Black Rocks Jetty Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Right off the bat, the first few days are pretty quiet. Tuesday morning starts with a little 3ft S swell at 11 seconds, but honestly, it’s just surfable, nothing to get excited about. That glassy morning wind from the NNW is about the best part of it. The water’s sitting at a pleasant 76°, which is a touch warmer than normal for this time of year – nice for a long session. Tuesday afternoon stays small with 2ft S swell. Wednesday drops right off with tiny 1ft SW swell and a cross-onshore wind, so that’s a skip. Thursday morning picks up a bit, 2ft SW, still glassy, but we’re just ticking over.

Friday is where things start to get interesting. The morning still looks small (2ft SW), but the swell period jumps to 19 seconds and the combined energy hits 467 – that’s moderate energy, and it’s building. By Friday afternoon, the swell is 5ft SW at 17 seconds, and the energy is ramping up to 1221 (moderate to strong). The wind is cross-on though, so keep an eye on the tide. This is the first real sign of life.

Saturday morning, September 5th, is the first standout of this outlook. We’ve got a clean 5ft SW groundswell at 14 seconds, glassy conditions with a light W wind, and the combined energy is a solid 1016. That’s excellent surf for experienced surfers. The water’s still lovely and warm for the time of year, too. Black Rocks Jetty is a reef break, very consistent, and with that long-period SW groundswell, it’ll handle it well. Crowds are possible here sometimes. Saturday afternoon stays good, dropping to 5ft but still glassy.

Sunday the 6th is mixed. Morning is a bit tricky with a cross-shore wind on the 4ft SW swell – marginal. But Sunday afternoon cleans right up with a cross-offshore N wind at 10 km/h, 4ft SW swell, and clean conditions. That’s a nice session if you can get out.

Monday the 7th turns ugly. Strong onshore SW wind at 15 km/h on a 5ft SSW swell makes for poor conditions, and it gets worse in the afternoon with a 25 km/h southerly cross-onshore. Choppy and messy. Hard pass.

Tuesday September 8th is a big shift, but not for everyone. The morning sees 13ft SSW swell at 12 seconds, but the cross-shore wind and chop make it marginal. The energy is strong at 6055. The afternoon is the real eye-opener – 16ft SSW groundswell with a 20-second period! Combined energy is a massive 18922. That’s very strong. The wind is cross-shore and choppy, but the wave comment says it’s too big for this break. This is expert territory only, and even then, it’s a beast. Beginners, stay far away.

Wednesday the 9th is the real prize for big-wave hunters. Glassy conditions in the morning with a 13ft SSW swell at 17 seconds, energy at 10024, and the report says “exceptional surf conditions for expert surfers.” The afternoon holds with an 12ft SSW on a clean offshore NE breeze. This is the top of the heap – heavy, powerful, and for experts only.

Thursday the 10th settles down but is still excellent – 8ft SSW in the morning, glassy, and again in the afternoon with 7ft. Experienced surfers will have a field day. The water’s still warm.

From the 11th to the 16th, the surf stays manageable and fun, but nothing as epic as that big pulse. Friday the 11th gives a glassy 3ft SSW morning and a bigger 5ft S swell in the afternoon. Saturday the 12th is all glassy with 5ft SSW. Sunday the 13th has a bit of onshore wind in the morning on 8ft, but the afternoon cleans up with a cross-offshore breeze and 10ft SSW – excellent for experienced surfers again.

The final days (14th to 16th) see the swell dropping back to the 4ft to 6ft range. Some mornings are glassy, afternoons get a bit of cross-on wind, but it’s still surfable and clean if you pick your window. Monday the 14th is a bit rough with onshore wind, but Tuesday the 15th and Wednesday the 16th mornings look glassy with 4ft SSW swell.

Best on offer: Without question, Wednesday September 9th for the heavy hitters – glassy, 13ft SSW, long 17-second period, insane energy. For the rest of us, Saturday September 5th morning with 5ft clean SW swell and glassy wind is the pick.

Rusty out.
