Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here with a look at what we've got cooking. We're going straight to Black Rocks Jetty for the next couple of weeks, and there's some serious gear on the way.

Right off the bat, Wednesday the 19th serves up a gentle start. We're looking at a small 3ft swell from the south, but with glassy conditions and a slight air, it’s perfect for a longboard or a funboard. The water's sitting at a nice 77°, and that's about two degrees warmer than we'd normally expect for late August. That's a real treat.

Thursday keeps the same vibe – small but clean. Then Friday morning the 21st gets interesting. The swell bumps up to 4ft from the southwest, with a 14-second period, and it's dead calm. The combined energy is moderate at 611, and the potential is there for some genuinely fun, lined-up waves. This is a solid option for the intermediate surfer. By Friday afternoon the wind gets a little cross-on, so hit the morning session.

Saturday the 22nd is where it starts to get chunky. Swell hits 5ft from the southwest, energy climbs into the strong range (901), and Saturday afternoon goes glassy. This is when the reef starts to really show its shape. Sunday the 23rd is a standout for the experienced crew: 8ft of SW groundswell with a 14-second interval, and a combined energy of 2155. With zero wind forecast for the afternoon, you're looking at clean, powerful, and very well-defined waves. It's a touch heavy for beginners, but for anyone with a bit of experience, it's the pick of the first week.

Monday the 24th continues the trend with 8ft from the SSW, but the afternoon gets a cross-shore wind, so make it a morning mission again.

The middle of the week (25th-26th) calms down a bit, with some decent morning glass on Tuesday the 25th (6ft), but Wednesday the 26th gets a bit onshore and messy.

Now, for the long-range call: Thursday the 27th and Friday the 28th. This is the big one. Thursday the 27th sees a massive 13ft SSW swell rolling in with a very long 18-second period. Energy is extreme at 9725. It's a huge, powerful groundswell, but with a cross-shore wind, it’ll be tricky. The real prize is Friday the 28th morning. The swell is still a solid 12ft from the SSW, period at 16 seconds, but the wind goes completely glassy. The energy is still massive at 7043. This is a full-on, expert-only session. It will be a raw, heavy, world-class reef break. If you're a pro, this is it. For anyone else, maybe just watch from the headland.

After that, the swell backs down through the weekend and into the start of September, but there are still some very clean, glassy mornings of about 4ft to 5ft on offer. It’s a great period of surf.

So, if you're after the cleanest, most powerful, and most reliable surf in this window, your best bets are Friday morning the 28th of August for the big, glassy, expert swell, and Saturday the 23rd of August for a slightly smaller but still superb session for experienced surfers.

Rusty.
