The juvenile minke whale had been spotted swimming around San Francisco Bay for nearly a week by the time she beached herself off the coast of Emeryville on April 8. Scientists had thought she seemed healthy, but after an examination, they determined she was acting abnormally and had to be euthanized due to illness.

It was the fourth whale death in the San Francisco Bay in a week and a half. The other three were gray whales, the first of which—a 36-foot-long female—washed up at Black Sands Beach in the Marin Headlands on March 30. Its cause of death remains unknown.

On April 2, a deceased adult male gray whale was found floating east of Angel Island; its cause of death is also not known, according to the Marine Mammal Center. Then, a subadult male gray whale washed ashore at Fort Point Rock Beach near the Golden Gate Bridge in San Francisco on April 4, and scientists determined that it likely died due to a vessel strike, according to the mammal center.

Taken together, the deaths have raised the specter of past “unusual mortality events” that caused whales to die in higher-than-normal numbers.

“This is unusual,” said Kathi George, director of Cetacean Conservation Biology at the Marine Mammal Center in Sausalito. “It takes me back to several years ago when we did have a large number of strandings happen at the same time.”

While the unusually high number of whales beaching in such a short span is abnormal, the number of whales who have died around the bay for the year has remained in line with typical levels, scientists say.

“This is the normal time of year when gray whales are doing their northward migration from Mexico up to Alaska, so it’s not uncommon for us to have gray whales in and around San Francisco Bay in April and May each year,” said Moe Flannery, who leads the marine mammal necropsy team at the California Academy of Sciences.

“Although they seem high because they’re concentrated into a short period of time, the numbers of dead and stranded are not any different than the recent previous years.”

Whales can die for “a number of reasons”—from diseases to malnutrition to vessel strikes, George said.

“It’s coincidental that everything happened in a week and a half, but there are a lot of whales out there right now, and some of their physical condition that they’re in when they arrive in the bay may make them more susceptible to human impacts if they’re not as healthy,” she said.

Scientists began observing whales entering the San Francisco Bay around 2016 as they completed their annual migration between Mexico and the sub-Arctic, George said. The whales do not feed while they are in their breeding grounds in Mexico, and expend a lot of energy mating, nursing babies and giving birth before facing a long journey back north to their feeding grounds, she added.

Because of this energy expenditure, scientists have seen the gray whales attempt to feed in new locations—including San Francisco Bay, George said. Their increased appearance in the bay could also potentially be explained as whales seeking a place to rest before continuing the migration, or a reaction to climate change, warming ocean temperatures and prey availability.

The Marine Mammal Center has tracked at least 18 individual whales swimming in the bay this year, and sightings of gray whales have been reported almost every day since mid-March, George said. The majority of the whale sightings have been reported east of Angel Island, said Giancarlo Rulli, the associate director of public relations for the Marine Mammal Center.

Between 2019 and 2023, gray whales were dying in much higher numbers due to an unusual mortality event, which was declared by the National Oceanic and Atmospheric Administration Fisheries. Gray whales lost more than 40% of their population in four years, Rulli said. During this time, there were 347 gray whale strandings in the United States, according to NOAA.

“These whales basically left the Arctic with a half tank,” Rulli said. “The food sources that they were normally accustomed to eating that were highly nutritious for this massive, 10,000–12,000-mile journey, had moved farther away due to climate change, and as a result, these whales were left to forage on food matter that was much less nutritious.”

Between January and April 2019, which was the first year of the unusual mortality event, 34 dead gray whales washed up on California’s coast, Flannery said. Seven have so far this year.

George said that whether the recent deaths could be the start of an unusual mortality event is “still under discussion and review,” adding that the data collected from these strandings will help scientists understand “the bigger picture of what’s happening.”

“We’re not there yet,” she said, adding that scientists have to look at their migratory range holistically.

Whales will continue to appear in the bay through mid-May as they continue their migration north, George said.

Flannery added that anyone using the water “needs to be more aware of the animals that are sharing that environment.”

San Francisco District Attorney speaks on city’s crime drop


Thursday marks one year in office for San Francisco Mayor Daniel Lurie.

Lurie was elected in the 14th round of ranked choice voting in 2024, beating incumbent London Breed.

His campaign centered around public safety and revitalization of the city.

