About Diamond Head (Cliffs)

The reef below Diamond Head lighthouse, reached down steep trails from Diamond Head Road. Ledges and deeper water close in, but it is open to south swells and the wind, with no easy way out on rough days and no lifeguards.

Diamond Head (Cliffs) faces south (190°): swell from that side arrives head-on.
Swim or kayak in from shore, or go by boat from Ala Wai Small Boat Harbor.
Water 100 ft (30 m) deep starts about 0.9 km out.
Blue water (300 ft / 100 m and deeper) is about 1.4 km out.

What spoils the visibility here

South swells, mostly May to September, reach it.
It is sheltered from the usual trade winds; Kona (southerly) winds and swells are its weak spot.
Heavy rain sends brown runoff into the water for a few days; Hawaii DOH posts Brown Water Advisories when it does.
