Black Rocks Jetty Surf Forecast and Surf Report

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

We’re looking at a solid stretch ahead at Black Rocks Jetty. The water is sitting at 77°, which is a touch warmer than we’d normally expect for this time of year, so that’s a nice little bonus.

The first few days are a bit of a tease. Sunday afternoon (9 August) and Monday (10 August) have some waist-high swell around 4ft from the SW, but the conditions are marginal. The wind is light, but it’s not quite clean. We’ve got moderate wave energy in the water (739 to 923), but it’s just not coming together yet. You might get a few, but it’s not worth rushing out for.

Then we hit Tuesday morning (11 August) and things start to look up. The swell holds at 4ft from the SW, but the wind goes glassy. That’s the magic word. Clean, smooth lines rolling in with moderate energy (611). It’s not going to be huge, but it’ll be fun and ridable. Tuesday afternoon stays clean with a light cross-offshore breeze.

Wednesday (12 August) morning is a bit bumpy with a cross-shore wind, but the afternoon drops to glassy again. That same 4ft SW swell is there, and the water will be feeling good. Still, the real standout action is coming.

The first big highlight is Friday morning (14 August). We’re looking at 6ft of SW swell, a 13-second period, and the wind is dead calm. Glassy perfection. The combined energy jumps to 1237, so there’s some real push in the water. This is groundswell, a bit long period, so it’ll set up nicely on this reef. It’s a bit solid for beginners, but for experienced surfers, this is the session to circle.

The absolute standout is Saturday morning (15 August). The swell drops back to 4ft, but the period stretches to a massive 20 seconds. That’s very long period groundswell. The energy is pumping at 2094, and it’s glassy with no wind. This is going to be a dream on the reef. Long, clean, powerful lines. It’s not big, but the quality will be exceptional. This is the best on offer.

Sunday morning (16 August) gets a bit larger, with 8ft of SSW swell and a 16-second period, combined energy at 3506. That’s for experts only. Still glassy, so it’ll be a sight to see, but only for the brave.

After that, the swell backs off again through the middle of the week, with smaller waves in the 2ft to 3ft range. Conditions are often still clean, but it’s a lull.

Then we get another promising pulse on Friday morning (21 August) with 8ft of S swell, 12-second period, and glassy conditions. Energy is up at 2200. Again, expert territory. Saturday morning (22 August) holds similar size at 8ft, but the wind picks up a bit in the afternoon, getting choppy.

The final days of the forecast (23-24 August) see the swell drop back down to waist-high, but the period stays solid on the 24th with 17 seconds, and it’s glassy. A nice, clean wind-down to the run.

One thing to note: Black Rocks Jetty can get crowded sometimes, and it’s a reef break, so keep your wits about you. The SW swell is right in the sweet spot for this spot.

The bottom line: Saturday morning (15 August) is the one to wake up early for. Friday morning (14 August) is a very close second. The rest of the run has some fun windows, but those two are the standouts.

Rusty.
