麻豆AV

Bordering the United States coasts of Louisiana, Mississippi, Texas, Alabama, and Florida, the Gulf of Mexico is one of the country鈥檚 best vacation destinations. As the largest gulf in the 麻豆AV, with an estimated 1,631-mile general coastline in the US, this region flaunts some of the nation鈥檚 prettiest state parks and white sand beaches.

The region is especially known for its tropical and subtropical climates which are largely regulated by the Bermuda-Azores High. This area of high-pressure air in the North Atlantic Ocean guides warm tropical air in a clockwise motion, steering it to the Gulf Coast States.

For those looking to escape the cold or simply enjoy a tropical getaway, this coastal region is your ticket to sunshine and beach days. These 11 Gulf Coast towns promise mild winters and balmy summers, perfect for enjoying their shores, piers, parks, and attractions year-round.

Naples, Florida

Averaging 264 days of sunshine a year, Naples is a quintessential Florida beach town famous for its sugar-sand shores. Summer temperatures reach the mid-90s, while winters are mild and sunny, with average high temperatures in the 70s range. With mellowed weather, some outdoor attractions even extend their hours in the winter, like Naples鈥� Corkscrew Swamp Sanctuary.

But despite this dip in temperature, this southwest Florida town is a year-round tropical paradise, with temperatures rarely dropping below 50掳F. Meaning that visitors can appreciate the 鈥淐aribbean vibe鈥� of Lowdermilk Beach, enjoy serene sunsets at Delnor-Wiggins Pass State Park, and visit the landmark Naples Pier year-round.

Marco Island, Florida

A 40-minute drive from Naples will bring you to the largest barrier island in Southwest Florida's Ten Thousand Islands chain. Boasting 6 miles of sandy shores, Marco Island is another classic beach town with some of the best year-round weather in the state. Its coolest month (January) remains incredibly comfortable, dropping to an average low of just 57掳F. January鈥檚 average high, on the other hand, reaches 73掳F, just a 1掳 difference from August鈥檚 average low of 75掳F.

With summer temperatures reaching average highs of over 90掳F, this is when shores like Tigertail Beach, South Marco Beach, and Hideaway Beach really shine. Alternatively, for a more relaxing day in the sand, travelers can rent a boat from places like The Isles of Capri Marina. A short excursion will bring you to the beautiful and secluded Keewaydin Island, located between Marco Island and Naples.

Captiva Island, Florida

In a 2024 Thrillist article, the travel website dubbed Captiva Island the top 鈥淢ust-Visit Small Town鈥� in Florida. The article highlights its easygoing downtown (鈥渓ike a much, much more laid-back version of Key West鈥�) and its gorgeous beachfront sunsets. As for the introverted traveler, Thrillest emphasizes the island鈥檚 greatest feature: its seclusion.

For beachgoers, Captiva鈥檚 subtropical climate produces hot summers and mild winters, along with an average of 266 sunny days per year. Like Naples, people visiting Captiva in the winter can expect average high temperatures in the 70s, and it is unlikely you will encounter anything below 50掳F. Many actually prefer to visit the island in winter, since summer temperatures frequently exceed 90掳F. But no matter the season, the turquoise waters and sunsets at Turner Beach and Captiva Beach are divine.

South Padre Island, Texas

Located on a barrier island of the same name, South Padre Island is another top-rated resort community. Like Captiva, this Texas island town has a subtropical climate, with long summers and gentle winters. Along with an average of 227 sunny days, visitors can expect a summer high of 91掳F and a winter low of 53掳F, making it one of the warmest places in the state.

With weather this great, shores like the South Padre Island Beach are full of life in all seasons. Other outdoor attractions are also vibrant year-round, like the South Padre Island Birding, Nature Center & Alligator Sanctuary. Listed as the #1 thing to do in South Padre Island by Tripadvisor, this beachfront center is a great activity for the whole family.

