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 $30, you get a full-day standup paddleboard rental for one (up to a $60 value) from OEX Sunset Beach on Pacific Coast Highway in Sunset Beach.

Offering rentals, repairs, and accessories for kayaks and standup paddleboards, OEX Sunset Beach lets marine aficionados commune with the water in high style. A new trend in aquamotion, standup paddleboarding has water jockeys stand atop a surfboard-like plank with a long paddle, used for propulsion and swatting away bellicose mermen. Though the day rental is relegated to the harbor, the smooth water and placid demeanor of the enclosed space make the ideal environment for learning the ins and outs of steering and balancing on the board without complicating factors like tall waves or high winds.

Before embarking, OEX’s experienced guides will debrief paddleholders in basic paddle techniques, safety instructions, and proper life-jacket accessorizing. Because accidental splashes and coastal breezes are possible, OEX recommends dressing in trunks and a T-shirt, and accidental body-water interface should be prepared for with a toted towel or duck-feather suit.

Though OEX Sunset Beach sometimes offers its own early-bird specials for weekend mornings, this Groupon still offers the best deal available.
