Alright folks, Rusty here with a look at what’s on the cards for North Jetty at Eureka over the next couple of weeks.
Right off the bat, I’ll be straight with you – for the first few days, it’s pretty grim. We’ve got a run of poor conditions through Wednesday afternoon, all of Thursday, and into the weekend. The wind’s mostly cross-onshore and the wave quality just isn’t there for a paddle. The water temp is sitting at 53°, which is a bit colder than average for this time of year, so you’ll want a good thick suit and booties if you’re even thinking about it.
Wednesday, 8 July sees a 5 ft NW swell but it’s onshore wind and the energy is weak (233). Thursday, 9 July, actually picks up some size – a 7 ft NW swell with moderate energy (530 in the morning, ramping up to 1009 in the arvo) – but the onshore and cross-onshore breeze messes it up. Friday, 10 July, drops right down to 3 ft, though that is a very long-period 15-second groundswell from the SW which can offer beautiful shape, but with those cross-onshore winds, it’s hard to get excited.
The first real glimmer of something comes on Wednesday, 15 July – still a mixed bag with a 3 ft WNW swell and moderate energy (522), but the wind is cleaner than what we’ve been dealing with. Honestly, it’s still marginal.
Now, if you’ve got some patience and you’re an experienced surfer, hold tight for the second week. Starting Thursday, 16 July, things get serious. We’ve got a 8 ft NW swell coming in with strong energy (1066) and a morning offshore wind from the NNW at 9 mph. That’s the kind of combination that could make North Jetty light up before the wind swings cross-on in the afternoon. Conditions are marginal, but that’s where the quality could be hiding.
The standout window looks to be Monday, 20 July morning. The forecast is showing a 10 ft NNW swell with very strong energy (1716) and a light offshore breeze from the NNW at 6 mph. That is proper size – expert territory – and if the wind holds, it could be absolutely firing. The swell period is 9 seconds, so it’ll have a bit of push to it. This one is a promising, long-range call, so keep an eye on it.
After that, Tuesday, 21 July still has some good leftover energy with a 8 ft NNW and light offshore wind in the morning. Wednesday, 22 July offers a 7 ft NNW swell with light wind again – only cross-on that day, but very light at 3 mph.
All in all, there are a handful of decent days in the second week for the brave. But the absolute best bet? Lock in Monday, 20 July for the biggest, cleanest conditions we’re likely to see.
Stay salty,
Rusty
