What is it called when the waves hit the beach with so much frequency that the water is churning like a washing machine? On days like that you will often find that many beginner-intermediate surfers have trouble pushing through the whitewash and the currents are sometimes very strong as well.
I know there must be a name for this...it would make it so much easier for me to describe when warning other surfers about the conditions.
What is going on when it's like this? Is it a groundswell? Does it only happen at certain types of breaks? If I had to guess, it occurs in bays that funnel in swells from different directions creating chaotic conditions. Am I close?
