King Tide Season is here
With the rainy season underway, the Pacific Northwest coast braces for more than just wet weather—it's the time of year for dramatic winter storms, big ocean swells, and the arrival of the annual king tides.

Known for producing some of the highest tides of the year, king tides are caused by the moon’s orbit drawing closest to Earth. The gravitational pull of the moon, especially when it aligns with the sun, creates a combined effect that leads to significantly higher-than-average tides. While visually impressive, these tides bring both natural wonder and potential destruction to the coastline.
Today, with a high tide exceeding nine feet and an impressive 20-foot swell, waves surged up to the dunes—at times spilling over them—along the oceanfront. Neddie Rose Drive in Westport was underwater from the tower to the fisherman’s memorial. The streets department was out blocking roads and clearing debris. Although only a few people were watching today, in recent years, the town has worked to promote king tides as a winter tourism draw. However, the spectacle truly captivates only when paired with a sizable swell like today. While technically the first king tide doesn’t arrive until Friday, the swell forecast for Thursday at 17 feet will be much more impressive than the weekend forecast. The swell picks up again on Monday with 15 foot waves in the forecast.

The Danger of Sneaker Waves and Surges
During king tides, the risks from sneaker waves and surges intensify. The combination of high water levels and large swells can push waves much farther up the shore than usual, submerging rocks, logs, and other hazards. Even experienced beachgoers are urged to keep a safe distance, as the waves can carry with them heavy debris that can cause serious injuries. The Washington State Department of Natural Resources advises maintaining a substantial distance from the water’s edge during these events and always keeping an eye on the ocean, as conditions can change in an instant.

King Tides tell the future
King tides offer coastal communities an opportunity to observe firsthand the effects of rising sea levels. According to the Washington State Department of Ecology, “king tides today will be our everyday high tide in the future.”
Scientists and coastal planners see these tides as valuable data points for understanding future sea-level rise. Local residents are encouraged to help collect that data. My Coast is a tool where anyone can take and upload photos of king tides, marine debris, storm surge, abandoned boats, and more. This data helps map out vulnerable areas and guide future decision-making.
Experiencing the Oceans Power
For locals and visitors alike, witnessing a king tide combined with a big swell is a moment of awe and reflection. The energy is palpable- the excitement is undeniable. It can also be a humbling experience. One that reminds us of nature’s unpredictable power. So get out there and witness the beauty of our backyard, but be safe and watch out for sneaker waves!
