About Miami Beach
Miami Beach sits on a barrier island between the Atlantic Ocean and Biscayne Bay, and its calling card is the Art Deco Historic District — roughly 800 pastel buildings from the 1920s and 1930s lining Ocean Drive between 5th and 23rd Streets. South Beach claims the iconic strip with its lifeguard towers and crowds, while Mid-Beach further north runs quieter past the Faena District and Eden Roc. The sea holds 28-30 °C from July through September, with Miami International airport about 20 minutes by the MacArthur Causeway.
