A rip current is a narrow stream of water running out from the shore through the surf, often where fewer waves break. Caught in one, swim across it, along the shore, then back in.
The surf zone forecast for Nantucket MA, and the waves at buoy 44020, 17.4 mi away.
Wave height is the significant height: the mean of the highest third of the waves. The period is the time between the waves carrying the most energy.
