Chase the minus tide
Tide tables list heights relative to an average low. A negative number -- like -1.2 ft -- means the water pulls back further than usual and the low zone comes out. Aim for 0.0 ft or lower.
Orange County, California -- rocky intertidal
Low Tide Club is a field guide for anyone curious about the tide pools between Corona del Mar and Dana Point -- what lives there, when to go, and how to visit without hurting anything.
The rocky shore is stacked in bands. Each band spends a different amount of time underwater, and each one has its own residents. Learn the bands and you will know where to look.
Above high tide -- wet only from spray
The driest band. Tiny periwinkle snails and the smallest barnacles wait out long dry spells sealed shut. If it lives here, it is built to hold its breath.
Underwater only at high tide
Acorn barnacles, limpets, and lined shore crabs. Everything here clamps down, hides in cracks, or scuttles fast. Watch where you put your feet.
Exposed and covered about twice a day
The busiest neighborhood. Mussel beds, carpets of aggregating anemones, turban snails, hermit crabs, and the occasional ochre sea star working its way through dinner.
Exposed only during the lowest tides
The prize. Giant green anemones, purple urchins, sea hares, bright nudibranchs, and -- if you are patient -- an octopus tucked into a crevice. You only get here on a minus tide.

Arrive about an hour before the listed low. You get time to walk out as the water drops, and you are heading back while the tide is still in your favor.
In Southern California the best winter lows tend to fall in the afternoon and evening. Summer lows lean toward early morning. Bring a light in winter.
Sneaker waves happen even on calm days. Keep the ocean in view, stay off rocks that are getting wet from fresh spray, and leave with plenty of time to spare.
