What the storms have been like on SF’s most remoted islands

On a transparent day, you’ll be able to stand on Ocean Seaside and see the jagged define of San Francisco’s westernmost level peeking out over the horizon.

There hadn’t been clear days in fairly a while as California was ravaged by a parade of storms from late December 2022 into mid-January, and 28 miles west of the Golden Gate, a handful of scientists on the Farallon Islands had a front- row seat to the climate occasion’s full ferocity.

“It was nearly like getting ready for a hurricane,” stated Pete Warzybok, a senior marine ecologist and Farallon Program chief on the Level Blue Conservation Science analysis institute.

All year long, a rotating crew of 4 to eight Level Blue researchers lives on Southeast Farallon Island, one of many 4 rocky outcroppings that make up the Farallon Islands Nationwide Wildlife Refuge. Though the islands are a part of the town and county of San Francisco, these scientists are the one individuals allowed to step foot there.

Claire Nasr, the Farallon Program’s lead winter biologist, is presently finishing a season on the islands with Warzybok and an all-female staff of 4 analysis assistants. She stated the Farallons’ winter crews often see some tough climate, however this season’s storms have been particularly brutal.

“These form of storms do not occur on a regular basis. I believe these occasions are actually outstanding, and we get to seize them, being out right here,” Nasr stated.

Waves crash throughout the latest California storms on the north shore of the Farallon Islands Nationwide Wildlife Refuge close to Sea Lion Cove, the place roughly 5,000 California sea lions haul out to relaxation.

Nasr’s and Warzybok’s descriptions of the storms sound just like these of Californians residing on the north and central coasts—30-foot waves, excessive winds and highly effective ocean swells. However on a craggy 95-acre island miles away from civilization, occasions like this may be particularly unnerving. The staff took additional precautions to arrange, together with anchoring down something that may very well be blown away by the wind and utilizing a crane to safe their Zodiac boat, which is used to shuttle meals and provides again to the island from bigger boats that carry deliveries from the mainland each two weeks.

“That was one thing that took fairly a little bit of time and planning to ensure it was secure,” Nasr stated, “and it definitely was.”

The Zodiac boat was pushed a few meter by the waves, however nothing was broken. Surprisingly, in addition to a couple of free shingles and a few minor flooding, the picket homes that the researchers reside in—constructed within the 1870s—have been additionally left unscathed.

A Cypress tree near researcher housing on Southeast Farallon Island was split in half due to heavy wind and rain during the recent storms.

“Despite the fact that it was depressing outdoors, me and our crew spent a very very long time outdoors simply observing the largest waves we have seen, I believe in our lives,” Nasr stated.



The main target of the islands’ winter researchers is pinnipeds, the scientific identify for seals and sea lions. Nasr stated that throughout the storms, a number of of the roughly 5,000 California sea lions that reside close by throughout the wintertime have been “hauled out” onto elements of the island they sometimes do not use, together with plenty of elephant seals.

“They have been hauled out nearly proper at our entrance porch. Oftentimes they will hand around in the intertidal, which is the place all the ocean stars and mussels are, however this time they have been hauled out within the mud proper by our home, which was neat,” Nasr stated.

An elephant seal colony on the Farallon Islands was inundated with large waves on Jan. 5.

Nasr and Warzybok famous that one impression of the storms was small-scale topographical adjustments to the rocky coves and gulches across the island’s shores. The motion and erosion of rocks and boulders imply that the Farallons’ shorelines now look barely totally different.

“The drive of waves, once they get that giant, is admittedly unbelievable and continually reshaping the shoreline on the island,” Warzybok stated. “If you’re out right here for a storm like that, you may stroll round a couple of days afterward and see rockslides and boulders transferring and logs washing up which have been floating across the ocean. It is enjoyable to see these adjustments.”

The storm did carry a couple of optimistic impacts to the islands as nicely, one being the gathering of tens of 1000’s of gallons of rainwater, which will probably be utilized by researchers there all year long. The Farallons’ usable water provide consists completely of rainwater, Warzybok stated.

Heavy rains additionally gave the scientists a small respite from the mice infestation that is been affecting the islands for a number of years.

“I’d wager the variety of mice that survived the storm is way lower than what was right here earlier than,” Warzybok stated. “They dig burrows on the marine terrace, and lots of of these would have been flooded out throughout the storms.”

General, the Farallon Islands’ few inhabitants fared nicely throughout this winter’s excessive climate.

“To be on the entrance line throughout storms like it is a distinctive and particular alternative for us as biologists, who spend our lives observing nature,” Warzybok stated. “The possibility to see nature in its full fury may be very thrilling.”
