It’s no secret that Florida attracts beach-goers from all over the world, all year long. While some states experience blistering cold weather and snowfall, Florida’s December is known to be mild and comfortable. This is what makes Florida a popular destination, even during the winter months!

With hundreds of miles of coastline, you’ll have no issue finding a place to sink your feet in the sand and avoid the winter blues on a beach vacation. Florida is known for its tropical weather all year long, making it the perfect December destination. 

Although all the Florida beaches are spectacular, if you want the warmest beaches during the winter months, it is best to avoid north Florida beaches.

3. Miami Beach 

Located in the heart of Miami, Miami Beach is a popular tourist attraction with plenty of action. The year-round sunny days and warm weather makes this beach one of the best places for swimming, sunbathing, and water sports like jet skiing and parasailing.

Miami Beach is broken into three sections:

  • North Beach
  • Mid Beach
  • South Beach

If you’re looking for activities beyond the beach, Miami has tons of cultural attractions such as art galleries, museums, and theaters. My favorite is Wynwood, which is known for its Instagram-worthy murals.

One of the biggest reasons people visit Miami is because it is home to some of the best restaurants and nightclubs in the country! If you want to truly experience Miami, book a reservation for Papi Steak which combines the high-end luxury of a delicious meal with a DJ-bumpin party that lasts all night.

Think jazz lounges and cocktail bars nestled between a luxury shopping district and you’ve just described The Galleria!

Some of my favorite spots are Blue Martini and The Parrot Lounge, which has been around since 1970! 

Located just an hour north of Miami Beach, Fort Lauderdale Beach offers visitors enjoyable weather, Atlantic ocean beaches with turquoise waters and palm trees, intriguing art galleries, and world-class restaurants.

There are also a ton of opportunities to enjoy the natural beauty of Florida at parks and museums such as Bonnet House Museum & Gardens and Marti’s Meditation Garden.

Bowman’s Beach is one of the beaches located on the island, and my personal favorite because of the amenities, including restrooms, picnic tables, and grills. 

Another big reason I love Bowman Beach is because of the seclusion and preservation that makes it home to an abundance of wildlife. Bowman Beach happens to be a popular destination for birdwatchers and nature lovers, with numerous species of birds and other wildlife such as pelicans, rabbits, stingrays, and dolphins.

Or, if you want to shop like a local, take your wallet to Worth Avenue, where the shopping is world-renowned. Palm Beach is also known for its championship golf courses including the Ocean Course at The Breakers, The Staple, Champion or Fazio at PGA National Resort & Spa, and Old Palm Golf Club.

Delnor Wiggins Pass State Park boasts some of the most pristine shoreline in all of Florida, offering a secluded and serene feeling. The sugar sand beaches and warm water that line Florida’s Gulf Coast are a beauty you just can’t beat.

During December, this area averages temperatures between 70°F and 75°F (21 to 24°C). 

One of the best things about this state park is the amenities, the ​​concessionaire has food/beverages and rentals that include paddleboards, kayaks, canoes, umbrellas and beach chairs, so all you have to bring is yourself! This is also a popular spot for trophy fishers, with the boat launch located at Turkey Bay which leads to the river and the Gulf of Mexico.

9. Siesta Key Beach, Siesta Key 

Siesta Key offers beachgoers a unique experience, which is why so many people love it.

In December, you can expect the average daily temperature in Siesta Key to be around 74°F (23°C). 

Siesta Key is a typical beach town and the perfect place to try out a new watersport such as parasailing, kayaking, surfing, or paddleboarding. The Gulf of Mexico is also a great place to fish, so be sure to book a fishing charter or even a sunset cruise if you just want to go sightseeing.

Another plus to Siesta Key is that is a short drive to downtown Sarasota, which offers great nightlife, and museums. 

Average sea temperature in December: 68.50°F (20.30°C)

10. Clearwater Beach 

Clearwater Beach is easily one of the most popular beaches in Florida, for good reason. Located on the southwest coast of Florida just west of downtown Tampa, this highly ranked beach has a ton to offer locals and visitors. In December, the average temperature ranges from 53° at night to average highs in the mid 70°s. 

The calm waters of Clearwater Beach make it a great spot for watersports, while the white sand beach is lined with sunbathers and those who enjoy long walks on the beach. If you want to get away from the beach, I’m a big fan of the Clearwater Marine Aquarium and Alligator & Wildlife Discovery Center. Clearwater also offers great local seafood spots like Barefoot Beach House and Badfins Food & Brew. There’s even a craft beer trail if you need to wash it down with a few brews!
