Harbor Entrance at Eureka Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it. The next couple of weeks are looking like a bit of a mixed bag—there’s some size on the way, but we’ve got to deal with onshore winds and tricky conditions for a lot of it. We’re not talking about a clean, classic summer window here, but there are a few moments where it could line up if you’re willing to pick your sessions carefully.

The swell energy is moderate to strong, with values hovering in the 400s to 1000s range, building into the middle of next week before backing off. The water temp is about average for this time of year, so nothing wild there.

Let's start with the immediate picture. The outlook for the next few days is pretty ordinary. We’ve got a mix of cross-onshore winds and a short-period NNW swell that’s going to keep things lumpy and uninviting. Saturday the 8th and Sunday the 9th are looking like write-offs for a decent wave. The swell is there, but the period is short, and the wind is just going to chop it all up. The energy is moderate, but it’s not doing anyone any favors.

Monday the 10th and Tuesday the 11th see the swell building, with energy climbing into the 1000s, but we’re still stuck with short period, onshore conditions. The size is getting up there, but the quality is missing. It’s frustrating, to be honest. The swell is pushing 8ft to 10ft, but with that 8-9 second period and cross-onshore wind, it’s going to be a mess. This is more of a stare-at-it-from-the-sand kind of day than a paddle-out day.

We get a bit of a reprieve on Wednesday the 12th. The swell is still solid at 10ft to 12ft, and the wind swings around to a light cross-shore from the NNE. That’s a big improvement. The energy is strong, hitting 1911 by the afternoon. This is the one standout in the first week. The Harbor Entrance at Eureka is going to be handling a solid, powerful NNW swell. The cross-shore wind will keep it a bit more manageable. It’s still going to be big, over 8ft, so this is for experienced surfers only. This is the best the first week has to offer, and it’s not even close.

After that, the swell starts to ease off. Thursday the 13th is still rideable but the wind turns against us again, and by Friday the 14th, the energy has dropped way down. However, look at Friday afternoon. The wind goes glassy, and the swell settles to a clean 4.5ft from the NW. That’s a beautiful window, clean and glassy, perfect for a longboard or a funboard. It’s a small window, but it’s a good one.

Then we hit a flat spell. Saturday the 15th through Monday the 17th is a dead zone. The swell drops to almost nothing, with energy readings in the low double digits. It’s flat. There’s nothing to do but wait it out. This gap lasts for about three days, so don’t bother checking the cams.

The next pulse of energy shows up Tuesday the 18th. The period jumps up to 13-15 seconds, which is a proper groundswell. The direction is more WNW, which is a better angle for this spot. The size is modest, around 3ft to 5ft, but that long period will give it some push. The wind is still a light cross-onshore, so it’s not perfect, but it’s a step in the right direction.

Wednesday the 19th and Thursday the 20th look like the best of the second week. The swell holds at a fun 4.5ft to 5ft with that WNW groundswell, and we get some glassy windows, especially Wednesday afternoon and Thursday morning. The energy is moderate, in the 400s, and the conditions should be clean. This is your chance to get back out there on a proper wave. It’s not huge, but it’s clean and has some push to it.

The energy fades again after that. Friday the 21st gets a little bump in size but the period drops back to 7 seconds and the wind is on it, so it’s not great. Saturday the 22nd and Sunday the 23rd are similar, with short-period NNW swell and onshore winds. The magic is gone.

So, to wrap it up: the standout sessions are Wednesday the 12th for the big, powerful stuff—if you’ve got the skills—and the glassy windows on Wednesday afternoon and Thursday morning of the 19th and 20th for a cleaner, more user-friendly wave. Everything else is marginal or a flat-out miss. Get on it when the windows open.
