Swell is the collection of waves moving away from a storm in the ocean. Although the waves will all be of different size and power and heading in slightly different directions we can tend to talk about averages of all these waves as one discreet swell.
Swell continues to move under winds and waves that have long since changed direction, it can even head in the opposite direction as the wind and waves. Swell can cross an ocean of a thousand miles, something that is recognised and studied by surfers from Hawaii to Cornwall. The fact that the water can store this wind energy explains why we often experience a rougher sea than the wind that was forecasted or felt before jumping in.
