Swell height refers to the average size of the swell out at sea. This is measured from the peak to the trough and the seconds between one peak and the next using historical and real time data gathered from offshore buoys. Wave height is the average wave size a surfer may expect to see when reaching the beach.

How do you tell if the ocean will be calm?

The wind is responsible for creating waves and swell, and the easiest indicator of sea conditions is wind speed. Wind speed is measured in knots, which are based on nautical miles. Five-knot winds or less will be barely noticeable, and you should have calm seas and ideal boating conditions.
