(Seaside, Oregon) – King Tides don't necessarily mean large wave action – but this week's run of the first set for the year is likely to be lively. If they combine with incoming storms, then you've got the recipe for sizable surf (and dangerous, too). From the south Washington coast all the way down through Brookings, there are high wind warnings, flooding advisories and some massive wave height coming together and at different times.

What's the Difference Between King Tides and Oregon / Washington Coast Storm Wave Events?
Today, much of the coastline is at the tail end of advisories for sneaker waves, but more heavy surf is on its way, coinciding with the king tides that start Wednesday.
At the very least, the south Oregon coast is going to see large and very dangerous waves, but the big show could happening up north, though it's not yet certain.
What's coming up:
A High Wind Warning is in effect Monday for much of the southern Oregon coast, extending from Brookings northward past Coos Bay, according to the National Weather Service (NWS). South winds of 35 to 45 mph are forecast, with gusts reaching up to 60 mph along exposed areas including capes and headlands. Impacted locations include Cape Blanco, Cape Arago, Humbug Mountain, Bandon Head, Pistol River, and vulnerable stretches of Highway 101 within Coos and Curry counties.

Hazardous beach conditions are anticipated Thursday as a strong storm system brings a long-period west swell to the south coast. The NWS expects breaking waves between 23 and 26 feet, with high surf conditions potentially intensified by seasonal King tides, meaning Shore Acres will likely be impressive again.

However, low-lying streets prone to tidal impacts may experience flooding, and officials caution drivers to avoid flooded roadways.
“Never drive through flooded waters,” the NWS said.
Farther north, a Coastal Flood Advisory is in place for Wednesday from 10 a.m. to 2 p.m. along the South Washington Coast and the Clatsop and Tillamook County coasts. Minor tidal overflow flooding - up to one foot above ground level - is expected in low-lying areas near bays, sloughs, and the lower reaches of coastal rivers. Portions of Highway 101 near Raymond, Seaside, and Fraser Road in Tillamook County may be affected. Residents are urged to monitor conditions and avoid floodwaters due to safety risks.

The upper half of Oregon and the lower portion of Washington's coast may also see large wave action with the king tides, but it's not yet certain.
Seas are currently forecast to rise into the mid to upper teens by Wednesday, driven primarily by wind. But it could get wilder.
“Guidance currently suggests a 5-10% chance that seas will exceed 20 ft.,” the NWS said. “There is still plenty of uncertainty in exact details but the active pattern is expected to persist.”
Stay off all beaches during these alerts. Sneaker waves already took one life this season.
