Are you tired of scraping ice off your windscreen and bundling up in layers just to check the mail? Winter can feel endless when you’re stuck in cold weather month after month. In this guide, we’ll explore 10 warm US spots to visit in 2025.

Here’s some good news: you don’t need to book an expensive international flight to find warm sunshine this winter. The United States is home to dozens of incredible warm-weather destinations where you can escape the cold and enjoy the winter months for once.  

These aren’t just places where the temperature rises above freezing – these are destinations where you’ll genuinely forget it’s winter.

Trade Snow Boots for Flip-Flops  

Imagine walking barefoot on sun-warmed sand in January, hiking through cactus-filled deserts under bright blue skies, or sipping tropical cocktails by a resort pool while your neighbours back home shovelling snow.  

From tropical Florida keys to the sunny deserts of Arizona, from California’s perfect beach weather to the balmy southern charm of South Carolina, we’ve found warm winter escapes for every type of traveller.

Whether you’re looking for a romantic couples retreat, an active outdoor adventure, or simply a quiet place to relax in the sunshine, you’ll find your perfect winter getaway on this list.  

1. Key West, Florida: Tropical Vibes Without Leaving the US  

At the very southern tip of Florida, Key West feels more like a Caribbean island than an American city. The moment you arrive, you’ll notice the slower pace of life, the colourful Victorian houses, and the constant warm ocean breeze carrying the scent of saltwater and tropical flowers.

This is the kind of place where flip-flops are acceptable footwear everywhere, even at nice restaurants.  

What makes Key West so special in winter? First, the weather is perfect – daytime highs in the mid-70s to low 80s from December through March, with ocean temperatures warm enough for comfortable swimming.

Second, the island has an infectious festive spirit year-round, but especially during the winter months when snowbirds flock here to escape colder climates.  

Don’t miss walking down lively Duval Street, where you’ll find everything from Hemingway’s famous six-toed cats at his former home to lively bars with live music pouring out onto the sidewalks.

Make sure to catch at least one sunset celebration at Mallory Square, where street performers, local artists, and food vendors create a nightly party as the sun dips below the horizon.

For adventure, take a boat trip to Dry Tortugas National Park to snorkel in some of the clearest waters you’ll ever see, filled with colourful tropical fish and coral reefs.  

Best time to visit: December through March offers the most reliably warm and dry weather (75-80°F daily). January can be particularly nice, as it’s after the holiday crowds but before the spring break season begins.  

2. Phoenix, Arizona, Sunny Desert Escape  

Phoenix offers the perfect antidote to winter blues with its reliably sunny skies and warm desert climate. While much of the country is bundling up against freezing temperatures, Phoenix residents are enjoying daytime highs in the pleasant 60s and 70s throughout the winter months.

The desert air feels wonderfully warm compared to the humid summer heat, making winter the ideal time to visit.  

The city is surrounded by stunning desert landscapes that take on a special beauty in winter. Hiking trails that would be dangerously hot in summer become perfectly enjoyable, with popular routes like Camelback Mountain offering breathtaking panoramic views of the valley below.

After your hike, cool off at one of Phoenix’s many luxurious resort pools. Many hotels offer day passes so you can enjoy their amenities even if you’re not staying overnight.  

Downtown Phoenix and neighbouring Scottsdale offer excellent dining and cultural attractions. Old Town Scottsdale is particularly charming, with its Southwestern architecture and art galleries showcasing Native American and contemporary works.

It also has excellent restaurants serving everything from authentic Mexican cuisine to modern American fare.

Don’t miss the chance to try some local specialities like prickly pear margaritas or Sonoran hot dogs.  

Pro tip: While Phoenix is warm year-round, January and February offer the most comfortable temperatures for outdoor activities, typically ranging from 65-75°F during the day and cooling off to perfect sleeping weather at night.