At the center, visitors can explore a birding boardwalk, an observation tower, and countless interactive animal exhibits. And unlike other sanctuaries, it is at its brightest from fall through spring due to bird migrations. Winter is also considered one of the best times to visit, with a more diverse selection of species at the center, like waterfowl, shorebirds, and songbirds.

Grand Isle, Louisiana

Over in the Bayou State, the town of Grand Isle is known for its namesake attraction, Grand Isle State Park. This beautiful barrier island attraction sees most of its visitors in the summer when the town is at its warmest, reaching 90掳F or higher. But even when this Louisiana town dips to 50掳F in the winter months, there is a low risk of seeing uncomfortable temperatures below 40掳F. Instead, winter weather ranges between 50 and 70掳F.

Located at the eastern end of Grand Isle, Grand Isle State Park is 鈥淟ouisiana鈥檚 best-known stretch of sand.鈥� With its warm Gulf waters, swimming is popular almost year-round. But even when the waves start feeling a bit too brisk, there is still plenty to see and do. Kayaking, fishing, sunset walks, and camping on the beach can be enjoyed in every season.

Panama City Beach, Florida

Back in Florida, Panama City Beach is a gateway to gorgeous shores at St. Andrews State Park. Sandwiched by the Gulf of Mexico and St. Andrews Bay, snorkeling, swimming, and surfing are in high supply in this Florida nature haven.

St. George Island, Florida

Further south, St. George Island is an unspoiled barrier island perfect for those craving a more secluded retreat. At more than 20 miles long and 1 mile wide, there is plenty of sand to go around. So if you are someone who loves uncrowded beaches for swimming, shelling, sunbathing, and wildlife viewing, this island town is for you. With annual temperatures ranging from a low of 42掳F and a high of 91掳F, visitors can expect endless fun in the sun.

Dr. Julian G. Bruce St. George Island State Park is by far the town鈥檚 most famous beach-and for good reason. Rated the #1 Beach in America by Dr. Beach, this Florida Panhandle park is simply divine for those who love undeveloped shores. With Apalachicola Bay on one side and the Gulf on the other, visitors can enjoy a nice blend of nature trails through wooded marshlands and pristine white sands. With this rich mix of nature, animal lovers on the gulf shore can keep an eye out for dolphins, while birders can appreciate the nested life out on the marshes. To explore more of the park, cyclists can also follow bike paths through 4 miles of paved trails and 3.5 miles of nature paths.

Anna Maria Island, Florida

Over 6 hours south of St. George, you will find an even warmer barrier island town. Even at its lowest average, Anna Maria Island sees temperatures of 56掳F, with an average high of just over 90掳F in August. At 7 miles long, Anna Maria may be smaller than St. George, but its beaches are equally beautiful and even more laid-back.

For those visiting Anna Maria for its location in Manatee County, November through March are the best times to spot the majestic creatures. This is when the loveable 鈥�sea cows鈥� come closer to shore in search of warmer waters. For your best chance at spotting them, head to local spots like Bean Point and Manatee Beach, or you may get lucky at the Anna Maria City Pier. But the best way to spot manatees and other marine life is by booking eco-friendly excursions with services like Florida Blue Adventures' Guided Kayak Tour.

Port Aransas, Texas

In the beautiful Texas town of Port Aransas, winter temperatures remain comfortable in the 50s and 60s, while summer stretches to a toasty mid-to-high-90s. As the "Fishing Capital of Texas," this beautiful weather means attractions like the Port Aransas Fishermans Wharf and Horace Caldwell Pier are full of life year-round.

If fishing is not really your thing, there is still plenty to see and do outdoors in Mustang Island town. Boasting 18 miles of uninterrupted public shoreline, Port Aransas Beach has a great mix of classic beach activities like swimming and sand castle building along with more adventurous experiences like soaring with Chute 鈥楨m Up Parasailing.

Surfside Beach, Texas

Surfside Beach, known by locals as 鈥淪urfside,鈥� is another scenic Texas beach town with tons of year-round sun, reaching summer temperatures in the early 90s. Since it is a bit north of Port Aransas, temperatures can drop a little bit more in the winter to low averages of 45掳F in January.
