Instead of hunkering down with Netflix and hot chocolate during the East Coast’s recent cold snap, surfers Nick Hayden and Jamie Briard spent the first few days of January 2018 conquering icy waves in Nantucket, Massachusetts. The frothy swells resembled a frozen 7-Eleven Slurpee, so photographer Jonathan Nimerfroh, a friend of the athletes, grabbed his camera to capture the phenomenon, according to deMilked.
The freezing point for salt water is 28.4°F, but undulating ocean waves typically move too much for ice particles to form. At Nantucket’s Nobadeer Beach, however, conditions were just right for a thick layer of frost to form atop the water’s surface for several hours. Some of the slushy crests were even surfable before melting after about three hours, Nimerfroh told Live Science.
This is the second time Nimerfroh has photographed so-called “Slurpee waves." He captured a similar scene on February 27, 2015, telling The New York Times, “I saw these crazy half-frozen waves. Usually on a summer day you can hear the waves crashing, but it was absolutely silent. It was like I had earplugs in my ears.”
