Mid-May is supposed to be quiet in Southern California’s fire calendar. The Santa Ana winds don’t typically howl until fall. The chaparral hasn’t yet baked into kindling. The Sandy Fire doesn’t care.

More than 17,000 people were under mandatory evacuation orders Tuesday as a wind-driven wildfire burned through the hills above Simi Valley, roughly 30 miles northwest of Los Angeles. The blaze, reported Monday morning near the 600 block of Sandy Drive, grew from 184 acres to 1,698 acres within 24 hours. It was 5% contained as of Tuesday evening, according to CAL FIRE.

One home destroyed. No injuries reported.

In all, roughly 37,000 residents were under either evacuation orders or warnings, with the threat extending into Los Angeles County communities near Agoura Hills, Calabasas, and Hidden Hills, according to the Ventura County Star. The Simi Valley Unified School District closed all campuses. The Ronald Reagan Presidential Library shut its doors at noon Monday. A smoke advisory was issued for the city of Los Angeles due to multiple wildfires burning across the region.

‘Everything turned black’

Ron Wechsler, 82, told the Ventura County Star he tried to fight the flames with pool water before the speed of the fire forced him to flee. “Unfortunately, it was moving so fast. Everything turned black and I thought I wasn’t going to make it out of there,” he said.

Christian Mills, 22, described seeing “a giant stream of orange smoke that was starting to black out the sun.”

Gusts initially topped 30 mph, driving flames through steep, canyon-cut terrain. Firefighters made progress overnight as winds calmed, but authorities warned that Santa Ana conditions were expected to return Tuesday morning, with humidity dropping as low as 8%, according to the Ventura County Star. Some 869 personnel were assigned to the incident, CAL FIRE reported.

Ventura County Fire Department spokesperson Andrew Dowd said crews had made significant progress during the overnight lull. “We’ve made a lot of progress against this fire with those improved weather conditions,” Dowd said. The goal was to strengthen containment lines before winds picked up again.

The calendar is the story

Southern California’s most destructive wildfires tend to arrive between late summer and early winter, when months of heat have cured vegetation and the first Santa Ana wind events push down from the desert. A fire of this scale forcing mass evacuations in mid-May breaks the pattern — and raises uncomfortable questions about what the traditional peak months might bring.

If the hills are this dry and the winds this fierce five months before autumn, the window between fire seasons is barely a window at all.

Governor Gavin Newsom secured a FEMA Fire Management Assistance Grant on Monday, covering 75% of eligible suppression costs — a signal that state officials are treating this with the urgency usually reserved for late-season campaigns.

A second front offshore

Roughly 70 miles off the coast, the largest wildfire ever recorded on Santa Rosa Island had burned through nearly 15,000 acres — roughly one-quarter of the island — with zero containment as of Monday evening, the Los Angeles Times reported. The fire was inadvertently sparked by emergency flares from a shipwrecked mariner who crashed his sailboat into rocks on the island’s south side, according to the US Coast Guard.

A sportfishing boat captain later spotted the mariner standing on a sliver of unburned land surrounded by scorched earth. He’d scratched “SOS” into the blackened ground after spending a night stranded on the island.

The blaze destroyed two historic structures and crept within half a mile of one of only two natural stands of Torrey pines in existence. Roughly 70 firefighters were assigned, hampered by gale-force winds so fierce that an attempted water drop was blown away before reaching the ground. They were steering the fire along existing roads and ridges rather than cutting new lines through habitat that supports island foxes, spotted skunks, and six endemic plant species found nowhere else.

The last major fire on the Channel Islands was the 2020 Scorpion fire on Santa Cruz Island, which burned 1,368 acres. The Santa Rosa blaze has already eclipsed that ten times over.
