Black Rocks Jetty Surf Forecast and Surf Report

Alright, grab your wettie and let’s talk about the next couple of weeks. It’s a mix of chaos and clean windows, but you gotta know when to paddle out.

We kick off Thursday the 27th of August at Black Rocks Jetty with a solid SSW groundswell pushing 10 feet and a very long 17-second period. The water is 77°, which is much warmer than usual for this time of year – a real bonus. The morning is clear with a light 5 mph SSW wind, but it’s cross-on, so the face has a little texture. The combined energy is massive at 4932, so there’s plenty of grunt, but the tide could mess with the shape. This is advanced territory only. By afternoon, the wind jumps to 20 mph, making it choppy and messy – stay out.

Friday the 28th gets worse. Rain showers, 30 mph winds, and the swell hits 13 feet with 16-second periods. The energy is pumping at 7980 to 8605, but the wind is cross-on or cross, making it lumpy and borderline unsurfable. Hard pass.

Now, Saturday the 29th is where it gets good. The swell drops to 12 feet but still carries a long 15-second period. The magic is in the wind – glassy conditions, 5 mph from the ESE in the morning and E in the afternoon. This is excellent surf for experienced surfers, with clean, powerful lines rolling through. The energy is still strong at 4900, but the lack of wind makes it properly rideable. The SSW swell direction lines up nicely with the optimum SW direction for this reef. If you’re advanced, this is your window.

Sunday the 30th morning keeps the glassy conditions with a 7-foot SSW swell at 14 seconds. Energy is down to 1969, but it’s still solid. The wind is light from the SSW, glassy again. This is good for experienced surfers, but the swell is dropping. By afternoon, the wind switches to 10 mph cross-on, and the quality fades.

Monday the 31st and Tuesday the 1st see the swell drop off hard. We’re down to 4 feet and 3 feet, with short 11-12 second periods. The energy is weak (149-497), and conditions are ordinary. There’s a stretch of days with very little to offer.

From Wednesday the 2nd through Friday the 4th of September, it’s flat. Waves are tiny – 1 feet to 2 feet. The energy is below 100. It’s mostly glassy, but there’s nothing to ride. This is a real lull.

But hold on – Saturday the 5th of September brings a new lease of life. The swell kicks back up to 4 feet with a 15-second period from the SW. The wind is glassy, and the energy is moderate at 648-685. This is “expect very good surf conditions” – clean, lined up, and perfect for a fun session. This continues into Sunday the 6th with similar conditions and a cross-off wind in the afternoon keeping it clean.

Monday the 7th of September looks promising too. The morning sees a 4-foot SW swell with 14-second period, and a moderate offshore NNE wind at 20 mph. The energy is 809, and it’s clean. The afternoon wind picks up to 25 mph cross-off, but the swell builds to 5 feet. This is a good run for experienced surfers.

Then Tuesday the 8th and Wednesday the 9th bring a big, messy swell. We’re back to 10 feet with 12-13 second periods, but the wind is onshore and strong. The energy is huge (2794-5931), but the conditions are choppy and lumpy. This is for kite surfers, not paddle surfers.

Thursday the 10th and Friday the 11th of September taper off, with the swell dropping to 5 feet, but the wind stays cross-on or onshore. The energy is still moderate to strong, but the quality is marginal.

If you’re looking for the standout, it’s Saturday the 29th of August – glassy, 12-foot SSW groundswell, proper energy, and clean. That’s the one to circle. The second week has some promise on the 5th and 6th of September, but it’s not as solid.
