July 4th forecast: Will you need sunglasses or a raincoat?
A record 72.2 million Americans are expected to travel during the days leading up to the July 4th weekend, with 62.2 million to travel by car, the American Automobile Association (AAA) stated in a press release. For some, it' i's a day trip. For others, it is a long weekend or an entire week of travel from the last weekend in June through the first weekend of July, visiting friends, relatives or spending time at the beach or the mountains.
In the several days leading up to the Fourth of July, expect very warm to hot conditions in much of the West, typical summer warmth from the Great Lakes to the Northeast and humid conditions with showers and thunderstorms from New Mexico to the Carolinas, Georgia and Florida.
"Portions of the Midwest, Southeast and interior Southwest stand the most likely chance for some disruptive downpours and potent thunderstorm activity on Friday, July 4," AccuWeather's Lead Long-Range Meteorologist Paul Pastelok said.
An area of clouds, showers and thunderstorms is forecast to evolve from the northeastern Gulf coast to the southern Atlantic coast later in June and linger through the first part of July. It is possible this broad area of low pressure could organize into one or more tropical rainstorms during this time.
Those heading to the beaches from northern Florida and the Alabama and Mississippi panhandles to the coastal Carolinas may experience rough surf conditions and perhaps stiff winds should a tropical depression or storm try to develop.
Around the July 4th holiday, in areas farther to the northwest, "we expect one or more complexes of thunderstorms to develop over the northern and central Plains and wander into the Midwest," Pastelok said. "Exactly where these storms wander will determine which areas could receive heavy rain and severe weather." Outside of the thunderstorms, the weather may be just fine for outdoor plans most of the day on Friday.
Thunderstorms will be possible for at least part of the day in Minneapolis, Chicago, Indianapolis, St. Louis and Kansas City, Missouri. It is possible that clouds and downpours could affect outdoor activities in some of these major metro areas and others in the region.
Conditions in much of the Northeast will be far cooler than during this week's heat wave. In fact, it could be very comfortable, provided high pressure settles slowly over the region rather than slipping off the Atlantic coast. Humidity levels are likely to be lower than July standards, far lower in most areas compared to the swelter of late.
Some showers are likely to skirt northern New England and upstate New York, but the day and evening of July 4 are likely to be free of rain in the zone from Boston to New York City and Washington, D.C., which should be good news for some of the largest fireworks displays in the nation. Folks heading to Coney Island, New York, will probably need sunglasses.
Another active zone for thunderstorms is likely to be New Mexico, western Texas, part of Colorado and eastern Arizona as the North American monsoon continues to unfold. Most of the thunderstorm activity on Independence Day will tend to occur from mid-afternoon to mid-evening, but there can be some exceptions. Aside from the threat of lightning strikes for those caught outdoors as storms build during the midday hours, flash flooding will remain a concern.
Elsewhere, showers will dampen western Washington and northwestern Oregon. While it will rain for only a small part of July 4, it could shower in the morning just as well as in the afternoon or evening.Have the app? Unlock AccuWeather Alerts™ with Premium+
"If it's heat you want, the best bets with sunglasses needed, will be the interior West, portions of the Plains and the interior Southeast on Independence Day," Pastelok explained. Highs will be well into the 90s to the low 100s over the deserts of the Southwest, while highs mainly in the upper 80s to the mid-90s are forecast for much of the Plains and interior Southeast, away from the stormy coastal areas.
In general, the West will be best overall for the Fourth of July, with only a few pockets where rain is likely to fall. However, folks are reminded to check with local laws and restrictions before setting off any backyard fireworks. Local dry conditions may prevent fireworks altogether.
For those heading to the beach, the Fourth of July often brings some chilly surf, especially in New England, the upper mid-Atlantic and much of the Pacific Coast.
Surf temperatures typically range from the upper 40s to the low 60s in New England and along much of the Pacific coast.
