When is daylight saving time? Here's when to 'fall back' in 2025
Although the movement to get rid of the clock change has grown in recent years, daylight saving time is still happening across most of the U.S., as the twice-a-year movement of clocks either backward or forward accounts for more daylight in the mornings or evenings for millions of Americans.
In November, when daylight saving time ends for 2025, clocks will "fall back," meaning those affected will gain an extra hour of sleep, but for some regions of the country, the time change will also mean an earlier sunset and more hours in the dark of night.
Here is what you need to know about this year's time change.
What is daylight saving time?
Daylight saving time is the time between March and November when most Americans adjust their clocks ahead by one hour.
We gain an hour in November (as opposed to losing an hour in the spring) to make for more daylight in the winter mornings. When we "spring forward" in March, it's to add more daylight in the evenings. And in the autumn, we "fall back."
When does daylight saving time end in 2025?
Daylight saving time will end for the year at 2 a.m. local time on Sunday, Nov. 2.
Next year, it will begin again on Sunday, March 8, 2025.
Does every state observe daylight saving time?
Not all states and U.S. territories participate in daylight saving time.
Hawaii and most of Arizona do not observe daylight saving time. Because of its desert climate, Arizona doesn't follow daylight saving time (with the exception of the Navajo Nation). After most of the U.S. adopted the Uniform Time Act, the state figured that there wasn't a good reason to adjust clocks to make sunset occur an hour later during the hottest months of the year.
There are also five other U.S. territories that do not participate:
The Navajo Nation, located in parts of Arizona, Utah and New Mexico, does follow daylight saving time.
Hawaii is the other state that does not observe daylight saving time. Because of its proximity to the equator, there is not a lot of variance between hours of daylight during the year.

Why burgers cost so much right now
There's no question that steak and hamburgers contribute to global warming, driven by cows' potent methane burps and their wide-ranging grazing habits. But a warming planet with intensifying extreme weather is also affecting the price of your steak and hamburgers. After years of drought, pastures haven't been producing enough grass to feed cattle. So ranchers have been sending their animals to the slaughterhouse earlier, cutting back herds even as Americans eat more beef. This is sending prices to record highs. Average ground beef prices in city supermarkets surpassed $6 a pound in June, while the cost of uncooked beef steaks approached $11.50 a pound. Those levels are the highest in a decade, according to U.S. Bureau of Labor Statistics data. The upward march of prices illustrates a phenomenon known as climate inflation, in which droughts, heat waves, floods and wildfires raise prices for everything from home insurance to groceries. While some price hikes are so far proving temporary, others are longer-lasting, like beef, which is expected to stay expensive for at least the next few years. 'This is one indicator of how climate change will affect our food system, and it's playing itself out in beef right now,' says Ben Lilliston, director of rural strategies and climate change at the Institute for Agriculture and Trade Policy, a Minneapolis-based nonprofit. 'You're seeing it in other commodities, like coffee.' U.S. beef prices are spiking after years of drought in areas where cattle are raised. In the southwestern U.S. in particular, which includes cattle-producing areas like California's San Joaquin Valley, drought has exceeded historical expectations over the last quarter-century, says Brad Rippey, a USDA meteorologist. Scientists have found that global warming's higher temperatures make droughts more likely to happen in some places and more severe. For example, a 2020 study that examined anomalously dry conditions in the western U.S. and northern Mexico between 2000 and 2018 determined that climate change contributed to nearly half of that drought's severity. Drought conditions in the U.S. in recent years were also enhanced by several instances of the naturally-occurring La Niña climate pattern, which tends to leave portions of the U.S. drier than usual, Rippey says. Ranchers have some options, including feeding their herds alternatives to pasture grass, such as hay. But as dry conditions continue, selling the cattle begins to make more financial sense than buying the expensive feed. U.S. herds have been dwindling for years and are now smaller than ever even as drought conditions have improved. 'The long-term impact is that you have less ability to produce, which is where we find ourselves now after four or five years of this process,' says Derrell Peel, agribusiness professor at Oklahoma State University. Demand from consumers for beef, meanwhile, has grown, which also contributes to higher prices. That generates a trade-off between cashing in on today's high prices and holding animals back for breeding — a process that takes years to pay off. A female calf born this year could be sold, entering next year's beef supply, or it could be bred in 2026 and rear a calf ready for market by roughly 2028. Cattle usually have only one calf at a time, in contrast with other animals like chickens and pigs. Other factors affecting cattle ranching besides drought include higher interest rates and greater costs for inputs ranging from the cattle themselves to feed and equipment. Most cattle spend their lives outdoors, exposing the animals to other hallmarks of climate change like extreme heat. High temperatures can affect cattle's reproductive health and their growth, extending the time and cost of raising animals. In the highest-emissions scenario, it could get so hot by 2050 that fewer parts of the world will be suitable for cattle production, according to the most recent Intergovernmental Panel on Climate Change report. Another climate change-related threat is also looming: a deadly parasite known as the screwworm, which was long-ago eradicated in the U.S. but has made a resurgence in Mexico. It thrives in warmer climates, and scientists say that climate change could facilitate the fly's spread. While the majority of American beef is produced domestically, the U.S. routinely imports young cattle from Mexico to fatten up in American feedlots, says David Anderson, a professor and livestock economist at Texas A&M University. The supply of those cattle, the equivalent of about 4% of U.S. calf production, has been intermittently cut off since November because of the threat the screwworm poses. 'On the margin, that's a bunch of animals,' he says. 'That's contributing to high prices.' Court writes for Bloomberg.

