Black Rocks Jetty Surf Forecast and Surf Report

Gather 'round, crew. Rusty here. We’ve got a solid run of swell on the way for Black Rocks Jetty, but you’ve gotta be experienced to handle what’s coming. This is a reef setup, exposed to the southwest, so it knows how to handle a proper groundswell. The water temp is pretty much what you'd expect for this time of year, nothing weird going on there.

The week kicks off with a real bang. Monday morning, July 13th, we’re looking at a clean 7 ft SW groundswell with a 14-second period. The wind is glassy from the east, so the surface will be a dream. The combined energy is pumping (1893), and it’s offering excellent surf, but only for the advanced crew. The direction is bang on the optimum. This is the standout of the entire forecast. Monday afternoon holds similar size and quality, just a touch smaller at 7 ft from the SSW, still glassy.

Tuesday morning, July 14th, is another gem. The swell drops a bit to 6 ft, but it’s glassy calm with a 14-second period from the SSW. The combined energy is still strong (1093), and it’s another excellent session for the experienced. Tuesday afternoon sees the swell back off to 5 ft, still glassy, and the energy drops to 796. It’s very good, but the wind shifts to a light onshore from the SW, so it’s not quite as clean as the morning.

Wednesday morning, July 15th, is still very good with 5 ft of SW groundswell (12-second period) and glassy NE winds. The energy is moderate (531). By Wednesday afternoon, the swell is down to 4 ft, and while it’s glassy, the energy is dropping (367). Still good fun, but the magic is fading.

Thursday, July 16th, is a write-off. The swell drops to 2 ft, and the wind goes cross-off and then onshore. Energy is weak (196). Poor conditions.

Friday, July 17th, brings a surprise morning session. The swell is tiny at 2 ft, but the wind is completely glassy. The period is a very long 17 seconds from the south. The combined energy is 315, which is surprisingly good for the size. This is a sneaky good one for the longboard or a step-up if you can find the juice. The afternoon turns to junk with a 4 ft onshore slop.

Saturday, July 18th, is a washout with small, onshore swell. Sunday, July 19th, morning looks promising again. A clean 3 ft SW groundswell with a 16-second period, glassy winds from the WSW, and solid energy (654). This is very good, but the swell is a bit small. The afternoon gets a bit bigger at 6 ft with a 20-second period (very long period), and the energy jumps to 2636, but the wind is cross-onshore, making it messy.

Monday, July 20th, is for experts only. The swell jumps to 10 ft from the SSW, with a 15-second period. The energy is massive (3479), but the wind is a 9 mph cross-onshore, which will make it lumpy and challenging. The afternoon is a total loss with 19 mph winds and rain. For the next couple of days, the wind is ugly, making the surf poor.

The next real highlight is Wednesday morning, July 22nd. After the wind settles, we get a glassy morning with 4 ft of S swell (11-second period) and clean energy (765). Very good conditions. Then, the real hidden gem is Friday morning, July 24th. A glassy, calm morning with 5 ft of SW groundswell, a 17-second period, and strong energy (1450). The conditions are excellent for experienced surfers. Saturday morning, July 25th, is another glassy winner with 5 ft of SW swell and a 16-second period, offering very good waves.

The final week looks average, with small to moderate swell and mostly cross-onshore winds. The best of that is Tuesday morning, July 28th, with 4 ft from the SW, an 18-second period, and decent energy (1249), but only marginal conditions due to the wind.

So, if you want the best of the best, get out on the water Monday morning, July 13th, and Tuesday morning, July 14th. Friday morning, July 24th, is also a ripper. This is a spot for the advanced crew, so don't be a hero if you're not ready.

Rusty.
