Black Rocks Jetty Surf Forecast and Surf Report

Alright, Rusty here, let's talk about what's coming up at Black Rocks Jetty. This is a reef setup, so it's one for the advanced crew. The water temp is sitting pretty much average for the time of year, nothing wild there.

We've got a bit of a slow start this morning, September 13th. There's some solid energy in the water—a very strong 1820 combined energy—with a 5ft SSW swell pushing through, but the wind is on it and the tide feels a bit off, so it's not firing on all cylinders. It'll be a bit of a struggle this morning. By the afternoon, a touch more size at 6ft from the same SSW direction, but the wind goes cross-on, so it's looking messy with that 1857 combined energy. Not the best way to kick things off.

Now, Monday morning, September 14th, is a real treat. The wind drops to glassy, pure glass, and the sea goes slick. We've got a 5ft SW groundswell at a 14-second period. The combined energy is still a solid 918, so it's got some push, but that glassy surface will make it look like a mirror. This is the standout of the early part of the week. It's a proper session for those who are willing to work for it on the reef.

The real highlight, though, is the Tuesday the 15th window. Tuesday morning is clean with a light cross-off breeze and a 5ft SW swell that's got an 18-second period. The combined energy is a whopping 2124—that's strong, powerful water. Those long-period lines will wrap in nicely, and the wind is perfect. Tuesday afternoon is even better: glassy flat calm with a 6ft SSW swell and a massive 2575 combined energy. This is the best on offer, no question. For experienced surfers, this is the session to circle.

We get a bit of a lull from Wednesday the 16th through the end of that week. Wednesday morning sees the swell jumping to 8ft from the SSW, but with onshore wind, it's going to be a beast. That's heavy-duty, expert-only territory. Wednesday afternoon cleans up to glassy with a 8ft SSW swell at 14 seconds, and the combined energy is still a very strong 2197. Good for the brave. Thursday and Friday drop off in size, with clean glassy conditions on Thursday and Friday mornings, but the swell gets smaller and the period drops. The energy is moderate—878 on Thursday morning, down to 248 on Friday morning. It's not a complete write-off, but it's small and weak.

We hit a real flat spell from Saturday the 19th through most of the following Tuesday the 22nd. Swell drops to under 3ft, with combined energy barely breaking 300 most of the time. It's mostly blown out or weak. There's a tiny window on Sunday afternoon the 20th where it goes glassy with a 3ft SW swell, but don't get your hopes up. It's a full four-day gap with nothing worthwhile.

Things start to build again later in the week. Wednesday the 23rd and Thursday the 24th are building back up, but the winds are mostly on or cross-on, so it's marginal. The real return to form comes on Thursday afternoon the 24th. It goes glassy flat calm, and the swell jumps to 4ft from the SSW with a 14-second period and a combined energy of 1062. That's moderate but clean. Then Friday morning, September 25th, is the true standout of the second week. We get a glassy morning with a 6ft SSW swell pumping in at a 16-second period, and the combined energy hits 1418. The water will be lined up and the wind will be off. That morning is the one to aim for.

We end the lookahead with some big stuff on Monday, September 28th. The forecast shows a glassy morning with an 8ft SSW swell at a 15-second period and a very strong combined energy of 2806. That is a serious, expert-only day. The waves will be powerful and thick. If you've got the skills, that's a day to be in the water.

So, to sum it up: the absolute standout is Tuesday the 15th, especially the afternoon glass-off. Your second-best bet is Friday morning, September 25th. The rest has some ok sessions, but those are your golden windows. Stay sharp.

Rusty.
