What a frozen day at the beach looks like when the waves turn to slush

You've arrived in Nantucket for your big international surfing adventure in New England. Okay, it's no Hawaii, but the waves are good.

Except, of course, when it's February, freezing and the waves have turn into slush.

"When I pulled up to the beach I could see the horizon just look strange," photographer Jonathan Nimerfroh, who lives on Nantucket, wrote me in an email. "When I got to the top of the dunes I saw that about 300 yards out from the shoreline the ocean was starting to freeze."

Nimerfroh wasn't out on the Nantucket beaches for surfing last Friday — it wouldn't have been good anyway because of the winds coming in from the southwest, which he says would typically make for rough or choppy conditions. But he did shoot some amazing images of the 2- to 3-foot slush waves.

"What an experience to be absolutely freezing on the beach, watching these roll in, while I mind-surfed them," he says.
