Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what’s on the menu for the coming weeks.

We’re looking at a solid run of surf coming up, but it’s not all plain sailing. The first few days are looking really good, with a sweet, long-period groundswell from the southwest. The water is sitting at 77°F and is a touch warmer than normal for this time of year, so that’s a nice bonus. The standout period is right at the start.

Black Rocks Jetty will be the place to be this Saturday morning, August 8th. It’s glassy, absolutely dead calm, and we’ve got a 4ft southwest swell with a very long 18-second period. The combined energy is moderate (779). This is a proper reef break and with that long period, it’s going to hold up beautifully. Expect clean, lined-up waves. The crowd factor is “sometimes” here, so you might have a few mates out, but it’s nothing crazy.

Saturday afternoon sees a slight increase in size to 4ft, still from the southwest, with a 16-second period. The wind is still glassy, with just a whisper of a breeze from the swell direction itself. The wave energy is kicking up a notch (867). It’s still very good.

Sunday morning, August 9th, is another glassy, clean one with a 4ft southwest swell and a 15-second period. Energy is still solid (618). Honestly, this is the kind of start to the weekend you dream about.

Monday morning, the 10th, things get a bit tricky. The swell is still there at 4ft, but a light cross-shore wind from the WNW starts to mess with the surface. It’s still surfable, but the magic is gone. That clean, glassy feel is the key to this spot.

Tuesday morning, the 11th, we get a return to glassy conditions with a light NW breeze, and the 4ft swell is still ticking over. By Tuesday afternoon, the wind swings to the east, but it’s still glassy. This is a solid, consistent run of swell.

The real standout, though, is the forecast for Saturday, August 15th. This is a mark-your-calendar situation. Saturday morning, we’re looking at an 8ft SSW swell with a very long 19-second period. The combined energy is huge (5787). The wind is glassy, just a light air from the SSE. This is expert territory – over 8ft is only for the experienced crew. The break is a reef, which is perfect for this kind of long-period groundswell, so it won’t be a close-out. The afternoon gets bigger, hitting 12ft, but the wind turns cross-onshore, so it’s not as clean. The morning session is the absolute winner.

Sunday, August 16th, the swell drops slightly to 8ft but still has a solid 16-second period. The morning is glassy with a light NW wind. Excellent for experienced surfers.

After that, the swell slowly fades through the second week. There are still some fun, clean days with 4ft to 4ft waves, but the energy is lower. By the 21st and 22nd, we’re into small, clean leftovers in the 2ft to 3ft range. It’s rideable, but nothing to get too excited about.

So, the call is clear: Saturday morning August 8th through Sunday morning August 9th is your go-to for clean, fun waves. The absolute standout is the morning of Saturday, August 15th for the big, powerful, glassy swell – but that’s only for the experts.

Rusty.
