Each winter, the highest tides of the year return to Puget Sound. For anyone who owns, or hopes to own, a home on the water, king tides offer a rare look at how a shoreline truly performs, and a reminder of why a little preparation goes a long way.
On a calm summer afternoon, it's hard to picture the water reaching much farther than the edge of the beach. Then winter arrives, and a handful of mornings bring tides that climb higher than any other time of year. Driftwood shifts, beaches disappear, and water rises to the base of bulkheads, docks, and seawalls around the island.
These are king tides, and on Bainbridge Island, they're as much a part of the seasonal calendar as holiday lights and winter storms. Whether you're a longtime waterfront homeowner or touring properties for the first time, understanding king tides can help you make more confident decisions about life on the shoreline.
What Is a King Tide?
"King tide" isn't a scientific term. It's a common way to describe the highest tides of the year, which happen when the moon and sun align and the moon's orbit brings it closer to Earth. In Washington, the most extreme tides typically occur between November and February.
On their own, king tides are a natural and predictable part of the tidal cycle. When they arrive alongside a winter storm, strong winds, or low barometric pressure, though, water levels can rise even higher than predicted. That combination is what waterfront homeowners pay the closest attention to.
When to Expect King Tides This Winter
According to Washington Sea Grant's King Tides Calendar, the highest tides near Bainbridge Island this season are expected on the following dates, based on the Seattle tide station:
· November 25 to 29, 2026
· December 25 to 29, 2026
· January 23 to 27, 2027
· February 20 to 24, 2027
The highest tides typically fall in the early to mid-morning hours, with the season's peak predicted for late January. That means Thanksgiving weekend and the week after Christmas are two of the best opportunities to see king tides firsthand, whether you're walking your own shoreline or visiting one of the island's many public road ends and beaches.
What King Tides Reveal About a Waterfront Property
If you're considering a waterfront home, touring during a king tide is one of the most valuable things you can do. As we shared in our recent blog, The Myth of the Off-Season, winter offers a firsthand look at the reality of owning a home on the water. A king tide takes that one step further, showing you how a property responds when the water is at its highest.
While you're there, take note of a few key details:
· How close the water comes to the home, outbuildings, and septic areas.
· Whether waves reach the top of the bulkhead or seawall, and how it holds up.
· Signs of past erosion, such as exposed roots, undercut banks, or shifting stones.
· How docks, ramps, and floats sit at high water.
· Where driftwood and debris tend to collect on the beach.
Bank type plays a big role in what you'll see. A no-bank home may feel the effects of a king tide most directly, while a high-bank property is more likely to show how drainage and slope stability hold up over a wet winter. For a closer look at the differences, read our blog on Low Bank, High Bank, and No Bank waterfront on Bainbridge Island.
How Waterfront Owners Can Prepare
It's also a good time to know your property's flood zone and review your insurance coverage. If you notice changes along your shoreline after a king tide, document them with photos and reach out to a qualified specialist. Our Waterfront Home Contractors blog includes some of the professionals we trust most.
While you're out on the beach, consider taking part in the Washington King Tides program, which invites residents to safely photograph high water at their favorite shoreline spots. These images help communities around the state understand how coastlines are changing over time.
