Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s coming up for Black Rocks Jetty.

We’ve got a solid run of surf ahead, starting right now on Saturday morning. The water is sitting at a touch warmer than normal for this time of year, around 77°, which is a nice little bonus. The opening session is glassy calm with a clean 5ft SW groundswell at 14 seconds, and the combined energy is already pumping at 901 (moderate). That’s a beautiful start to the weekend. Saturday afternoon stays glassy, same size, just a slight shift in period.

Sunday the 23rd is a step up – morning brings 8ft of SW groundswell, glassy as anything, and the energy jumps to 2155 (strong). This is solid, powerful surf for experienced surfers. The afternoon holds at 7ft, still glassy. Monday the 24th is the real standout of this first week: 7 to 8ft, SSW groundswell, with a period nudging 15 seconds, and the morning energy hits 2368 (strong). Offshore wind, clean, glassy – this is the best on offer for the first week. The long period means these waves will have plenty of punch, and at a reef break like Black Rocks, that’s going to produce some proper lines. Just be aware, with that size and power, it’s for the experienced crew only.

Tuesday the 25th drops back a touch to 5ft SSW, still glassy, still very good. Wednesday the 26th is a mixed bag: morning is 4ft and glassy, but the afternoon brings a 3ft SW swell with a very long 18-second period and energy at 1141 (moderate). That long period at a reef break means the sets will be well-spaced and the waves will stand up nicely.

Now, Thursday the 27th things get gnarly. The swell jumps to 8ft SSW, then 10ft in the afternoon, but the wind swings onshore and cross-onshore, getting choppy. The energy is massive (4438 to 5261, very strong), but the quality drops. Friday the 28th is a write-off for paddle surfing – 13ft SSW with 25 km/h cross-onshore winds and energy over 9000 (very strong). That is a kite-surfing setup, not a paddle one. Leave the board at home.

Saturday the 29th is a redemption lap. Morning is 12ft SSW, glassy calm, with energy at 6432 (very strong). That’s an exceptional window for expert surfers – big, clean, powerful. The afternoon drops to 10ft, still clean. Sunday the 30th is back to 8ft and glassy, a solid day.

Monday the 31st sees the swell fade to 4ft, and by Tuesday the 1st of September it’s down to 3ft. The next few days are small, with a few marginal windows. Wednesday the 2nd is tiny, mostly under 2ft. Thursday the 3rd afternoon picks up to 4ft SW with a 16-second period, clean, and that’s a decent little session. Friday the 4th is 5ft SW, glassy in the morning, very good. Saturday the 5th is a bit of a mess with onshore wind, but Sunday the 6th morning is 3ft SW, glassy, and clean.

Best on offer: Monday the 24th (7-8ft, SSW, 15s, glassy, energy 2368) and Saturday the 29th morning (12ft, SSW, glassy, energy 6432). The Monday is a more manageable size for experienced surfers, while the Saturday is a big-wave day for the experts only.

Rusty out.
