D.C’s cherry blossoms just hit their earliest peak bloom in 20 years. Here’s why scientists say it’ll keep happening earlier.
The iconic pink and white blossoms that transform Washington, D.C. at the beginning of spring have officially hit their earliest peak bloom recorded in at least 20 years. It’s one of the earliest days it’s happened in the area on record – and experts say it will likely keep shifting earlier.
Peak bloom occurs when 70% of the Yoshino cherry blossoms planted around D.C. open up. According to the National Park Service, this usually happens between the last week of March and the first week of April. From 2004 to 2023, the annual peak mostly occurred between March 25 and April 10, with a few exceptions where it happened as early as March 20.
The service predicted on its website that peak bloom would occur this year between March 23 and March 26, but in an update on Sunday, the service’s National Mall and Memorial Parks posted an update on social media.
“PEAK BLOOM! PEAK BLOOM! PEAK BLOOM! Did we say PEAK BLOOM?!” the agency said. “The blossoms are opening & putting on a splendid spring spectacle.”
The agency confirmed peak bloom arrived on March 17 on its website on Monday. But what exactly makes them open up earlier? Scientists and National Park officials say it all has to do with the weather.
“Peak bloom varies annually depending on weather conditions,” the service says, adding that the typical bloom period also depends on weather conditions. “…Cool, calm weather can extend the length of the bloom, and a rainy, windy day can bring an abrupt end to the ephemeral blossoms. A late frost can prevent the trees from blooming at all.”
D.C.’s predicted peak blossom season is expected to come just days after scientists with the Japan Meteorological Agency said cherry blossoms have been blooming earlier over time due to rising global temperatures.
Daisuke Sasano, a climate risk management officer at the JMA’s Office of Climate Change, said in a briefing last week that overall, global temperatures have been increasing. Scientists have confirmed that 2023 was the hottest year on record and 2024 has already seen record-breaking heat.
“It is unequivocal that human influence has warmed the atmosphere, ocean and land. Climate change is already affecting every inhabited region across the globe, with human influence contributing to many observed changes in weather and climate extremes,” his presentation said, citing the United Nations’ Intergovernmental Panel on Climate Change. “Projected changes in extremes are larger in frequency and intensity with every additional increment of global warming.”
Studying a sample cherry blossom tree — called sakura in Japanese — in Tokyo, Sasano said scientists found that the average start date for cherry blossoms to bloom in Japan has gotten earlier, moving up at a rate of roughly 1.2 days every decade. That rate has a “high” correlation with the average temperature, he said. And it’s not just Tokyo — several major Japanese cities have seen earlier blooms over the past 30 years, including Osaka, Hiroshima and Sendai.
The earliest peak recorded in D.C. was March 15, 1990, according to the National Park Service, which added that this year marks the earliest peak in at least two decades. It comes as the D.C. saw above-average temperatures in both January and March. On Feb. 26, Weather Underground recorded a max temperature of 66 degrees Fahrenheit at Ronald Reagan Washington National Airport – nearly 16 degrees above average.
Global temperatures are only expected to continue to rise, furthering weather extremes – and impacting cherry blossoms. Even if greenhouse gas emissions – a primary driver of global warming – drastically decrease worldwide today, the emissions already put into the atmosphere will continue to have an impact for decades to come.
Scientists with non-profit group Climate Central have also said climate change is having an impact on blossoms. In 2018, the organization said that from 1931 to 1960, cherry blossoms in D.C. were blooming on average around April 6. From 1981 to 2010, however, the average was April 1. They also predict that in the future, blooms could happen as early as the first week of March.
Last year’s cherry blossoms stayed on trees for a little more than a week. But how long this year’s bloom remains is still a question. The National Weather Service is expecting a cold front into the Northeast U.S. at the beginning of the week that could bring some snow and wind gusts of up to 30 mph across the region, and while cool and calm can extend the life of the blossoms, rain and wind can bring their end.

