Within the North Atlantic Ocean, a Category 3 hurricane is a tropical cyclone, that has 1-minute sustained wind speeds of between 96–112 knots (110–129 mph; 178–207 km/h; 49–58 m/s). Since the beginning of the Atlantic hurricane database in 1851, 162 tropical cyclones peaked at Category 3 strength on the Saffir–Simpson scale in the Atlantic basin, which covers the waters of the Atlantic Ocean north of the equator, the Caribbean Sea, and the Gulf of Mexico. This list does not include hurricanes that intensified further to a Category 4 or 5, the latter being the highest ranking on the scale.
