Site details

The north end of Monastery Beach (San Jose Creek Beach) on Carmel Bay, sitting on the eastern rim of the Carmel submarine canyon — a 200-yard swim can put a diver over 200 feet of water. Granite reefs and pristine kelp forest start close to shore, but the steep, coarse-sand beach produces violently plunging shorebreak and a washing-machine undertow. The beach is infamous for diver and wader fatalities (roughly 20 deaths since 2004, earning the nickname 'Mortuary Beach'); enter and exit only at the extreme north end and only on small-swell days.

reefshorewall

EXTREMELY DANGEROUS SHOREBREAK — steep beach with plunging waves that break directly on the sand, severe undertow, unstable coarse sand underfoot; knee-high waves can knock a geared diver down; multiple fatalities including non-divers; deep water (canyon) very close to shore; never turn your back on the ocean here