Law enforcement officers were searching Friday for two inmates who escaped from a jail in southwestern Mississippi.
The two men are awaiting trial on murder charges in separate counties.
Tyrekennel Collins, 24, and Dezarrious Johnson, 18, broke out of the Claiborne County Detention Center at about 2:20 a.m. Friday, the Claiborne County Sheriff’s Department said in a social media post.
Update: Johnson has a bad limp and an injury to his right leg that occurred during the escape (Pictured on the…

The jail is in Port Gibson, about 60 miles (96.6 kilometers) southwest of Jackson.
Camera footage showed Collins and Johnson escaping through the ceiling and leaving behind an outside wall, Claiborne County Sheriff Edward Goods told WAPT-TV. Johnson injured one of his legs during the escape and was walking with a limp, the sheriff’s department said.
The Mississippi Bureau of Investigation said Collins and Johnson are considered armed and dangerous.
WJTV-TV reported Collins is charged with murder in the October killing of his cousin in Copiah County, which is about 40 miles (64.4 kilometers) west of Claiborne County. Court records on Friday did not show an indictment for Collins.
Johnson is charged with murder and aggravated assault in Jefferson County, which is just south of Claiborne County. Court records show he was indicted in the October 2022 killing of one person and injuries to two others. His trial is set to begin Oct. 15.

As sunscreen misinformation spreads online, dermatologists face real-life impact of online trends
With the holiday weekend in full swing, the anti-sunscreen movement’s recent spike is worrying dermatologists.
“It was not like this before,” Dr. Jeanine Downie, a board-certified dermatologist with her own practice in New Jersey told CBS News Confirmed. “I see easily six patients per week that are anti-sunscreen, where it used to be maybe one every other week or one a month. And now it’s just gotten crazy.”
Downie says in the last two weeks she’s diagnosed three squamous cell and two malignant melanomas, both of which can turn cancerous if not caught early. “And that’s me, just one little dermatologist,” she said.
This movement picked up steam in June, with creators on TikTok telling followers in no uncertain terms “stop wearing sunscreen.” At first, the posts received tens of thousands of views and likes. Dermatologists on the platform then began sharing their own reactions, with those videos gaining even more views. And more recently, influencer Nara Smith went viral sharing an at-home sunscreen recipe to her 8 million followers that dermatologists say does little to protect wearers from sun damage.
Dr. Shereene Idriss, a New York dermatologist who has amassed more than a million followers on her social media channels, is trying to leverage that influence to educate users about sunscreen and sun protection.
“It’s becoming more and more difficult, I think, as a consumer, to try to weed through the noise,” Idriss told CBS News Confirmed.
This misinformation reflects the surprising reality of how some young Americans view sun safety. A study by the Orlando Health Cancer Institute in March found that 1 in 7 adults under the age of 35 say daily sunscreen use is more harmful than direct sun exposure. “I tell my patients, if you want your face to look like a leather bag later, then that’s up to you,” Downie said. About 6.1 million adults are treated each year for basal cell and squamous cell carcinomas according to the CDC. Skin cancer is the most common type of cancer in the country.
“They only want the natural things,” said Downie. “But I tell them all the time, sitting in traffic here in the tri-state area, the level of pollutants in the air on a daily, weekly and monthly basis is significantly more toxic than any chemical they’re going to rub into their skin with sunblock.”
While there’s no evidence that sunscreens are unsafe, the FDA is currently investigating potential concerns. It’s called for more data on 12 ingredients often found in U.S. sunscreen. After conducting its own study into how certain ingredients are absorbed into the bloodstream, the FDA has called for more research into potential health effects on the body.
However, beachgoers on the Jersey Shore this week told CBS News that sun safety is top of mind this summer. CBS News Confirmed looked at Google Search trends and saw terms like “sunscreen” and “what does skin cancer look like” are at an all-time high since tracking began in 2004.
“You know what gets them to start wearing sunblock?” said Downie. “Young kids and young adults, Gen Z, Gen X, they hate pores. And once they hear that they’re going to have big pores that look like potholes, they put that sunblock on.”
The dermatologists CBS Newsspoke with say there is no such thing as a healthy tan. To best protect yourself this summer, they say to use sunscreen and reapply often; wear UPF clothing or UV visors; and avoid being outside during peak UV index between 10 a.m. and 2 p.m.
