Best Beaches to Visit in America in January
Last Updated on October 13, 2025 by Boatsetter Team
When winter has most of the country bundled up, America’s southern coasts and islands are still serving sunshine, turquoise water, and warm breezes. January is one of the best times to trade snow for sand — and the perfect excuse to plan a boat day while you’re at it.
From Florida’s Gulf Coast to California’s cliffs, here are the best beaches in the U.S. to visit in January — each with its own local vibe, water adventures, and reasons to drop anchor.
1. Miami Beach, Florida
Average High: 76°F
Why Go: The energy in Miami never slows down — and January brings mild temps, light crowds, and crystal-clear water. Lounge on South Beach, stroll Ocean Drive, or charter a boat from nearby Boatsetter Miami to cruise Biscayne Bay or the Venetian Islands.
Boatsetter Insight: Miami is the #1 winter boating market in the country, with high demand for half-day yacht charters, sandbar trips, and sunset cruises.
2. Key West, Florida
Average High: 74°F
Why Go: The southernmost point in the continental U.S. is a January paradise — turquoise water, live music on Duval Street, and snorkeling adventures at Dry Tortugas National Park.
Don’t Miss: Book a Key West boat rental for reef diving or a day trip to secluded sandbars where dolphins often play.
3. San Diego, California
Average High: 67°F
Why Go: With 70 miles of coastline and perfect weather year-round, San Diego is unbeatable for both surfing and sailing. Head to La Jolla for sea lions and tide pools, or Pacific Beach for that laid-back Southern California energy.
Boatsetter Tip: Winter is prime whale-watching season — humpbacks, grays, and even orcas migrate offshore.
4. Naples, Florida
Average High: 77°F
Why Go: The Gulf’s calm waters and soft white sand make Naples a top pick for peaceful winter escapes. January brings warm weather, golden sunsets, and ideal fishing conditions.
Boatsetter Insight: Book a Naples fishing charter or cruise to Keewaydin Island for a private picnic.
5. Honolulu, Hawaii
Average High: 80°F
Why Go: January in Hawaii means whale migrations, beach barbecues, and warm tradewinds. Waikiki Beach is lively year-round, while Oahu’s North Shore draws surfers chasing legendary waves.
Boatsetter Tip: From snorkeling at Hanauma Bay to cruising along Diamond Head, Oahu offers some of the best boating in the Pacific.
6. Clearwater Beach, Florida
Average High: 72°F
Why Go: A family-friendly gem with powdery sand and calm, clear water. January brings fewer crowds but plenty of sunshine — perfect for beach days and dolphin cruises.
Don’t Miss: Charter from Boatsetter Tampa Bay to explore nearby islands like Caladesi and Honeymoon Island.
7. Santa Barbara, California
Average High: 65°F
Why Go: This coastal escape combines Mediterranean charm with California sunshine. Stroll the waterfront, sample local wine, and take in postcard-worthy harbor views.
Boatsetter Insight: Santa Barbara’s harbor is ideal for romantic sunset sails — and January skies make the colors pop.
8. Islamorada, Florida Keys
Average High: 75°F
Why Go: Known as the “Sportfishing Capital of the World,” Islamorada offers world-class angling and laid-back island life just 90 minutes south of Miami.
Boatsetter Tip: Pair your trip with a guided Islamorada fishing charter — tarpon, mahi-mahi, and snapper are plentiful in winter.
9. Kiawah Island, South Carolina
Average High: 63°F
Why Go: This barrier island near Charleston offers quiet beaches, bike paths, and wildlife galore. It’s the perfect spot for travelers who want nature over nightlife.
Boatsetter Insight: Charleston’s waterways are peaceful in winter — book a Charleston boat rental for dolphin watching or a Lowcountry sunset cruise.
10. Destin, Florida
Average High: 64°F
Why Go: Known as the “World’s Luckiest Fishing Village,” Destin offers clear emerald water and sugar-white sand — without the peak-season crowds.
Don’t Miss: Head out on a Destin boat charter for offshore fishing or a day at Crab Island — a local favorite even in winter.
Bonus: St. John, U.S. Virgin Islands
Average High: 82°F
Why Go: Technically not the mainland, but still part of the U.S. — no passport needed. St. John is paradise in January, with coral reefs, turquoise coves, and national park beaches that feel a world away.
Boatsetter Tip: Charter a yacht and island-hop between St. Thomas, St. John, and Water Island for the ultimate winter escape.
