The “Wave Period” product provides forecasts every three hours for the next seven days, indicating the interval between waves in seconds. This information is crucial for navigation, as wave period affects the behavior of vessels at sea. A longer wave period generally indicates smoother and more stable waves, making navigation easier, while a shorter period can result in choppier waves that challenge vessel stability. Navigators can use this data to plan safe and suitable routes, ensuring smoother and more efficient sailing, while also optimizing activities such as fishing and maritime tourism.