Waters are generally warm enough and safe for swimming along the Gulf and southern Atlantic coasts, with widespread surf temperatures in the 80s.

Stars, Stripes, And Sustainability: A Smarter Fourth Of July
Celebrating 4th Of July The Fourth of July is a time to gather, grill, spend with people that you care about and celebrating freedom, community, and the joy of summer. It is also a great opportunity to reflect on what it means to honor the country and take better care of it. This year, more Americans are choosing to celebrate consciously by finding easy and joyful ways to reduce waste, travel smarter, and lighten their footprint, without losing the spark of the season of course. Every Fourth of July, the skies glow with fireworks, grills sizzle with burgers, and highways fill with millions of travelers eager to enjoy America's Independence Day. Alongside the celebration comes an environmental cost of excess waste, emissions, and air and water pollution. Waste generation spikes significantly during summer holidays, with single-use plastics, food waste, and packaging leading the charge. The good thing is that with intentional choices, Americans can honor the land of the free without compromising the planet. Amidst a breathtaking sunset, an airplane lands gracefully. One of the most significant yet overlooked contributors to the holiday's environmental toll is travel. Domestic air travel typically surges during the Fourth of July weekend, and according to the International Air Transport Association, air travel is projected to be 5.8% in 2025 a reduction from from 10.6% in 2024. Cool Effect is a nonprofit platform that allows individuals and businesses to fund vetted carbon reduction activities, helping to offset unavoidable emissions. 'Air travel is a hard-to-abate sector,' explains Jodi Manning, CEO of Cool Effect, in an exclusive interview. 'While Sustainable Aviation Fuel production is increasing, it's not enough to meet the climate challenge. That's why travelers are taking matters into their own hands.' For example, between May and August 2024, Cool Effect saw an 81% year-over-year increase in individuals and businesses purchasing high-quality carbon offsets for their travel. 'It's a clear signal that travelers are more climate-conscious than ever,' Manning notes. 'Offsetting isn't a silver bullet, but it's a powerful and immediate way for people to take responsibility for the emissions tied to necessary travel.' Manning offered several actionable tips to fly sustainably this season: How to Celebrate Fourth of July Sustainably at Home This Fourth of July While a lot of the conversation around Independence Day and sustainability focuses on travel, the environmental footprint at home is just as critical. These range from from disposable tableware and uneaten food to plastic décor and fireworks. The following highlight the other ways to celebrate Independence Day sustainably. Over 561 billion disposable food service items are used annually in the U.S., according to the Plastic Pollution Coalition. Swapping plastic plates, cups, and cutlery for reusable or certified compostable alternatives, such as those made from bamboo or bagasse can significantly reduce landfill waste. The Natural Resources Defense Council estimates that up to 40% of food in the U.S. is wasted. Serving smaller portions, planning menus carefully, freezing leftovers, and composting food scraps can significantly reduce waste. Sharing surplus meals through community apps like Too Good To Go helps to address food insecurity while diverting food from landfills. Sourcing locally is another high-impact action and buying from farmers' markets can help to reduce transport-related emissions and supports your local economy. Seasonal options like corn, tomatoes, cucumbers, and berries are in peak abundance and ideal for July gatherings. Traditional fireworks have long been a staple of Independence Day celebrations, but their environmental and health toll is increasingly hard to ignore. In 2022, Americans set off an estimated 460 million pounds of fireworks, according to BBC, nearly one and a half pounds per person. These displays contribute significantly to airborne particulate matter, releasing metal particles, sulfur-coal compounds, and smoke that can degrade air quality and pose respiratory risks, particularly for children and those with asthma. Cities like Aspen and Salt Lake City are now embracing drone and laser shows which are cleaner, quieter alternatives that reduce fire hazards, eliminate chemical debris, and offer a modern, visually striking replacement to traditional fireworks Single-use decorations add to plastic waste that often ends up in oceans and landfills. Instead, opt for long-lasting décor, upcycling and replacing disposable party supplies with reusables can reduce event-related waste by over 70%. A multi-generation family celebrating Independence Day As you celebrate this Independence Day, let it be a moment of reflection on the freedom and the responsibility that comes with it. From smarter travel choices to thoughtful meals, reusable goods, and cleaner skies, each action you take has the power to protect the environment. Sustainability does not mean dialing down the joy. It means leveling up the meaning behind it, less waste, mindful choices and lower emissions. This Fourth of July, celebrate boldly, celebrate joyfully, and celebrate consciously.

