Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it.

We’ve got a solid run of winter swell on the way for Black Rocks Jetty, and it’s all about the timing. The first few days are the real deal for experienced surfers, with a proper groundswell and glassy conditions. The water temp is sitting about average for this time of year, so you’ll need a decent wetsuit.

The standout window kicks off Saturday morning, August 1st. We’re looking at a clean 6ft SSW groundswell with a period of 15 seconds, and the wind is dead glassy from the NE. The combined energy is strong (1314), and the waves will have serious push. This is a reef break, so it’s an advanced-only affair. The sets will be long and lined up, but that long period (15 seconds) means it’s going to hold up beautifully on the take-off. Sunday morning, August 2nd, is almost a carbon copy: 5ft SSW groundswell, 14 seconds, glassy WSW wind, and energy at 1084. Beautiful, clean conditions.

The best of the whole run, though, is shaping up for Tuesday morning, August 11th. It’s a couple of weeks out, so keep an eye on it, but the forecast is mouthwatering. Calm, glassy conditions with a 5ft SW groundswell, a very long 18-second period, and combined energy hitting 1724. That’s a powerful, long-period groundswell that will hump up nicely. Because it’s a reef, that long period is a massive plus – it’ll wall up perfectly. It’s a true standout for the experts.

Saturday morning, August 15th, also looks like a cracker for the experienced crew. Clean, calm conditions with a 5ft SSW groundswell, 14 seconds, and energy at 1254. The afternoon session on the 15th is even bigger, with 5ft SSW groundswell, 16 seconds, and energy at 1484. Both sessions are glassy.

There are a few smaller days in the middle of the run, like the 5th through the 7th, with waves around 2ft to 3ft – still rideable on a log, but nothing to get worked up about. The 8th has a very long 18-second period but only 2ft of swell, so it’s a bit of a tease. The 14th afternoon gets a bit choppy with a cross-onshore wind, so that’s a pass.

To wrap it up: the first weekend (August 1st and 2nd) and the mornings of August 11th and 15th are your best bets. Crowds are just a possibility at Black Rocks, so it shouldn’t be too hectic. This is a reef break for advanced surfers looking for a proper, powerful wave.

Rusty.
