The Lowdown

Hey folks, Rusty here. Let’s take a look at what’s cooking over the next couple of weeks in surf units you can feel. It’s a quiet start on Friday (August 7th) with barely a ripple, so don’t bother paddling out just yet. The real action gets going from Saturday.

The standout run begins Saturday morning (August 8th) at Black Rocks Jetty. We’ve got a solid 4ft of SW swell with a period of 18 seconds – that’s proper groundswell, tons of energy and good shape for the reef. Winds are glassy, so it’ll be clean as a mirror. The combined swell energy is 779 (moderate), and the water’s sitting around 77°, a touch warmer than normal for this time of year. This is the pick for the weekend: clean, punchy, and consistent. By Saturday afternoon the swell ticks up to 4ft with a 16-second period, still glassy, and energy bumps to 858 – it’s going to be fun all day.

Sunday morning (August 9th) is another stunner: 4ft of SW swell, 15-second period, dead calm winds – glassy perfection with 619 energy. Just remember, with that long period, it could wall up a bit on a beach break, but here on the reef it’s a dream. Sunday afternoon gets a little tricky with onshore wind.

Monday (August 10th) keeps the good run going. Morning offers 4ft SW swell, 14-second period, glassy wind, and 753 energy. Afternoon is even better with 4ft SW, a jump to 16-second period, and 904 energy. Still glassy. Tuesday (August 11th) is another solid day with 4ft SW, 14-second period, and glassy wind – energy at 676 in the morning and 598 in the afternoon.

Wednesday morning (August 12th) sees a bit of onshore wind, but the afternoon cleans right back up with 4ft SW, 14-second period, and glassy conditions. The real highlight of the whole forecast, though, lands on Thursday August 13th afternoon and Friday August 14th. Thursday afternoon brings 6ft of SW swell at a 12-second period, energy climbing to 1019 (strong), and glassy wind – excellent for experienced surfers. Friday morning (August 14th) we get 7ft of SSW swell, 13-second period, and an energy reading of 1568 (strong). That’s serious size and power. Not one for the groms. Afternoon holds 6ft SSW at 12 seconds, energy at 1528, still glassy.

Saturday August 15th afternoon is a standout for the second week: 7ft of SSW swell with a very long 18-second period, cross-offshore wind, and a massive energy reading of 3745 (very strong). This is a powerful, clean groundswell – expert only. Sunday August 16th is another big day: 8ft SSW swell, 16-second period, dead calm in the morning, glassy, with 2748 energy. That’s big-wave territory.

Things ease up heading into the second week, but stay very good. Monday August 17th offers 5ft SW swell, 16-second period, glassy, with 1376 energy. Tuesday August 18th is still solid at 4ft, 15-second period, glassy. From Wednesday August 19th onward the swell drops off significantly, with smaller waves and more marginal wind through the 21st and 22nd. The last decent pulse is early on the 17th and 18th, so plan your sessions around that first run.

In short: Black Rocks Jetty is looking prime. The best windows are Saturday through Monday of the first week, and then the big stuff on Thursday/Friday and the following weekend. For the crew with bigger boards, the 14th and 15th of August are the real deal. Glassy conditions, long-period SW groundswell, and serious energy when it gets big. Get out there.
