Tide pool tips
Arrive about an hour before low tide and head back as soon as the water turns.
Sneaker waves run far up rocky shores, especially on the Pacific. Never turn your back on the ocean.
Seaweed and barnacles are slippery and alive. Wear shoes with grip and step on bare rock or sand.
Touch gently with a wet finger, put rocks back as you found them, and leave animals and shells. Many tide pools are protected.
How these dates are worked out
For every spot we take NOAA's low tide predictions for the next 12 months. A low counts as a tide pool low when it's in that spot's lowest 10% and comes between an hour after sunrise and sunset, so there's light for the hour before it. Heights are feet above mean lower low water (MLLW), the zero on tide charts; below zero is a minus tide. Wind and swell can keep the water higher than predicted. Not for navigation.
