The Lowdown
Alright, Rusty here again. Let’s break this down for the same stretch but in feet and miles per hour, keeping it real.
First off, the water is about 57°F right now at North Jetty at Eureka – right around normal for this time of year. Nothing wild there.
Monday the 27th, we’ve got some swell around 4ft from the SW with a real long 18 second period. That’s proper groundswell with some pull, but the wind is blowing onshore and the surf is only marginal. Wave energy is moderate at 937. Not a day to get your hopes up.
From Tuesday the 28th all the way through to Friday the 1st of August, it’s pretty rough. Swell stays small, mostly under 4ft, and the wind is cross-onshore every session. Energy drops way down – Tuesday morning is only 112. Poor surf conditions, plain and simple.
Saturday the 2nd, the swell picks up but the wind stays messy. By Sunday the 3rd, we’re seeing 10ft from the NNW with an 8 second period, energy at 1165, but it’s choppy with cross-onshore wind. That’s too big for beginners, and even for intermediate surfers it’s gonna be a fight. With that much wind and size on a beach/jetty setup, honestly, the kite surfers might have more fun than us.
The early part of the second week, Monday the 4th through Thursday the 7th, is still mostly poor. Swell sits between 4ft and 8ft but the wind doesn’t let up. Wednesday the 6th morning has 6ft from the NW at 8 seconds and 547 energy, but the call is still marginal. Not worth the drive.
Now, here’s the good part. Saturday the 9th of August morning through to Tuesday the 12th, the swell really lights up. Saturday morning we’ve got 12ft from the NNW with a 10 second period and energy at 2144. That’s big, solid swell. The wind is onshore that morning – could be clean if it stays light. By the afternoon, it’s 8ft from the N with 2213 energy, but cross-onshore. That’s expert-only size.
Sunday the 10th holds similar – 12ft again, 10 second period, energy at 2189 in the morning and 2692 in the afternoon. Wind is still cross-onshore but gentle. These two days, the weekend of the 9th and 10th, are your standout window. If you’re experienced and can handle some chop, that’s your time. Swell direction is NNW, right where this break likes it.
Monday the 11th is still solid at 10ft but the period drops to 9 seconds. Tuesday the 12th sees 8ft from the NW with an 8 second period, and the wind finally turns cross-shore with light breezes. Energy is still strong at 1120-1491, and it’s the cleanest we’ve seen all forecast.
Bottom line: the first week is a wash. Your only real shot is the weekend of the 9th and 10th of August – big swell, strong energy, and if the wind plays nice, it could be something special for the experienced crew. It’s a long way out, so stay tuned.
Rusty.
