The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming down the pipe for the North Jetty at Eureka.
Right off the bat, we’ve got a bit of a slow start. The first few days are a struggle. Wednesday the 5th and Thursday the 6th are offering up small, weak swell around 3 ft to 5 ft from the NW, but the wind is a problem. It’s either cross or cross-onshore, and the wave comment is calling it marginal at best. The combined energy is weak to moderate (426 dropping to 235), and the period is a short 8 seconds, so it’s just not doing much. You’d be fighting for nothing out there.
The real story starts to build from Saturday the 8th. The swell starts to push up, and by Sunday the 9th, we’re seeing a solid 10 ft swell from the NNW. The combined energy jumps into the strong range (1060 to 1164), and the period stretches to 8-9 seconds. This is where it gets interesting. The problem is the wind. It’s cross-onshore from the NNW and N, creating a fair bit of chop. The wave comment still says “marginal,” but for a wave hungry surfer, that’s a lot of water moving.
This swell hangs around through Monday the 10th, Tuesday the 11th, and Wednesday the 12th, with heights staying at that 8 ft to 10 ft mark. The energy is high (over 1000 through much of it), and the period bumps up to 9 seconds, which gives the waves a bit more shape. Honestly, the wind is the only thing holding this back from being a classic. If you’re an expert, this is still your window. The morning of Wednesday the 12th looks the best of the bunch, with a lighter wind state, but it’s still onshore. This is heavy, powerful swell, and the jetty setup will be handling a lot of water. It’s not for beginners—over 8 ft is expert territory.
After the 12th, it doesn’t really drop off, but it settles into a more manageable 7 ft to 8 ft range through the rest of the period. The wind stays a mixed bag, mostly cross-onshore, with a few mornings offering a lighter breeze. The period holds at 8-9 seconds, so the quality is average. The standouts? The morning of Thursday the 13th and the afternoon of Friday the 14th look the most promising with lighter winds and a touch less energy. The afternoon of the 14th has a 5 km/h wind, which is close to glassy—that’s your best bet for a clean, fun session.
Overall, the best on offer is the window from Sunday the 9th through Wednesday the 12th if you’re experienced and don’t mind a lumpy ocean. The real hidden gem is the afternoon of Friday the 14th, with the lightest winds and a 7 ft swell that will be far more user-friendly.
No crowds data is supplied for this spot, so I can’t tell you if you’ll be alone or not. Water temp is about average for the time of year.
Rusty, signing off.
