North Jetty at Eureka Surf Forecast and Surf Report

Alright, Rusty here, and I’ve got the lowdown on your local stretch.

Honestly, we’re looking at a pretty drawn-out run of disappointing conditions at North Jetty at Eureka. For the next week and a half, the onshore winds just won’t let up, churning up the water and making things messy. There’s a real gap in quality surf here.

Right now, through the end of August and into September, we’ve got northwest wind on the shoulder or straight onshore, with wave heights bouncing around from a knee-high 2ft up to a messy 7ft. The wave energy is moderate—hitting around 200 on Saturday morning, then climbing to 499 by Sunday afternoon—but the wind state is just bad news. The water temp is about normal for the time of year at 57.4°F.

We don’t get a real window until Thursday, September 3rd. Thursday morning looks like the standout window in this whole forecast. It’s glassy—completely calm winds—with a long-period 3ft south-west groundswell (18-second period). The energy is strong (941). That kind of long period will make for proper, lined-up waves at the jetty, but because it’s a beach/jetty setup, those long-period swells can break a bit straight. Still, for a few hours, it’ll be the cleanest surf we see. The wind switches to a moderate cross-onshore in the afternoon and it’s gone.

After that, it’s more of the same onshore rubbish until Wednesday, September 9th. On the 9th, we see a solid 7.2ft north-west swell with a 12-second period and a huge energy reading of 1491. That’s a powerful, expert-only size. The wind is light and onshore in the morning, but if it cleans up for the afternoon (light cross-on), it could be a heavy one for the crew who know what they’re doing. This one is worth keeping an eye on, but it’s a long way out.

The rest of that second week stays marginal, with fading south-west groundswells and persistent light onshore breezes. There’s a little glimmer on the very last day, September 13th afternoon, where it goes glassy with a tiny 1.6ft south-west swell, perfect for a longboard if you’re desperate.

So, to boil it down: your best bet is Thursday, September 3rd morning for the glassy, clean conditions on that long-period south-west groundswell. The other real standout, but only for experienced surfers, is the big north-west swell on Wednesday, September 9th.
