What are seasonal buoys used for?

Seasonal buoys are specifically designed to mark navigational conditions that change with the seasons. This includes variations in water levels, currents, or the presence of floating debris that may occur as a result of seasonal changes. Unlike permanent navigational aids, which indicate consistent routes or landmarks throughout the year, seasonal buoys provide critical information that helps vessels navigate safely during different periods. They ensure that mariners are aware of temporary hazards or arrangements that may not be present at other times of the year. Thus, they play an essential role in promoting safe navigation based on the specific conditions prevailing during a particular season.
