Tide Pool Party: Where to Spot Cool Marine Life Near Seattle

Grab your rubber boots and low tide field guide–there are some fantastic minus tides in Puget Sound this summer!

There are a few things in life that you can rely on with absolute certainty. One of those is the rhythm of the sea. Twice a day, the tide will come in (high tide!) and twice a day, the tide goes out (low tide!).

A few times per year, usually in the months around the summer solstice, we get super low minus tides at midday, say anywhere from -2 to -4. This pattern lasts for a few days each month. (A “minus tide” is any tide below zero, and zero is defined as the local mean lower low tide.) The minus tides are when you’ll get exposed tidepools for exploring the cool critters that live in them, and when you want to go digging for clams and oysters. (By the way, in the months around the winter solstice we also get low minus tides, but those low tides occur in the middle of the night, hence why winter razor clamming on the coast is often done by headlamp!)

When the tide goes out, it leaves behind small saltwater pools in the depressions and crevices of rocks and sand, resulting in a diverse, albeit temporary, aquatic ecosystem. Tidepooling is when you head out to a beach during a low tide and poke around the rocks, nooks and crannies to spot exposed aquatic life. It’s easy, fun, and free! Anyone can go tidepooling with just a little bit of knowledge and some basic gear you probably already have. And at many beaches throughout Puget Sound, experienced marine naturalists are on hand during low tides to help you discover cool critters.

Tide Pool Party: Where to Spot Cool Marine Life Near SeattleYou really just need three things to go tidepooling:

  1. A tide chart. You can pick this up for a few bucks at any hardware store, or find a tide chart free as an app or online.
  2. Some waterproof boots. The best rain boots for tidepooling are high (up to your knees ) and have great traction on the bottom to keep you steady on wobbly rocks. These tall Hunter rain boots are perfect. My kiddo really likes his Bogs which are a few inches taller than the average kids’ rain boots. If you wear ankle rain boots you risk flooding them if you misjudge the water depth when taking a step. (yes, this has happened to me!) Personally, I find our Salish Sea waters to be too chilly for wading around in sandals unless it’s a scorching hot day.
  3. field guide to help you identify marine critters. The most basic guide is the waterproof Mac’s Field Guide to Northwest Coastal Invertebrates. This is the guide my son uses (see the photo); he’s very into marine biology and still it’s sufficient for him. For a more comprehensive guidebook, check out the Beachcomber’s Guide to Seashore Life in the Pacific Northwest.

Ready to spot some vibrant sea stars and scurrying crabs? Here’s how you can make the most of our awesome minus tides this summer!

When to Go Tidepooling

There are many resources where you can view current and future tide times. On my phone I use a free app called Tide Alert and online go to tides.net, then click on the state and city/region to get a tide chart for the current month. I like how it is displayed in calendar form and can quickly home in on where the minus tides are, and get more detailed info by hovering over a particular day.

As you’ll see in this screenshot, there are mid-day minus tides from July 10-16, 2018. The lowest tide will be -3.7 feet at 11:38am on July 13th. There’s a similar pattern in August, with minus tides occurring August 8-13, 2018.

Tide Chart for July 2018

When there are super low minus tides during the day, beach naturalists are stationed at popular tide pool beaches throughout Puget Sound to help you find cool critters.  

Arrive on the beach at least one hour before the low tide time. (We usually arrive about two hours before low tide because my son really loves tidepooling and likes to see as much as possible!) Follow the waters’ edge as it recedes, exploring tidepools as they are revealed. After the low tide time has passed, you should move toward shore and maintain a safe distance from the water’s edge as incoming tides can be swift and unpredictable. Never turn your back on the ocean.

Fun Fact: The lowest tide ever recorded on a Seattle beach was -5 ft in 1916.

 

Tips and Etiquette for Exploring TidePools

The intertidal zone is an incredibly fragile habitat. While the critters here are adapted to pounding surf and frigid temperatures, they aren’t used to stomping boots and prodding fingers. Follow these basic tips to help you explore safely and without harming the aquatic wildlife.

  1. Step with care. Avoid crushing anemones and tiny crabs by stepping instead on bare rock or sand. Walk very slowly on seaweed which can be hazardously slippery.
  2. Don’t move animals from one place to another. Don’t pry critters off of rocks or overhandle crabs. You will see naturalists take great care when picking up critters to show them to you, and they’ve been trained how to do this with minimal impact to the animals. Watch and learn.
  3. Touch very gently, and use wet fingers. If you wish to touch a sea star or feel the fringe on an anemone, a soft touch with a wet finger is the least disturbing to them.
  4. Beware of things that hurt. The bite of the red octopus really hurts. The sting of a jellyfish does, too. Don’t touch these critters.

Tidepooling at Seahurst Park in Burien.

During a minus tide, any public beach is going to have depressions in the sand or small pools that host a variety of marine life. But some specific beaches are particularly great for tidepooling because they have large rocks that create sizable tidepools with lots of crevices and nooks for critters to hide in. My family’s favorite place at low tide is the Charles Richey Sr Viewpoint portion of Alki Beach Park (also known as Constellation Point) in West Seattle. Here are some more great free spots for low tide beachcombing and tidepooling in and around Seattle.