Mayor Lurie is also celebrating a significant drop in crime; late last week, the police chief said crime hit historic lows in 2025.

  • Overall violent crime dropped 25% in the city, which includes the lowest homicide rate since the 1950s.
  • Robberies are down 24%.
  • Car break-ins are down 43%.

San Francisco District Attorney Brooke Jenkins spoke with NBC Bay Area about this accomplishment. Watch the full interview in the video player above.

San Francisco celebrates drop in traffic deaths


San Francisco says traffic deaths plunged 42% last year.

While the city celebrates the numbers, leaders say there’s still a lot more work to do.

“We are so glad to see fewer of these tragedies on our streets last year, and I hope this is a turning point for this city,” said Marta Lindsey with Walk San Francisco.

Marta is cautiously optimistic as the city looks to build on its street safety efforts.

“The city has been doing more of the things we need on our streets, whether its speed cameras or daylighting or speed humps,” she said.

Viktorya Wise with the San Francisco Municipal Transportation Agency said there are many things the agency has been doing to ensure street safety is the focus, including adding speed cameras at 33 locations, and it’s paying off.

“Besides the visible speed cameras, we’re doing a lot of basic bread and butter work on our streets,” Wise said. “For example, we’re really data driven and focused on the high injury network.”

Late last year, Mayor Daniel Lurie announced the city’s street safety initiative.

“Bringing together all of the departments, all of the city family to collectively tackle the problem of street safety,” Wise said. “And all of us working together into the future, I’m very hopeful that we will continue this trend.”

Year 1 of the Lurie era is done. Here’s how he kept — or whiffed — his biggest promises

Year 1 of the Lurie era is done. Here’s how he kept — or whiffed — his biggest promises


On Jan. 8 of last year, San Francisco tried on its new mayor like a pair of Levi’s 501 jeans. 

So far, it has liked the fit.

For 365 days, Mayor Daniel Lurie has taken swings at solving the city’s ills: scrambling to scrap the fentanyl scourge, working to house the homeless, and shaking his proverbial pompoms with enough vigor to cheerlead downtown back to life. 

So is San Francisco all fixed now?

The eye test tells one story. The data tell another. But politics is more than paper gains and policy battles. It’s also a popularity contest — and Lurie has categorically been winning his, riding high on a stratospheric 71% approval rating.

Lurie’s rainbow-filled Instagram posts have gone a long way toward soothing locals’ doom-loop fears, but the political fortress he’s built over the past year could easily crumble.

After all, his predecessors as mayor, London Breed and the late Ed Lee, each enjoyed positive approval ratings (opens in new tab) in their first year in office. But the honeymoons lasted only about that long before voters gradually soured on their performance. Should San Franciscans’ adulation for Lurie similarly ebb, his policies might meet more resistance.

Still, if there’s one pattern with Lurie’s efforts in his freshman year, it’s this: While he hasn’t achieved all of his lofty goals, he has fundamentally changed how the city approaches many of its problems, potentially setting up success for future years.

As we enter Lurie: Year 2, here’s a rundown of where the mayor has delivered on his campaign promises, where he’s been stymied, and why voters may continue to give him the benefit of the doubt. At least, for now.

Misery on the streets

Headwinds: While Candidate Lurie promised to declare a fentanyl “state of emergency” on his first day in office, he quickly found it wasn’t legal to do so. (Per the city’s administrative codes, an emergency needs to be sudden and unforeseen; the fentanyl epidemic was neither.) Instead, the mayor asked the Board of Supervisors to grant him similar powers that an emergency declaration would have afforded him, and they agreed. But as Lurie touted his efforts to curb drug use on Sixth Street, all those drug dealers just moseyed on down to the Mission. The mayor’s first year in office ended with 588 drug overdose deaths, according to the office of the medical examiner (opens in new tab). That’s an improvement from the 635 in 2024, but it’s still an appalling body count — and December 2025 isn’t even part of the official tally yet. 

Silver linings: The mayor employed his newfound powers to speed up approvals of initiatives, notching well-publicized wins, like fast-tracking the 822 Geary stabilization center, where police can place mentally ill folks instead of arresting them. It’s got a 25% better success rate at connecting patients to treatment than previous facilities, according to city data, part of a noted change for the better in the Tenderloin. And while some of the police’s high-profile drug busts didn’t net, you know, actual drug dealers, law-and-order-hungry San Franciscans were just happy to see batons fly.