Bay Area's final June weekend brings milder coastal weather and inland heat
As June's final weekend approaches, the Bay Area is set for a weather pattern that's becoming all too familiar: a sharp contrast between a cool, compressed marine layer along the coast and a gentle warmup inland. Unlike last weekend's blustery conditions, wind won't be a factor this time. However, the Peninsula and areas near the water will continue to experience cooler temperatures. San Francisco might finally hit the elusive 70-degree mark for the first time this month on Friday or Saturday. But don't get too excited as temperatures are expected to plateau on Saturday and even dip slightly on Sunday, as a weak upper-level low drifts in from the Pacific. This incoming system won't cause any significant disruptions in the Bay Area, just slightly cooler temperatures on Sunday and Monday, along with a reinforced marine layer hugging the coast. It's a continuation of a persistent theme in June; frequent upper-level storm systems nudging their way down the West Coast, keeping much of coastal California cool and cloudy. The result? One of the coolest Junes in decades for the Bay Area. This chilly trend extends through Central California, with several locations like Monterey and Napa tracking for their fifth coolest June on record, based on average maximum temperatures. Even the Central Valley, while not as cool, has bucked its usual trend of extreme heat in June. Sacramento, for instance, hasn't hit 100 degrees this month. If that holds through the month's end, it'll be the first June in nearly 20 years without at least one triple-digit day. So what's in store as we approach the Fourth of July holiday week? The Climate Prediction Center's 6- to 10-day outlook suggests a return to warmer conditions. However, the devil's in the details. Some weather models hint at yet another upper-level low lingering off the California coast, which could keep cooler conditions in place as we flip the calendar from June to July. Weekend breakdown San Francisco: The city will see a stretch of seasonably mild, mostly cooperative weather heading into the weekend. Friday and Saturday start with patchy clouds, especially on the west side, but sunshine breaks out by midmorning both days. Expect highs near 70 degrees downtown and in the Mission, with low 60s west of Twin Peaks. Southwest winds pick up to 10 to 20 mph each afternoon. Sunday brings a slightly thicker marine layer. Low clouds may linger longer, especially in the Outer Sunset and Richmond, keeping highs in the low to mid-60s across the city. Eastern neighborhoods will still catch some sun by early afternoon, just not as much as Friday or Saturday. North Bay: The region will run hot and sunny to close out the week, with Santa Rosa pushing into the low 90s on Friday and Saturday. Most other spots like Napa, Petaluma, Novato and San Rafael will be in the mid- to upper 80s under clear skies and barely a breeze. Sunday brings a touch more morning cloud cover and a subtle cooldown, but not enough to change plans. Expect highs in the upper 70s to mid-80s across the valleys, with Santa Rosa and inland Napa still flirting with the upper 80s by late afternoon. East Bay: A warm and sunny stretch is ahead, with Friday and Saturday both delivering some of the nicest weather in some time. Temperatures will be in the mid- to upper 70s in Berkeley, Oakland and Richmond, the low 80s in Hayward and Fremont and low 90s across the Tri-Valley in Walnut Creek, Concord and Livermore. Sunday may bring a touch more marine influence near the bay, but inland spots will still heat up. Highs will be in the low to mid-70s along the water, with upper 80s to near 90 once you get east of the hills. Pacific Coast and Peninsula: Clouds will hug the Pacific Coast each morning, but Friday and Saturday will still manage a decent dose of sunshine across the Peninsula. Coastal spots like Daly City and Pacifica will warm into the mid- to upper 60s, while across the Peninsula South San Francisco and San Mateo will see temperatures in the low 70s. Sunday brings a thicker marine layer and slightly cooler temperatures. Highs along the coast will settle back into the low to mid-60s, with inland Peninsula spots running a few degrees cooler than the previous days, generally upper 60s to low 70s. South Bay and Santa Cruz: The region will be sunny and warm all weekend, with morning clouds near the coast. Friday and Saturday bring mid-80s to San Jose, Santa Clara and Cupertino, while Santa Cruz stays cooler but pleasant in the mid-70s. Sunshine should break out early inland, with slower clearing along the coast. Sunday will trend just a touch cooler, with low 80s inland and low 70s near the water, but skies stay mostly sunny.

