CDIP buoy 196 sits off Ritidian Point on the northern tip of Guam. Because it's exposed to the open ocean from the north, west, and east, it's often the first to show incoming north-Pacific swells before they reach the island's east-coast reefs. Paired with Ipan (121), the two buoys give a complete picture of what's hitting Guam.

Reading swells before they wrap to other Guam coasts
Wind
Trade winds and exposed to all directions. Calmest in the dry-season transition months.
Ritidian's exposure makes it noisier than Ipan — short-period wind chop reads big. Look at period more than height to call swell quality.
Ritidian (196) reads what's coming in. Ipan (121) reads what's actually hitting the east coast surf. Watching both lets you see swells building before they arrive. Da Buoys' favorites view shows them side by side.