Shelter-bed shuffle

Headwinds: On the campaign trail, Lurie talked a big game about his nonprofit experience, which he claimed had allowed him to cinch deals to create shelter that seasoned politicians had been too slow to enact. He even promised 1,500 treatment and recovery beds built for homeless folks in just six months. By midyear, he had backed off that promise. The real number of beds Lurie created in 2025 is about 500, and that’s after 12 months — twice the amount of time he gave himself. 

Silver linings: Housed San Franciscans gauge success on homelessness with their eyeballs, not bureaucrats’ spreadsheets. By that measure, Lurie is succeeding. As of December, the city counted (opens in new tab) just 162 tents and similar structures, almost half as many as the previous year. (And as a stark counter to what some would call an achievement, for people on the streets, that can mean danger — without a thin layer of nylon to hide in, homeless women say they are experiencing more sexual assaults.) And drug markets haven’t vanished; they just moved to later hours. But are folks really getting help? Rudy Bakta, a man living on San Francisco’s streets, would tell you no, as he’s stuck in systemic limbo seeking a home. He’s just one of thousands.

Reviving the economy

Headwinds: Lurie asked for (opens in new tab) “18 to 24 months” to see downtown booming again, so we shouldn’t ding him for Market Street’s continued slow recovery. Foot traffic downtown has generally risen, reaching 80% of pre-pandemic levels by midyear, but slumped to roughly 70% as of November. While it doesn’t sound like much, that’s a reversal of the rising trend the city controller had projected. Office attendance is also slipping. It had risen past 45% of pre-pandemic occupancy in January 2025 but by the fall had slid below 40%. 

Other economic indicators are wobbly too. Hotel occupancy “lost steam” in November, the controller wrote, nearing pre-pandemic levels in the summer but dipping below 2019 levels in the fall. The poster child for downtown’s troubles is undoubtedly the San Francisco Centre, the cavernous, and soon tenantless, shell of its former self. And while public employee unions are undoubtedly happy that promised layoffs were avoided, Lurie’s light hand in his first-ever budget pushed some even harder decisions to 2026’s budget season. 

Silver linings: There’s a brighter story to tell outside the Financial District: Neighborhoods are where the action is nowadays. Just ask anyone dining at one of Stonestown Galleria’s 27 restaurants. This is where Lurie’s Instagram account (opens in new tab) truly has generated its own reality, crafting an image of a retail and restaurant renaissance. While that neighborhood vibrancy may lead some to shrug their shoulders concerning downtown’s continuing malaise, it’s worth noting that San Francisco’s coffers depend on taxes generated by the businesses nestled in those skyscrapers. There’s a reason we had a nearly $800 million budget deficit last year.

Fully staffing the SFPD

Source: Jason Henry for The Standard

Headwinds: At first glance, Lurie appears on track to meet his campaign promise to staff up the city’s police force. “I’ve talked with current command staff and former command staff. We can recruit 425 officers in my first three years. We will get that done,” he said at a 2024 League of Women Voters forum. True to his word, the SFPD hired and rehired roughly 144 officers last year. There’s just one problem: The department recalculated the number of officers it needs in order to be fully staffed, raising the number to 691. And the police academy, which already struggled with graduating officers, might be hampered in the aftermath of a cadet’s death, after which top brass reassigned the academy’s leadership. 

Silver linings: Crime is trending down, and that’s what voters care about, full stop. The reduction is part of a national trend (opens in new tab), yes, but San Francisco’s rates are experiencing an exceptional drop. Really, Lurie really should be sending Breed a thank-you card. Her March 2024 ballot measure Proposition E (opens in new tab) gave the SFPD carte blanche to unleash a bevy of technological tools to enable arrests, including drones and license plate readers, which have seen noted success. “Soon as you slide past that motherf—er with stolen plates, they’re gonna issue a warning to every SFPD station in that area, if not the entire city … and they start dispatching to that area,” rapper Dreamlife Rizzy said in a recent podcast, as reported by the New York Post (opens in new tab). That is music to any crime-fighting mayor’s ears.
