During a hurricane, waves in the middle of the ocean can reach significant heights due to the powerful winds and intense storm conditions. The size of waves in a hurricane depends on various factors, including the storm's intensity, wind speed, duration, and the fetch—the distance over which the wind blows without obstruction.
In the core of a hurricane, known as the eyewall, where the strongest winds are concentrated, waves can reach extraordinary heights. It is challenging to measure wave heights accurately in the middle of the ocean during a hurricane, as it is a hazardous environment for direct observations. However, estimates can be made based on historical data and modeling.
In extreme cases, significant wave heights in the range of 40 to 50 feet (12 to 15 meters) or even higher have been reported in hurricanes. These towering waves are typically associated with the most intense hurricanes, such as Category 4 or Category 5 storms, which have sustained winds of 130 mph (209 km/h) or more.
It's important to note that while these wave heights are observed in the open ocean, they can reduce in size as they approach coastal areas, depending on the local bathymetry (ocean floor topography) and other factors.
The size and strength of waves during a hurricane pose significant dangers to maritime activities, making it crucial for vessels to avoid these areas and for coastal communities to prepare for the potential impacts of storm surge and high waves.
