The Lowdown
Alright folks, Rusty here. Let’s get into it for North Jetty at Eureka.
We’re looking at a pretty slow start, to be honest. The first few days are a write-off – poor surf and cross-onshore winds are making things messy. Monday the 7th and Tuesday the 8th are a no-go. The swell is weak and short-period, and the wind is just ruining any chance of a clean wave.
Things start to look a little more interesting by Wednesday the 9th. The swell picks up to 5ft from the NNW with a period of 8 seconds, and the combined energy is moderate (436). It’s still cross-onshore, but it might be worth a look if you’re really keen. Thursday morning the 10th is a tease – a 3ft south-west groundswell with a very long 17-second period, giving a moderate energy reading (780), but the wind is onshore. That long period means the sets are gonna be fat and drawn out, but the wind will mess with the surface.
The real standout, the one you’ve been waiting for, is Saturday the 12th. The morning is glassy as glass. We’ve got a 3ft south-west swell with a long 14-second period, and the energy is solid (679). It’s not huge, but the conditions will be *pristine*. The water temp is about 58°F, which is basically normal for this time of year. This is your best bet for a clean, fun session.
After that, it’s back to a bit of a mixed bag. Sunday the 13th and Monday the 14th have some energy (6ft to 7ft) but it’s short-period windswell and the wind is mostly cross-onshore. It’ll be lumpy. The long-range forecast then gets a bit sad – a lot of days with very small surf and onshore winds. The swell from the SW is long-period but weak.
Then, hold onto your board. On the 22nd of September, we’ve got a proper pulse showing up. A 7ft to 8ft swell from the WNW with a 14-second period is pumping in, and the combined energy is strong at 2143. That’s a lot of water moving. The wind is light and cross-onshore, which is a big deal. This is a serious swell for experts only – over 8ft is pushing it for most, but this one is right on the edge. It’s a long way out, so don’t book the time off just yet, but keep an eye on it.
For the most part, the setup here is a beach/jetty, so when the swell is big and the wind is on, it’ll be a mess. On Saturday the 12th, it’s going to be a dream for the intermediates. For the big one on the 22nd, it’s all about the experts.
Rusty.
