The Lowdown
Alright, Rusty here again, looking at the same charts for North Jetty at Eureka, but in feet and miles per hour for you.
It's a bit of a mixed bag at the start. That exposed jetty spot is taking the full brunt of the wind, so the first few days are more about staying upright than getting a clean barrel.
Monday morning (September 14th) is a no-go. That 6ft NW swell is blown to bits by a cross-onshore. By the afternoon, it's worse: 7ft of NW swell with a moderate breeze. Tuesday (15th) the morning is a bit better with a light breeze, but it's still cross-onshore, meaning a bumpy surface on that 7ft NW swell. The wind stays annoying through the weekend.
The swell dies off sharply on Friday the 18th – down to 2ft from the SW, so you're not going anywhere.
There's a real quiet stretch from the 18th afternoon through to the 21st. The surf is tiny or just not breaking right, with those 18-19 second swells which are real tough for a beach and jetty spot.
The action picks up again on Monday the 21st. The NW swell builds back to 7ft, and while the wind is still cross-onshore, it's just a light breeze. That's a step in the right direction.
The real standout is Tuesday the 22nd. That morning you've got 8ft of NW swell. It's pushing into expert territory for size, but the energy is huge. The best session of the whole run looks like Tuesday afternoon: 7ft from the NNW with only a light breeze – the biggest, most powerful swell with the cleanest wind of any of the bigger days.
After that, the swell eases. Wednesday the 23rd brings 5ft to 6ft from the NW with light, but cross-shore, winds.
Then we hit a glass-off moment. On Friday morning the 25th – about a week and a half out – the conditions turn magic: glassy, with a clean 4ft WNW swell. That's pure, clean fun. The afternoon stays glassy but the swell drops to 3ft.
There's another glassy window on Monday the 28th morning with a 4ft NW swell – perfect for a cruiser. But don't blink, because that afternoon a 30 mph SSW wind kicks up and ruins the party.
Best bets: For power, Tuesday the 22nd afternoon (7ft, light breeze) is the one to circle on your calendar. For the cleanest, most enjoyable waves, Friday the 25th morning (glassy, 4ft) is the session you'll be telling your mates about.
