Corona Del Mar Jetty Surf Forecast and Surf Report

Alright folks, this is Rusty, checkin’ in from the beach. I’ve got the long-range picture for Corona Del Mar Jetty, and I gotta be straight with you—we’re in for a lean spell. There’s no real green light for a proper paddle for almost a whole week, so don’t be holding your breath for a session today or tomorrow.

Right now, the Jetty is stuck with a long-period SSW groundswell running around 3ft, but the wind is howling onshore straight out of the south at 15 km/h, which is just trashing the surface. It’s a mess out there. That 15-second period gives it a bit of hump, but combined swell energy is sitting at a moderate 533, and with that wind it’s just not worth the effort. This grim pattern sticks with us through the whole first week of September; every day is either cross-on or cross-shore breezes, keeping the wave face bumpy or blown out. You’ll see swell heights dropping to those tiny 2ft days with weak energy numbers in the 200s to low 300s–it’s a total flat spell in disguise.

Now, let’s look at a glimmer of hope. Come Saturday, the 5th of September, the afternoon shows a marginal chance with a 3ft SSW swell and a 16-second period pushing combined energy up to 685. The wind is a gentle cross-shore at 15 km/h, so it’s still got a bit of chop, but it’s the best we’ve seen in days. Not clean enough to rave about, but keep an eye on it.

The real standout, the one you’ve been waiting for, is the Sunday morning of the 6th. This is the best on offer across the whole outlook. We get a 3ft S swell, solid 13-second period, and a beautiful light NNE breeze at 10 km/h coming across-offshore. The forecast says ‘clean’ and ‘expect very good surf conditions’ – that’s the ticket. The combined swell energy climbs to a healthy 676, so there’s a decent push behind those lines. It’s not gigantic, but for a jetty that can be a bit fickle, this is a proper window for a clean, fun session. The water temperature is about average for this time of year.

After that high, Monday the 7th has a reasonable 4ft S swell in the morning with a glassy 5 km/h onshore breeze, but it’s still rated as marginal. Then we hit a rough patch mid-week with the swell bumping up to 5ft on Tuesday the 8th and 9th, but the period drops way off to 10 seconds or less – short period, weak energy for the height, and the wind is messy. That bigger swell is mostly for the experienced crew if they want to battle the chop; for the rest, it’s a pass.

The second week fades out fast. From the 10th of September onward, we’re back to tiny 2ft to 1ft swells with very long periods (15-19 seconds) that just don’t have the grunt for this spot, and the combined energy numbers drop into the low 200s. Pretty much a write-off for a decent paddle.

So to wrap it up: don’t bother this first week except for that Sunday the 6th morning. That’s your window. It’s a clean, light-wind morning with a solid waist-high groundswell – keep your schedule clear for that one.

Rusty.
