A storm blew up the coast Friday night, and we heard the wind howl in the dark. Although there's no scale on the picture to give a sense of the height of the in-coming surf, I estimated the waves to be between 8 and 10 feet on Saturday, and they probably much higher the previous night.
The picture does show, however, the spray from the pounding waves.
I don't know where along the beach the surfers were on Saturday, but they showed up Sunday.