National Hurricane Center monitors multiple systems ahead of possible tropical increase
A tropical disturbance in the northwestern Caribbean popped up Thursday night and is showing a low chance for development over the next few days. Elsewhere in the tropics, the National Hurricane Center is keeping an eye on four tropical waves, including two in the Caribbean. ➤ Track all active storms ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location There's been only one named storm in the Atlantic basin so far this season but forecasters are keeping an eye on areas close to the U.S. showing some potential for development as we get close to the Fourth of July weekend. The next named storm of the Atlantic hurricane season will be Barry. Keep an umbrella handy today. Showers and thunderstorms are predicted across most of Florida Friday, June 27, according to the National Weather Service. Here's the latest advisory from the National Hurricane Center as of 2 p.m., June 27. A broad area of low pressure has formed over the Yucatan Peninsula in association with a large area of disorganized showers and thunderstorms over the northwestern Caribbean Sea and the Yucatan Peninsula. Some additional development is possible over the next few days when the system moves into the Bay of Campeche this weekend. By early next week this system should move inland over Mexico, ending its chances of additional development. Regardless of development, locally heavy rains are possible over portions of Belize, Guatemala, and southeastern Mexico during the next few days. Formation chance through 48 hours: 20 percent. Formation chance through seven days: 30 percent. Tropical waves Tropical wave 1: An eastern Atlantic tropical wave is near 35W from 15N southward, and moving west around 11 mph. Tropical wave 2: A central Atlantic tropical wave is near 52W from 17N southward, and moving west around 11 mph. Tropical wave 3: A western Caribbean tropical wave is near 83W from 16N southward across western Panama into the East Pacific. It is moving west at 11 mph. Tropical wave 4: Another tropical wave is along 90W from the northern Yucatan Peninsula southward across Guatemala and El Salvador into the East Pacific. It is moving west at around 6 mph. The hatched areas on the National Hurricane Center's tropical outlook map indicate "areas where a tropical cyclone — which could be a tropical depression, tropical storm or hurricane — could develop," said National Hurricane Center Deputy Director Jamie Rhome. The colors make it visibly clear how likely a system could develop, with yellow being low, orange medium, and red high. The National Hurricane Center generally doesn't issue tropical advisories until there is a named storm, but there is an exception. "If a system is near land and there is potential for development, the National Hurricane Center won't wait before it issues advisories, even if the system hasn't become an actual storm. This gives residents time to prepare," Rhome said. There's no tropical system threatening Florida at this time. However, AccuWeather forecasters are warning there is a potential for tropical development in the Gulf or off the southeast coast of the U.S. in early July, the holiday weekend. 'The potential is definitely there off the Southeast Coast or in the Gulf," said Alex DaSilva, AccuWeather lead hurricane expert via email. "The water temperatures are warm enough to support tropical development in that area and the wind shear looks to be fairly low overall in that area.' 'We're forecasting a low chance that anything develops at this point, but this time of the year, this is where we would typically see tropical activity spin up in late June and early July, If anything develops over the next two weeks, it will happen close to home. "There's nothing unusual here. We would typically look close to home for possible tropical development early in the season. If anything develops, it's likely that rainfall would be the primary concern. 'A cold front during the first couple of days of July will come off the southeast coast and stall. The tail of the front will essentially extend across Florida and into the Gulf. If that frontal boundary stalls for a couple of days and we see any convection, that's how we could end up with tropical development next week." 