Cal Fire reports the blaze is 10 percent contained.
The fire started around 10:30 p.m. Friday, burning about 100 acres in the 3000 block of West Pacific Coast Highway. According to Ventura County Fire officials, the flames were visible about 150 feet from the sand.
More than 500 firefighters from various agencies, including Los Angeles County Fire Department and CalFire, worked to quell the flames.
Strong winds and dry, drought-stricken vegetation caused the fire to quickly grow to 900 acres by 5 a.m. Saturday, prompting mandatory evacuations for the Solimar Beach and Emma Wood State Beach areas. The blaze threatened about 35 structures in the Solimar Beach community.
Residents living in Faria Beach were placed under voluntary evacuations. The Red Cross set up a shelter in Carpinteria at the Veteran's Memorial Building, 941 Walnut Avenue.
The 101 Freeway was shut down in both directions - northbound at State Route 33 and southbound at Bates Road. Ojai residents were advised to use caution while traveling or cycling near Highway 150 between Oak View and Carpinteria due to heavy traffic caused by the closures.
Those driving in the area were asked to use Highway 150 as an alternative route.
