Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, let’s get into it. This is Rusty, and I’m looking at what we’ve got coming down the pipe for Black Rocks Jetty. It’s a reef setup, very consistent, and it needs a good SW swell to light up.

We’re starting off with a bit of a slow burner, but the wait is worth it. The first few days are small, but the real action kicks off from the second week. The water temp is about average for this time of year, nothing wild to report there.

Monday, August 3rd is the opener. You’ve got a clean 4ft SW groundswell with a 14-second period, and it’s dead glass. The combined energy is moderate (965). That’s a solid, clean start. The afternoon gets a bit of a cross-on breeze, but it’s still small.

Tuesday and Wednesday are tiny, with swell dropping to 2ft - 3ft. The period is still decent, but the size just isn’t there. Thursday is more of the same, with a bit of onshore wind, so it’s a skip.

Friday, August 7th is weird. The morning is flat but glassy, then the afternoon hits with a 2ft swell but a massive 22-second period. That’s a very long period groundswell, but it’s tiny. That long period will make the wave shape funky at a reef, but it’s more of a novelty than a proper session.

Now, here’s where it gets good. Saturday, August 8th morning is a standout. You’ve got a 4ft SW swell with an 18-second period, and the combined energy is strong (1008). It’s dead calm. The call is for excellent surf for experienced surfers, and I agree. That’s a proper groundswell. The afternoon gets a bit cross, but the morning is the pick.

Sunday the 9th and Monday the 10th keep the quality high with 4ft - 4ft SW swell, 14-16 second periods, and glassy mornings. The energy is moderate to strong (761-707). Very good surf conditions.

The 12th of August, Wednesday morning, is another cracker. 5ft of SW groundswell at 16 seconds, combined energy of 986. Glassy. That’s a beautiful, clean, powerful line-up.

The run from August 13th to 15th has some solid size. The 13th morning sees 6ft, but it’s a bit onshore. The afternoon, however, is glassy with the same 6ft, and that’s excellent. The 15th afternoon is a real standout: 5ft of SW swell with an 18-second period, combined energy is strong (1303). The wind is cross-off, so it’s clean. That’s a powerful, clean session.

Saturday, August 16th morning is the biggest clean swell of the window. 7ft of SW groundswell at 15 seconds, combined energy of 1741. It’s glassy. This is for experienced surfers only. The afternoon gets a cross-breeze, but that morning is a beast.

The 17th and 18th keep the size up, with 5ft to 10ft, but the winds are a bit more mixed. The 18th morning has a massive 10ft swell with a 15-second period, and the combined energy is very strong (4423). For a reef, that’s a serious, heavy wave. The wind is cross-shore, so it won’t be perfect, but the power is insane.

Best on offer: The standouts are the Saturday, August 8th morning for the perfect glassy conditions on a solid 4ft groundswell, and the Saturday, August 16th morning for the biggest, cleanest swell of the 7ft mark. The 15th afternoon is also a top-tier call with that long period and cross-off wind.

Crowds are listed as "sometimes", so you might have company, but this reef can handle a few. The setup looks too good for paddle surfing for a couple of those sessions to even think about kiting.
