The Lowdown
Alright, Rusty here with the yardstick version. Let’s break down North Jetty at Eureka.
The first few days are a wash. We’re looking at choppy, cross-onshore wind and small swell. The water is 54°, which is a touch colder than usual for this time of year. Wednesday the 15th and Thursday the 16th? Forget it, the surf is poor.
Friday the 17th shows a little life. The morning brings a 3ft swell from the WNW with a 17-second period. That’s a long-period groundswell, and the wind is offshore. The energy is moderate (1014), so it’s worth a look. Saturday the 18th morning bumps up to 7ft from the NW with a light offshore, but the period drops to 8 seconds. It’ll be a bit short and dumpy.
The real standout is Sunday the 19th. The morning session has 7ft of NW swell, and the wind is light and offshore. It’s going to be glassy and clean. The energy is solid (1111). The afternoon also holds clean with 7ft and offshore winds. This is the best window.
Monday the 20th is still okay with 6ft from the NNW and light offshore winds in the afternoon, but the energy is lower (882). Then we hit a real gap. Tuesday the 21st through Thursday the 24th is mostly poor or marginal with cross-onshore winds and small, weak swell. Not worth paddling out.
Friday the 24th afternoon has a weird one: 3ft from the SW with a 24-second period. That’s a super long-period groundswell, and at a beach/jetty, it might just break too straight. Still, the energy is healthy (1063). Saturday the 25th is similar, with long-period SW groundswell, but again, tricky for the spot.
The final push is Sunday the 26th and Monday the 27th. We’re looking at 8ft from the NNW with a 9-second period on Sunday morning. That’s big – expert-only territory. The wind is light cross-onshore, so it’ll be a bit lumpy. The energy is very strong (1020). It’s a big, short-period swell, so expect it to be fat and dumpy.
So, the call is: Sunday the 19th is your best bet for clean, glassy waves around 7ft. The long-range stuff is a maybe, but don’t get your hopes up too high.
Rusty.
