The Lowdown

Alright, Rusty here. Let's take a look at what we've got cooking. It's been quiet, but we've got a solid run of surf on the horizon.

The pattern is setting up for a drawn-out run of clean, consistent SW groundswell at Black Rocks Jetty. It's not going to be massive, but it'll be persistent. The water temp feels about average for this time of year.

We kick off on Wednesday morning. It's small, clean and glassy with a 2ft SW swell and a long 15-second period. The combined energy is moderate (298). Not a standout, but a nice way to start. The morning glass will be your friend here.

Thursday and Friday are a bit mixed. The swell holds around 3ft to 3ft with moderate energy, but the wind and tide look a bit iffy at times. Friday morning, however, is dead calm and glassy with that 3ft SW groundswell. It’s the pick of the early days.

Then we get to the real meat. From Saturday the 8th of August through to Tuesday the 11th, we see a noticeable uptick. The swell jumps to 4ft to 4ft from the SW, with periods around 14 to 18 seconds. The combined energy readings are solid, sitting between 635 and 810 (moderate energy). The standout here is Saturday morning: glassy conditions, 4ft of clean SW groundswell at 18 seconds. It’s not huge, but the quality is going to be excellent. Crowds are possible here, so get in early.

The second week builds on this. Wednesday the 12th morning is a gem with 5ft SW swell, dead calm, and glassy conditions. Combined energy is strong at 825 (moderate). But the real highlight of the whole outlook is the following Saturday and Sunday, the 15th and 16th of August. We’ve got a stronger pulse of SSW swell, with the morning of the 15th showing 5ft at 18 seconds and glassy conditions. Combined energy is very strong (2158). Saturday afternoon jumps to 6ft and Sunday morning hits 7ft. That’s expert territory. Both days are glassy or near glassy, with light winds. This is the standout window for experienced surfers. The period is long (16-18 seconds), so expect well-shaped waves at this reef, with longer lulls between sets. The energy is there, the quality is there.

The swell tapers off through Monday the 17th and Tuesday the 18th, with waves dropping from 5ft down to 4ft, still clean. The final days of the outlook, the 19th and 20th, are small but clean, with 2ft to 2ft.

So, to wrap it up: the best on offer is the Saturday the 15th and Sunday the 16th of August for the bigger, cleaner swell. If you want something a bit more manageable, the morning sessions from the 8th through the 12th are your best bet. Stay safe out there.
