Corona Del Mar Jetty Surf Forecast and Surf Report

Alright, let’s get into it.

The long-range picture here starts with a solid pulse of southwest groundswell, but it’s a short-lived window. We’ve got the most size and energy on Monday the 7th, and that’s where the good stuff is. After that, it fades fast and we’re looking at a whole lot of nothing for days. We’re talking about a significant lull from roughly mid-week through the following week. There are hints of a small push way out near the 21st, but that’s a long way off and not something to get too worked up about yet.

Monday morning, September 7th is the standout. Corona Del Mar Jetty is where you want to be. It’s a breakwater setup, fairly exposed to the SSW swell, and that’s exactly what’s coming. We’re looking at surf around 5ft from the SSW, with a solid 13-second period. That’s proper groundswell, and it’s got some punch. The energy reading is 950, which is a solid, moderate-to-strong push. The wind is light and offshore from the WNW at 6 mph, so it’s going to be clean, glassy, and lined up. This is the pick of the whole forecast, no question. It’s not huge, but it’s quality. The water is at 73°F, which is a notable 6°F warmer than average for this time of year – that’s significantly warm, so the wetsuit can be a thin one or maybe even a springy. The spot is often crowded, so expect some company, but the clean conditions will be worth it. This is more of an intermediate zone, so if you’re just starting out, this size is manageable but with that period, it might be pushing it a touch.

Monday afternoon sees the same 5ft SSW swell but the wind picks up to a 12 mph WNW cross-offshore. It’s still clean, but that bump in wind makes it a bit less perfect than the morning glass. The energy drops a bit to 752. It’s still good, just not as good.

From Tuesday the 8th, it’s a quick downward slide. The swell drops to under 3 feet, the period drops, and the energy levels fall off. Tuesday morning is 3ft from the SSW with a 10-second period and a cross-shore wind, making it small and a bit crumbly. From Tuesday afternoon through the 13th, the size keeps dropping, and the winds start turning onshore from the south and southeast. It’s small, weak, and messy. The energy readings are all in the low hundreds, which is just weak. There’s nothing rideable here, honestly.

The period from the 10th through the 13th is a dead zone. South winds, tiny waves, all poor conditions. It’s a beach and breakwater setup, so with the onshores and small swell, it’s not even going to be fun to sit out there. This stretch might hold more interest for the kite crew than us paddle surfers, to be honest.

There’s a flicker of life on the 16th and 17th with some 2-3ft SSW swell and a longer period of 17-18 seconds, but the winds are mostly cross or light onshore. It’s marginal at best; you’d be scratching for anything. That long period might make it break a little straight at the Jetty, so it’s a caveat.

The next possible window is around Monday the 21st and Tuesday the 22nd, where we see a bit of a bump back up to 3ft from the SW with a decent 17-18 second period. The energy is back up to the 500-560 range, which is moderate. The winds are light, but the direction is a bit iffy. It’s promising, but it’s a week and a half away, so treat it as a “maybe” rather than a certainty.

So, to sum it up: hit it hard on Monday the 7th. That’s your window. After that, it’s a long, flat, blown-out stretch for the most part. The only other faint glimmer of hope is way out there near the 21st, but don't hold your breath on that one.

Rusty.