3. San Diego, California: Perfect Weather All Year  

San Diego’s famously mild climate makes it one of the best winter sun destinations in the country. While “winter” here might mean wearing a light sweater in the evening, daytime temperatures typically stay in the mid-60s even in January and February – perfect for beach walks and outdoor dining.  

The city’s coastal location means you’re never far from beautiful ocean views and that fresh, salty sea air. La Jolla Cove is particularly stunning, where you can watch seals and sea lions sunbathing on the rocks just offshore.

Nearby, the tide pools at low tide reveal a fascinating world of colourful sea anemones, starfish, and other marine life.  

Balboa Park is another must-visit, with its beautiful Spanish Colonial Revival architecture housing numerous museums, theatres, and the famous San Diego Zoo. The park’s gardens are lovely year-round, with something always in bloom.

Downtown, the Gaslamp Quarter offers excellent dining and nightlife options, from casual breweries to upscale cocktail bars.  

What sets San Diego apart is how easy it is to enjoy outdoor activities year-round. Whether you want to kayak in the bay, bike along the boardwalk, or simply relax on the beach with a good book, San Diego’s winter weather makes it all possible while much of the country is stuck indoors.  

Why it’s great: You’ll forget it’s winter while comfortably wearing shorts and sandals in January when much of the country is dealing with snow and ice.  

4. Maui, Hawaii – Ultimate Winter Paradise  

For those who want to truly escape winter, Maui offers tropical perfection. Winter temperatures stay around 80°F with warm ocean waters perfect for swimming and snorkelling.  

The famous Road to Hana is even more enjoyable in winter when waterfalls flow strong after seasonal rains. Don’t miss sunrise at Haleakalā volcano or the traditional Old Lahaina Luau. Whale-watching season peaks from January to March, when humpbacks visit Maui’s warm waters.  

5. Palm Springs, California: Desert Chic Retreat  

Palm Springs combines midcentury modern style with perfect winter weather. Days are warm (70s-80s) while nights are cool – ideal for poolside lounging by day and stargazing by night.  

Tour iconic architecture, ride the aerial tramway for mountain views, or relax at one of the many stylish hotels. The city’s numerous spas offer perfect places to unwind when you escape winter’s stress.  

6. South Padre Island, Texas – Quiet Beach Getaway  

This Gulf Coast island offers warm winter temperatures with fewer crowds than Florida. Enjoy dolphin-watching tours, sandcastle-building lessons, and fresh Gulf seafood.  

Winter is the perfect time to visit South Padre Island – temperatures are comfortable, hotel rates are reasonable, and you’ll have the beaches mostly to yourself.  

7. Sedona, Arizona – Red Rock Wonderland  

Sedona’s stunning red rocks glow in the winter sun, making it one of the most beautiful warm US spots to escape winter. Hike Cathedral Rock at sunset, visit energy vortex sites or enjoy outdoor spa treatments with mountain views.  

The town’s art galleries and New Age shops offer plenty to explore when you’re not out enjoying the natural beauty.   

8. Gulf Shores, Alabama – Affordable Beach Escape  

For budget-conscious travellers looking to escape winter, Gulf Shores offers warm weather without high prices. Enjoy white sand beaches, fresh seafood, and nature trails in Gulf State Park.  

Winter visitors can often find great deals on beachfront condos, making this an affordable alternative to Florida.  

9. Las Vegas, Nevada – Warm Desert Nights  

Vegas isn’t just for gambling – it’s a great place to escape winter with warm days and exciting nights. Many hotels have heated pools open year-round, and nearby Red Rock Canyon offers stunning hiking.  

Winter is one of the best times to visit Vegas, with comfortable temperatures and special holiday displays on the Strip.  

10. Charleston, South Carolina – Southern Charm  

Charleston offers mild winter weather with daytime temperatures in the 60s – perfect for exploring historic streets and nearby beaches. The city’s famous restaurants are less crowded in winter, and hotel rates are more reasonable.
