North Jetty at Eureka Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s look at the upcoming window for North Jetty at Eureka. It’s a bit of a mixed bag, with a long stretch of small, crumbly days before things eventually get big and burly later on. The water temp is about average for the time of year, nothing unusual there.

We start up on Friday, July 24th. Morning shows a small 2 ft south-west swell with a super long 24-second period. The combined energy is weak at 470, and the morning has some clouds with a light onshore breeze from the north-west. It's really just a marginal call, and honestly, not worth getting excited about. By the afternoon, the swell bumps up to 3 ft from the south-west, still with that long 24-second period, and the energy jumps to 1097. The wind goes light from the north-northwest, almost glassy. It's still on the small side, but a clean long-period south-west swell at a jetty can produce some nice lines when the tide is right. It’s a low-percentage play, but the best shot this weekend.

Saturday the 25th sees a similar trend. A clean morning with a 4 ft south-west swell and a 21-second period, but the wind is a light cross-on from the west, putting a little texture on the face. The energy is strong at 1269. Unfortunately, the forecast says it’s marginal. By Sunday the 26th, we’ve got a 4 ft south-west swell with 19-second period and a cross-on breeze, still giving the wave a bit of bump. The afternoon gets choppier with a north wind picking up.

Then we hit a big slump. From Monday the 27th all the way through the start of August, it’s mostly poor. The swell goes tiny and weak, periods drop right off, and the wind stays cross-onshore. The combined energy readings stay well under 200, just small, weak, and messy. There are a few days with 3 ft to 4 ft of short-period south-west swell, but the wind and overall quality just aren't there. Crowds at North Jetty are a sometimes thing, but with this quality, it’ll be quiet.

The pattern finally changes heading into the second week. Sunday, August 2nd, the swell starts to build. By the morning we have a 8 ft north-west swell with an 8-second period, and the energy jumps to 1038. That’s a solid, powerful, short-period swell, but it’s cross-on and a bit choppy. This is getting into expert territory at 8 ft. The afternoon jumps even more to a proper 13 ft north-northwest swell, with a huge energy reading of 2624. This is very strong, serious power. The wind is a moderate cross-on from the north-northwest, so it’ll be a bumpy, challenging day.

Monday, August 3rd, the swell remains solid at 10 ft from the north-northwest, 9-second period, and 1612 energy. The morning wind is light and onshore from the north-northwest, which is actually quite clean for that size. This is the standout window for the entire outlook. The swell is big (10 ft) and the wind is light and onshore – basically as clean as it gets for a wave that size. This is a day for experienced surfers only. The short period and beach/jetty setup mean it won't have a ton of shape, and it could be a little straight, but the power will be there.

After that, the swell slowly backs off through the week, dropping from 7 ft on Tuesday back to 6 ft by Saturday the 8th, but the wind stays moderate to fresh cross-on, and the period stays short, keeping it messy and poor.

So, the honest truth: the first week-plus is not worth your time. The real action is that Monday, August 3rd, when a big 10 ft north-northwest swell meets clean, light winds. That’s the one to circle on the calendar. For the rest of it, you’re either looking at small marginal surf or big, wind-affected waves.

Rusty.
