Malibu's eastern end borders the
community of Topanga, which separates it from the city of Los Angeles. According to the
United States Census Bureau, the city has an area of , over 99% of it is land. Malibu's dry brush
chaparral and steep clay slopes make it prone to fires, floods, and mudslides. Beaches on the Malibu coast include Big Rock Beach, Broad Beach,
County Line Beach, Dan Blocker Beach, La Costa Beach, Las Flores Beach, Malibu Beach,
Point Dume Beach,
Surfrider Beach,
Topanga Beach, and
Zuma Beach. State parks and beaches on the Malibu coast include
Leo Carrillo State Beach and Park,
Malibu Creek State Park,
Point Mugu State Park, and
Robert H. Meyer Memorial State Beach, along with individual beaches such as El Matador Beach, El Pescador Beach, La Piedra Beach, Carbon Beach, Surfrider Beach, Westward Beach, and Escondido Beach. Paradise Cove, Pirates Cove, Trancas, and Encinal Bluffs are along the coast in Malibu.
Point Dume forms the northern end of the
Santa Monica Bay, and Point Dume Headlands Park affords a vista stretching to the
Palos Verdes Peninsula and
Santa Catalina Island. Like all California beaches, Malibu beaches are public below the mean high tide line. Many large public beaches are easily accessible, but such access is sometimes limited for some of the smaller and more remote beaches. The Malibu Coast lies on the fringe of an extensive
chaparral and woodland wilderness area, the Santa Monica Mountains National Recreation Area. Various environmental elements collectively create a recipe for
natural disasters: the mountainous and geologically unstable terrain; seasonal rainstorms that result in dense vegetation growth; seasonal dry
Santa Ana winds; and a naturally dry topography and climate.
Wildfires , seen from the
Pacific Coast Highway The Malibu coast has seen dozens of wildfires: • October 26, 1929 – Malibu Colony, 13 homes burned. • October 14, 1985 – "Piuma," Las Flores area, Topanga Canyon, . The 1993 firestorm was composed of two separate fires, one ravaging most of central Malibu/Old Topanga, and another, larger fire affecting areas north of Encinal Canyon. Three people died and 739 homes destroyed in the central Malibu/Old Topanga blaze. were torched in the north Malibu fire, with no deaths and few homes destroyed in the less densely populated region. Los Angeles County Fire Department officials announced suspicions that the fire was started by arson. The fire and widespread damage to properties and infrastructure resulted in the City of Malibu adopting the strictest fire codes in the country. • October 21, 1996 – "Calabasas," Malibu Canyon Corridor, Brush fire ignited by arcing power line, . • January 6, 2003 – "Trancas", Trancas Canyon, . • January 8, 2007 – At about 5:00 pm a fire started in the vicinity of Bluffs Park, south of
Pacific Coast Highway in Malibu. The fire hit near the Colony area, burning down four houses on Malibu Road, including the oceanfront home of
Step By Step star
Suzanne Somers. The
Los Angeles County Fire Department announced that a discarded cigarette stub started the blaze. • October 21, 2007 – At about 5:00 am a fire started off of
Malibu Canyon Road. As of 1:00 pm there were 500+ personnel on scene. burned with no containment. 200+ homes were evacuated. Five homes were confirmed to have been destroyed, with at least nine others damaged. Two commercial structures were completely destroyed. Castle Kashan and the Malibu Presbyterian Church were both destroyed. • November 24, 2007 – The "Corral Fire" destroyed 53 homes, damaged 35, and burned over , forcing as many as 14,000 people to evacuate. Damages from the fire were expected to reach more than $100 million. The blaze originated at the top of Corral Canyon, where a group of young people who were in closed parkland after dusk had started a bonfire despite the presence of high Santa Ana winds. The individuals responsible for starting the fire were later identified, and are the subject of ongoing civil and criminal litigation. • November 8, 2018 – The
Woolsey Fire, a wildfire that burned from November 8–21 that burned and destroyed 1,500 structures and left 341 buildings damaged. The fire also resulted in 3 firefighter injuries and 3 civilian fatalities. In 2020, authorities blamed faulty
Southern California Edison equipment for the blaze. • December 9, 2024 – The
Franklin Fire began shortly before 11:00 pm on December 9 near Malibu Canyon Road. The fire spread quickly under strong Santa Ana winds, burning a total of over the next few days. The fire prompted mandatory evacuations for much of Malibu and destroyed a total of 19 structures. • January 7, 2025 – The
January 2025 Southern California wildfires caused deaths, evacuations, and heavy damage to homes and property, including in Malibu. The
Palisades Fire began around 10:30 a.m. on January 7 and initially burnt nearly 3,000 acres between Santa Monica and Malibu. The uncontrollable blaze, which continued to consume buildings, has wound up burning more than 11,000 acres between the two beach towns.
