffic. The fire burned the San Luis Rey Training Center, destroying eight barns and killing 46 horses.
On the morning of December 8, the fire remained at 4,100 acres (1,700 ha) and 0% containment, and 105 buildings had been destroyed. One more civilian and a firefighter were hospitalized due to smoke inhalation, and another firefighter was treated for a dislocated shoulder. Later that evening, a shift in the wind direction and an increase in humidity allowed firefighters to make progress on the fire, increasing containment of the fire to 15%. During the evening, the Santa Ana winds returned to the region. During the afternoon of December 9, a woman was arrested for looting a home in Bonsall, within the mandatory evacuation zone.
On December 10, the Lilac Fire's burn area remained at 4,100 acres (1,659 ha), with containment increasing to 75%. Assessments revealed that the fire had destroyed 151 buildings, while damaging 56 others. Despite strong Santa Ana winds picking up again across Southern California and near the Lilac Fire, the winds failed to materialize around the Lilac Fire's burn area, which allowed firefighters to make significant progress on containing the fire. Firefighters strengthened containment lines with the help of good weather. Due to the increase in fire containment, and the waning Santa Ana winds, all evacuation orders and road closures for the Lilac Fire were lifted at about 4:00 PM PST on December 10. On December 11, the Lilac Fire was 90% contained, with no further increases in size.
On December 14, containment of the Lilac Fire had increased to 98%. During the early afternoon of Friday, December 15, smoke was spotted near the location where the Lilac Fire had started, under a bridge on Interstate 15. However, by 1:22 pm PST on the same day, CalFire reported that the situation had been brought under control.
Early on December 16, it was reported that the Lilac Fire had been fully contained, with the final burn area remaining at a size of 4,100 acres (1,700 ha).

After the Lilac Fire had started, authorities began investigating the source of the fire. Soon after the Lilac Fire had ignited, multiple motorists reported spotting a thin line of fire off Interstate 15, with the flames about 1 foot high and no longer than "a double-wide bed." Although investigators managed to narrow the origin point of the Lilac Fire down to a 1-square-foot area, they were unable to find anything that they could use to determine the fire's cause. Despite the many reports they received from motorists near the start of the fire, investigators were still unable to find a solid lead on the fire's cause. Investigators stated that the cause of the Lilac Fire may never be known without more tips from the public, but also stated that whoever started the fire may have done so unknowingly; a truck that was generating sparks from dragging a metal chain is a possible cause.
