If you’re wondering if it’s worth visiting Miami in December, during this time of the year temperatures can reach up to 75-80 degrees Fahrenheit (24-27 Celsius). It’s the beginning of the dry season, so you can expect blue skies accompanied by a crisp breeze and a little rainfall.

While on Miami Beach, you can bask in the sun, swim on its crystal clear blue water, walk on the boardwalk, rent a jet ski, take a sunset cruise or even better, a private yacht cruise with champagne.

In addition, Miami Beach has an iconic nightlife scene that makes it one of the best places to visit if you want to experience a unique blend of culture and fun!