'We expect tropical activity to pick up later on in the hurricane season. This very well could be a back-half loaded season," DaSilva said. Right now, dry air and wind shear are helping keep tropical storms from developing, which isn't unusual for early in the hurricane season, which started June 1. "The second named storm in the Atlantic basin typically doesn't develop until mid to late July. We are on pace with the historical average. Records show that the first hurricane of the season typically doesn't develop until Aug. 11," DaSilva said. Predictions issued by NOAA, AccuWeather and Colorado State University all forecast an above-normal hurricane season. "We're forecasting a wet pattern across the Southeast in early July, regardless of any tropical development," DaSilva said. 'Much of Florida and the Southeast will see plenty of showers and thunderstorms during early July, and that could impact outdoor plans for the Fourth of July. 'Northern Florida and the Panhandle will see more rainfall than South Florida in early July.' 'There is a big plume of dust coming across the Atlantic right now. We expect more Saharan dust to reach portions of the southern U.S. from South Florida to Texas. 'We could have some Saharan dust high in the sky for the Fourth of July, especially across South Florida.' 'We could see some dirty rain across Florida that can make a mess on your car and other surfaces outside, thanks to the Saharan dust.' Florida weather forecast for June 27, 2025 Pensacola, western Panhandle: Early start to the morning with showers and storms already firing up along the coastline and out over the Gulf this morning. High near 87. Tallahassee, central Panhandle: Showers and thunderstorms likely today, with high near 92. Jacksonville, North/Northeast Florida: Thunderstorm chances Increasing this afternoon and few severe storms are possible. Expect storms to develop along the sea breezes and northward from central Florida during the afternoon hours. The main threat with storms will be strong wind gusts. High near 91. Daytona Beach to Stuart, East/Central Florida: Plenty of thunderstorms expected this afternoon-evening from increasing moisture and a sea breeze collision near the Orlando metro area. Strong storms are possible and there is a marginal risk for severe thunderstorms across much of the state. Temperatures expected to range from 88 in Daytona Beach to 87 in Stuart. West Palm Beach to Naples, South/Southwest Florida: Quiet across South Florida this morning with the exception of a thunderstorm with plenty of lightning just offshore of Naples. Scattered storms and showers pick up in coverage this afternoon. Naples high near 90; West Palm Beach high near 84. Fort Myers to Sarasota, West/Southwest Florida: Interior portions of the forecast area are under a marginal risk for severe thunderstorms today with a threat of damaging wind gusts, hail 1inches in diameter or greater and locally heavy rainfall. Fort Myers high near 92 with heat index as high as 99; Sarasota high near 87. The Atlantic hurricane season runs from June 1 through Nov. 30. Ninety-seven percent of tropical cyclone activity occurs during this time period, NOAA said. The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of America, as the Gulf of Mexico is now known in the U.S. per an order from President Trump. NOAA and the National Hurricane Center are now using Gulf of America on its maps and in its advisories. The peak of the season is Sept. 10, with the most activity happening between mid-August and mid-October, according to the Hurricane Center. Systems currently being monitored by the National Hurricane Center include: Tropical cyclone is the generic term used by the National Weather Service, NOAA and the National Hurricane Center for any tropical system, even if it's in the tropical Atlantic basin. To be more precise, a tropical cyclone is a "rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation," NOAA sadi. Once maximum sustained winds reach 74 mph, what it is called is determined by where it originated: : for storms in the North Atlantic, central North Pacific, and eastern North Pacific. : for storms in the Northwest Pacific. : for storms in the South Pacific and Indian Ocean.
