Black Rocks Jetty Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of surf coming up at Black Rocks Jetty, and if you’re an experienced surfer, you’re going to want to pay attention to the middle of this forecast. The water is sitting at 77°, which is a touch warmer than normal – a nice little bonus for this time of year.

The first real action kicks off on Friday afternoon, July 24th. It’s not the biggest, with a 4ft SW swell, but the wind is glassy and from the north. The wave energy is solid, sitting at 863 (moderate energy), and it’s a clean, mellow start to the weekend. Saturday morning, July 25th, keeps that 4ft SW swell going, but the wind swings to a gentle offshore from the NNE at 9 mph, cleaning it right up. That’s a good window for a session on the reef.

Now, Sunday morning, July 26th, drops a little in size to 3ft, but the period jumps to 20 seconds – that’s proper groundswell energy. The cross-offshore wind from the NNW keeps it tidy, but with that long period, the waves might be a bit straight for a beach break. This is a reef, so it should handle it nicely. The energy is at 737 (moderate).

Then we get to the real standout. Monday, July 27th. The swell jumps to 8ft from the SW, with a long 16-second period, and the wind is absolutely glassy. This is big, powerful surf. The combined energy is a massive 3624 (strong to very strong) for the morning, and 3365 for the afternoon. This is expert territory – over 8ft, it’s only for the skilled crew. If you’ve got the nerve, this is the best session of the whole forecast. The glassy conditions through Tuesday the 28th (7ft to 8ft, SW/SSW) and Wednesday the 29th (7ft to 6ft, SSW) just keep the quality high. Tuesday afternoon sees a 17-second period and 3301 energy – incredible.

Things start to ease off from Thursday, July 30th, but it’s still excellent. We’re looking at 5ft to 6ft SW swell with glassy winds, and energy staying in the four-digit range, which is still strong. This run of excellent conditions continues right through the end of July and into the first of August. Morning of August 1st is a glassy 5ft from the SSW, but the afternoon goes onshore, so get it early.

There’s a bit of a lull after that. August 2nd and 3rd see the swell drop to under 3ft, and the winds get messy, with onshore flow making things marginal. The energy drops into the hundreds. August 4th picks up a little with a 3ft to 5ft swell, but the wind is cross to cross-on, so conditions are a bit bumpy.

We get a nice little revival from August 5th through the 6th, with 4ft to 5ft SSW swell, glassy or calm winds, and energy in the 500 to 987 range. That’s clean, fun surf. The very end of the forecast, August 7th and 8th, has a mix of small, clean swells and some cross-onshore wind, but the 2ft swell on the 7th afternoon has a 18-second period and glassy conditions – a sneaky good one for the longboard.

So, to sum it up: the absolute standout is Monday, July 27th and Tuesday, July 28th. That’s the big, glassy, powerful groundswell for experienced surfers only. The second best window is the stretch from July 29th to July 31st, with consistently excellent, glassy conditions and solid 6ft to 7ft surf. Get out there.

Rusty.
