Black Rocks Jetty Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s talk about the next stretch at Black Rocks Jetty. We’ve got a slow start, but once the swell gets its act together, this place has a run of good sessions lined up.

The water temp is sitting about average for this time of year, so nothing wild there.

We kick off on Friday morning, August 7th, with a small 3ft southwest swell, but the wind is glassy and the energy is moderate (250). It’s clean and rideable, but nothing to write home about. This is the first surf on offer, but it’s a gentle start.

Friday afternoon drops off fast into tiny 1ft, so don’t bother.

Saturday the 8th sees a bit more life. The morning is a bit messy with cross-on wind, but the afternoon is where it’s at – glassy conditions and a clean 4ft southwest swell with moderate energy (866). That’s a solid session for the weekend.

Sunday the 9th is a bit of a mixed bag. Morning has onshore wind, but the afternoon goes glassy again with a consistent 4ft southwest swell (705 energy). Clean waves, good for a paddle.

Monday the 10th through to Thursday the 13th is a real sweet spot. The swell holds steady around 4ft from the southwest, periods in the 13-16 second range, so it’s groundswell with proper shape. Wind is mostly glassy or cross-off, which means clean surfaces. The energy sits in the moderate range (588 to 939). These are the kind of days where you don’t even check the forecast – you just go.

Now, the standout for the whole outlook is Saturday the 15th. The morning brings a 5ft southwest swell with a long 20-second period, and the energy is strong (1962). The wind is cross-off and clean. For experienced surfers, this is the best of the run. The swell is solid, the period is long, and the break is a reef, so that long-period groundswell will wrap in nicely. Keep in mind, that long period can make beach breaks a bit wonky, but on a reef set-up like Black Rocks Jetty, it’s a dream. Crowds are *sometimes* an issue here, so expect a few others out.

Sunday the 16th brings a bigger push – 8ft southwest swell in the morning, but it’s cross-shore wind and the energy is very strong (3399). That’s expert territory, especially with the size and the wind. The afternoon cleans up with glassy conditions and 7ft, but it’s still big. Only for the experienced crew.

Monday the 17th morning is still pumping with 5ft and glassy conditions, energy strong (1530). A solid session for the advanced surfer.

After that, the swell tails off. The last week of the forecast sees a drop to 3ft to 3ft, with clean conditions but weak energy (under 500). It’s small, mellow, and fun for a longboard or a foiler, but nothing to get fired up about.

There’s a gap from the 22nd onward with no real quality on offer, so if you want the good stuff, aim for the 8th through the 17th, with Saturday the 15th as the absolute highlight.

Rusty.