Tropical Storm Ivo could become hurricane Aug. 8: See path tracker, forecast
Forecasters expect Pacific storm Ivo to "start moving away from the coast of Mexico over the next day or so." As the Atlantic hurricane season enters its most significant months, forecasters are also watching two tropical storms form in the Pacific. Located about 385 miles southeast of the southern tip of Baja California, Mexico, Tropical Storm Ivo was moving northwest at 21 mph with maximum sustained winds near 60 mph and higher gusts, the National Hurricane Center said in an advisory on Thursday, Aug. 7. The center said it expects Ivo to "start moving away from the coast of Mexico over the next day or so." By the weekend, forecasters expect the storm to turn more westward, away from Mexico. Ivo will likely bring rainfall of 2 to 4 inches with some isolated totals of 6 inches across parts of the Mexican states of Guerrero, Michoacan de Ocampo and Colima through Friday, NHC forecasters said. The system may also produce swells likely to cause life-threatening surf and rip current conditions over the next few days. Tropical Storm Henriette, located about 1,195 miles east of Hilo, Hawaii, was moving west with maximum sustained winds near 45 mph with higher gusts, the center reported. NHC forecasters expect the storm to keep heading west through Thursday, Aug. 7 before turning northwest on Friday and over the weekend. The center of the storm is expected to stay well to the north of the Hawaiian Islands. No coastal watches or warnings regarding Henriette are in effect Thursday, Aug. 7 with little change in strength expected through the next few days. Pacific Ocean storm tracker Dexter expected to strengthen in the Atlantic In the north Atlantic Ocean, post-tropical cyclone Dexter was still producing tropical storm-force winds while it was located about 390 miles south-southeast of Cape Race, Newfoundland, Canada, according to the NHC. The storm had maximum sustained winds near 60 mph with higher gusts, as of Thursday afternoon, Aug. 7. The storm is expected to strengthen later Thursday through Friday, Aug. 8 before weakening Friday night into Saturday, Aug. 9. There are no threats to land stemming from the storm.

Feds take steps to fill vacancies at the National Weather Service
Weather Service will hire 450 people, but experts say it won't help fill critical vacancies during current hurricane and wildfire season. The National Weather Service has taken steps to begin filling some of the more than 550 positions left vacant by federal cutbacks and early retirements since Inauguration Day. Earlier in the summer, the agency received an emergency hiring exemption to fill 126 of its vacant positions and has begun to post those jobs on But in an all-hands meeting on Aug. 4, weather service employees learned the agency has since received permission to hire a total of 450 people by September 2026, said two long-time weather service veterans who retired earlier this year. The mass exodus of workers this winter and spring, as the Trump administration aimed to shrink the federal budget and bureaucracy, prompted widespread concern across the weather service staff, many members of Congress and the broader weather forecasting community. Vacancy rates were as high as 40% in some weather service offices, USA TODAY previously reported. Several weather service forecast offices began closing overnight because they could no longer staff the typical 24/7 operations and weather balloon launches to gather critical data were interrupted. While the new hires are "good news," it doesn't mean clear sailing for the beleaguered agency in the months ahead, given the complicated federal hiring process and the need to train new employees, said Brian LaMarre, who retired earlier this year as meteorologist-in-charge of the weather service office in Ruskin/Tampa, Florida, after more than 30 years with the agency. "That still doesn't backfill to what the agency was on January 1, but it's a good step," LaMarre said, noting it will take months to fill posts now vacant and those created by promotions. In an email to USA TODAY, the agency declined to comment, confirm or deny the information that emerged from its employee meeting Aug. 4. In that meeting, employees were told the meteorologist, hydrologist and electronics technician positions have all been exempted from an ongoing federal hiring freeze, said Alan Gerard, another 30-plus year veteran meteorologist who retired earlier this year. Gerard now writes the "Balanced Weather" blog on Substack. In July, President Donald Trump extended that freeze through Oct. 15. Mass job cuts hit NOAA, the agency that oversees hurricane center and weather service The agency also has been given direct hiring authority, a step that typically allows federal agencies slightly more flexibility with the federal hiring rules, Gerard said. Hiring new people to fill critical positions is "good news, but it's not going to help in any concrete way for many months," he said. Considering the time it takes to hire and train new people, these steps "aren't going to help for this hurricane and wildfire season." The weather service isn't just meteorologists So far, the first positions to be advertised are for electronics technician openings, which were among the 126 "critical vacancies." That's especially good news, LaMarre said. The importance of the technicians was overlooked in the initial flurry of reports about the terminations of probationary employees and the consternation over the massive departures at the weather service, he said. The technicians are responsible for maintaining and repairing the all-important radar systems and other equipment used to make forecasts, he said, not only at the weather service forecast offices but also at airports where the weather service has agreements with the Federal Aviation Administration to maintain radar equipment. "These are critical operations pieces," he said. "The publicity is often on the meteorologists, but the technicians are the foundation of what's done." LaMarre said it's also good news that hydrologists will be among those hired. It could allow the agency to follow through on a plan to place hydrologists in state emergency operations centers, to assist in forecasting flood events. They'd already done that in Virigina and were about to do it in Texas, he said.