Mudslides One of the most problematic side effects of the fires that periodically rage through Malibu is the destruction of vegetation, which normally provides some degree of topographical stability to the loosely packed shale and sandstone hills during periods of heavy precipitation.
Rainstorms following large wildfires can thus cause mudslides, in which water-saturated earth and rock moves quickly down mountainsides, or entire slices of mountainside abruptly detach and fall downward. After the 1993 wildfire stripped the surrounding mountains of their earth-hugging
chaparral, torrential rainstorms in early 1994 caused a massive mudslide near Las Flores Canyon that closed down the Pacific Coast Highway for months. Thousands of tons of mud, rocks, and water rained down on the highway. The destruction to property and infrastructure was exacerbated by the road's narrowness at that point, with beachside houses abutting the highway with little or no frontage land as a buffer to the mudslide. Another large mudslide occurred on
Malibu Canyon Road, between the
Pepperdine University campus and HRL Laboratories LLC, closing down Malibu Canyon for two months. Yet another behemoth slide occurred on
Kanan Dume Road, about up the canyon from the
Pacific Coast Highway. This closure lasted many months, with Kanan finally fixed by the
California Department of Transportation (Cal-Trans) over a year after the road collapsed. Mudslides can occur at any time in Malibu, whether a recent fire or rainstorm has occurred or not. Pacific Coast Highway,
Kanan Dume Road, and
Malibu Canyon Road, as well as many other local roads, have been prone to many subsequent mudslide-related closures. During any period of prolonged or intense rain, Caltrans snowplows patrol most canyon roads in the area, clearing mud, rocks, and other debris from the roads. Such efforts keep most roads passable, but it is typical for one or more of the major roads leading into and out of Malibu to be temporarily closed during the rainy season.
Storms Malibu is periodically subject to intense coastal storms. Occasionally, these unearth remnants of the
Rindge railroad that was built through Malibu in the early 20th century. On January 25, 2008, during an unusually large storm for Southern California, a tornado came ashore and struck a naval base's hangar, ripping off the roof. It was the first
tornado to strike Malibu's shoreline in recorded history.
Earthquakes Malibu is within of the
San Andreas Fault, a fault over long that can produce an earthquake over magnitude 8. Several faults are in the region, making the area prone to earthquakes. The
1971 Sylmar earthquake and the 1994
Northridge earthquake (magnitudes 6.6 and 6.7, respectively) shook the area. Smaller earthquakes happen more often.
Climate This region experiences warm and dry summers, with no average monthly temperatures above . According to the
Köppen Climate Classification system, Malibu has a
warm-summer Mediterranean climate, abbreviated "Csb" on climate maps. The city's climate is influenced by the Pacific Ocean, resulting in far more moderate temperatures than locations further inland experience. Snow in Malibu is extremely rare, but flurries with higher accumulations in the nearby mountains occurred on January 17, 2007. More recently, snow fell in the city on January 25, 2021. The record high temperature of was observed on September 27, 2010, while the record low temperature of was observed on January 14, 2007. ==Demographics==
