Black Rocks Jetty Surf Forecast and Surf Report

Alright, this is Rusty. Let's have a look at what's on the cards for Black Rocks Jetty.

We've got a solid run of surf coming up, but it's a story of two halves. The first few days are clean and fun, but the real muscle shows up late next week. The water here is sitting at 77° – a touch warmer than normal for this time of year, which is a nice bonus.

Things kick off on Thursday morning, August 20th. It's small, around 3ft from the SW, but the energy is surprisingly punchy for the size (371). The wind is a light cross-on, so it's not perfect, but it's surfable. The real action starts Thursday afternoon, though. The wind drops to glass, and that 2ft SW swell with a long 15-second period cleans right up. It's tiny but glassy, and you'll catch a few if you're patient.

Friday, August 21st, is where it gets going. We've got a clean 4ft SW swell, with a 14-second period. The wind is glassy or cross-off all day. This is proper, fun, longboard-to-fish kind of surf. The energy jumps to 611, which is moderate, and the quality is there.

Saturday, August 22nd, is a standout. The morning is glassy with 5ft of SW swell and an energy reading of 901. By Saturday afternoon, it's still glassy, and the swell holds at 5ft with a 13-second period. The energy climbs to 1053, which is getting into moderate territory. This is a great day for intermediate surfers.

Sunday, August 23rd, the swell pushes up. The morning is a beauty: 8ft from the SSW, glassy, with a massive energy of 2313. This is excellent for experienced surfers, but it's getting too big for beginners. The afternoon gets a bit messy with a cross-shore wind, so the morning is the call.

Monday, August 24th, is probably the best of the first week. The morning is calm and glassy, with a 8ft SSW swell, a 15-second period, and energy at 2536. The afternoon is also glassy and solid. This is expert territory, but if you're comfortable, it'll be a session to remember.

Surf tails off a bit on Tuesday, August 25th, but the morning is still a clean 6ft with glassy conditions. The afternoon turns onshore and messy. Wednesday, August 26th, offers a glassy 5ft in the morning, but the afternoon goes to crap with a strong cross-onshore wind.

Now, here's the big one. Thursday, August 27th, through to Saturday, August 29th, is the real standout window. On Thursday morning, we're looking at 8ft from the SSW with a 16-second period and energy of 3417, but the wind is a cross-shore, so it's a bit lumpy. Thursday afternoon, August 27th, is where the heavyweights come out. We've got an 12ft SSW swell, a very long 19-second period, and the energy is a massive 7929. The wind is a moderate cross-shore, so it's going to be a beast. This is only for experts. The period is so long, it'll be barreling, but it might be a bit straight at the beach. Keep that in mind.

Friday, August 28th, might be the pick of the whole run. The morning sees 13ft of SSW swell with a 17-second period and energy of 8217. The wind is a light cross-on, so it's still manageable for the pros. But Friday afternoon is the gold: 12ft, 16-second period, glassy, and energy of 6818. Exceptional conditions for expert surfers. The crowd factor is "sometimes" here, but with that size, it'll be quiet.

Saturday, August 29th, is still pumping with 8ft and glassy conditions in the morning, and another 7ft glassy session in the afternoon. A great way to end the big swell.

After that, the surf drops steadily through the end of August and into September. The first few days of September are small and mostly onshore, not worth a paddle. There's a small window on Thursday, September 3rd, with a glassy 3ft, and again on Friday, September 4th, with a glassy 4ft SW swell, but it's a shadow of the week before.

So, to sum it up: the best on offer is Friday, August 28th afternoon, with that glassy, 12ft SSW groundswell. It's a dream for the experts. The runner-up is Monday, August 24th morning, with the 8ft, glassy, long-period swell. Don't miss those.

Rusty.
