Shortest Distance from Cuba to Florida: What Is It?
The shortest distance from cuba to florida is about 90 miles (145 kilometers). This measurement stretches between Cuba’s northern coast—specifically, the area near Havana—and Key West, Florida, which is the southernmost point of the contiguous United States.
The line, crossing over the Florida Straits, is more than a geographic detail. It’s baked into every conversation about crossstrait migration, diplomacy, weather tracking, and marine ecology.
The Geography of the 90 Miles
Cuba sits south of Florida and is the largest island in the Caribbean. Key West, part of the Florida Keys, is the nearest urban point in the US. The Florida Straits is a deep, turbulent sea channel, with ocean currents (notably, the Gulf Stream) running northwest from Cuba’s coast to the Atlantic.
Despite the proximity, you cannot see Cuba from Key West with the naked eye—atmospheric conditions and the earth’s curvature get in the way.
Why the Shortest Distance from Cuba to Florida Matters
Migration: The 90mile stretch has defined the journey for countless refugees and migrants escaping Cuba for the United States, especially after the Cuban Revolution of 1959. Rafts, boats, and even swimmers—like Diana Nyad—have made (or attempted) the crossing against heavy odds. USCuba Policy: The “wet foot, dry foot” policy—now ended—was built on this proximity, allowing Cubans reaching US land (but not those intercepted at sea) to stay. Trade, Law Enforcement, and Border Control: The closeness creates constant tension and cooperation between US and Cuban authorities: drug smuggling, human trafficking, and searchandrescue operations are routine. Weather and Ecology: Storm systems frequently travel across the Straits, impacting both islands and the US mainland. The marine ecosystem allows for migration of countless species of fish, turtles, and marine mammals.
The Human Side: Stories Across the Straits
For those living along Cuba’s northern shores or on Key West, the shortest distance from cuba to florida is not abstract. It’s a real, highstakes passage. People have made homemade rafts, braved storms, and risked everything to cross. Success stories and tragedies alike are part of the collective memory on both sides of the water.
Attempts to Bridge or Cross the Distance
Boat traffic: Private crafts, ferries, and occasional sanctioned trips make the journey, though most Americans cannot legally visit Cuba directly thanks to embargo restrictions. Swims: Diana Nyad’s 2013 swim from Havana to Key West after multiple failed attempts put a spotlight on the endurance required—over 50 hours in the open sea. Ferries and flights: In the past, ferries ran regularly between the countries. Today, flights are more common, though subject to shifting diplomatic rules.
A bridge or tunnel has been floated as an idea over the years. In practice, deep water, hurricanes, and international politics render this fantasy out of reach.
Measuring the 90 Miles: Points and Myths
Havana is the reference point for most “90 mile” conversations, but technically the closest part of Cuba may be a bit east of the city. Key West’s “90 Miles to Cuba” marker remains a tourist staple, even though the actual mileage is slightly longer depending on measurement points.
Weather Across the Straits
Hurricanes, tropical storms, and prevailing winds cross easily between Cuba and Florida, sometimes strengthening over the warm waters of the Straits. Both territories face similar patterns of weather and have a mutual interest in storm tracking and disaster response.
The Political Impact
The shortest distance from cuba to florida means geography always outruns politics. Despite decades of embargo, travel bans, and limited diplomacy, the physical closeness maintains economic, cultural, and historic ties—visible in Miami’s CubanAmerican population, Key West cuisine, and beyond.

Final Thoughts
The shortest distance from cuba to florida is more than a number—it’s a powerful reality for migration, diplomacy, ecology, and culture. The closeness drives stories of daring escapes, tense standoffs, and ongoing change. For millions in Florida and Cuba alike, those 90 miles are both barrier and bridge, shaping life on both sides of the Straits, every single day.
