The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for the next couple of weeks. It's gonna be a bit of a mixed bag, so let's break it down.
Right now, we've got a slow start. The first real chance of a surf is on Sunday the 13th, but it's not much to write home about. North Jetty at Eureka is seeing a 5ft WNW swell with a short 8-second period, and a cross-on wind is making it messy. The water temp is 58°F, which is pretty much bang on average for this time of year, so no surprises there. The energy reading is 528 (moderate), but the quality is just not there. That pattern keeps going for days with a steady increase in swell size, hitting around 7ft by Monday afternoon, but that cross-onshore wind stays persistent, chopping things up. Honestly, this stretch from the 13th through to the 16th is a write-off for decent surf.
We finally get a slight shift around Wednesday morning the 16th, with the wind turning straight onshore but still light, and swell around 7ft. Still not great, but at least it's not side-shore chop. The energy stays moderate, but the wave comment tells me it's marginal at best.
Moving into the second week, things start looking a bit more promising. On Tuesday the 22nd, we've got a 8ft NW swell with a 8-second period. The energy jumps to 1266 (strong), and with light cross-onshore winds, it might just be worth a paddle. But the real standout is the 23rd of September. Wednesday brings a 8ft NW groundswell with a solid 13-second period, and the energy reading is a massive 2279 (very strong). The wind is light cross-onshore, which is decent, but for a jetty break, that long period can make waves a bit walled. Still, if you're an experienced surfer, this is the one to circle on your calendar.
Towards the end of the run, we see another pulse on Friday the 25th with a 8ft NW swell and 10-second period, energy at 1126, but again, the wind's not cooperating. Saturday the 26th has a 8ft NW swell with 9-second period, but it's blown out by the afternoon.
So overall, the first week is a bust. The second week has a couple of moments, but nothing that's gonna have you ringing in sick. The best bet is the 23rd, that big groundswell with good energy, but keep in mind it's a long-period swell at a jetty, so it might not be the perfect wave. Stay tuned, things can change.
