Flow in surfing terms is when a surfer rides a wave from start to finish without hesitations or stoppages. Where a surfer performs a series of manoeuvres with speed during and between the manoeuvres attempted. It’s also a major component of really great surfers, and can be the point of difference in scoring terms when they compete. Think of the Kelly’s and Steph’s in the world. Not only can they perform great moves, but they look beautiful at the same time because of the flow they display.
