Mahukona Anchorage

20° 11.0′ N · 155° 54.4′ W

The charted anchorage off the old Mahukona sugar landing, a sand-and-coral roadstead 6 nm southwest of Upolu Point that, with Nishimura Bay next door, is the last stop before the Alenuihaha Channel.

Practical

Coordinate is the NOAA-chart anchorage point in the state's Anchorages GIS layer. Coast Pilot (October 2026): anchor 0.2 mile southwest of Makaohule Point in 10 to 15 fathoms (60-90 ft), sand and coral; an anchorage with less wind is 0.3 mile northwest of the point about 400 yards off the beach. Strong offshore winds with violent gusts from varying directions are frequent in normal northeast trades, so lay plenty of scope and have a second anchor ready. The inshore current usually sets north; measured drifts were about 0.2 kt with up to nearly 1 kt either way. Mahukona is the one west-coast spot where the regular sea-breeze pattern does not hold. Small-boat landing only at the head of the bight. For shallower water and sand, Noodle's Notes prefers Nishimura Bay a few hundred yards north.
