Happy New Year! Every year for more than the last fifty years, brave or foolhardy Dutch men, women, and children have been celebrating New Year’s Day by jumping into the sea. Called the ‘Nieuwjaarsduik‘ (New Year’s dive), an estimated 25,000 or so plunge into the icy water each January 1st, at some 60 locations across the Netherlands. The largest dive takes place yearly at the seaside resort of Scheveningen, where typically 10,000 or so hardy souls put on little red knot caps, run screaming into the ocean and then run screaming back. Here is a video of the bone-chilling festivities at Scheveningen last year.
