Red sky at night is a sailor’s delight, but red sky at morning means the ship's been steered inside a volcano. Discover further aquaformation with today’s Groupon: for $114, you get a 90-minute surfing lesson for two from NY Surf School in Far Rockaway (a $230 value).

NY Surf School's private lessons introduce students to the action-packed pastime of riding a bucking wave. During the two-hour session, expert instructors—each soaked with more than 20 years of surfing experience—guide a pair of landlubbers out onto the ocean swells for a semi-private lesson, teaching them the mysterious ways of catching a wave and slapping it with a board until it agrees to wash them onto a beach littered with treasure. NY Surf School's lessons include board and wetsuit rental, and once the watery adventure comes to an end, surfers can head to the surf shop for a hot shower, rinsing off the sea's salt and pepper and relaxing after their core-strengthening, balance-improving lesson on the turf.
