J-Bay Surf Forecast and Surf Report

Hey, it’s Rusty. Let’s break down the next couple of weeks. We’ve got some serious swell coming through J-Bay, but the wind is going to be a factor. The water is sitting at 59°, which is about 7° colder than usual for this time of year – that’s a proper chill, so make sure you’ve got a thick wetsuit.

Things kick off on Thursday the 6th of August with a solid 12ft SW swell, a 13-second period, and a combined energy of 4669 (moderate). The wind is a cross-off from the SW, so the waves will be clean. But that’s over 8ft, so this is strictly for the experts. The wind picks up in the afternoon, making it a bit choppy.

Friday the 7th sees the swell drop to 10ft, but the wind swings to the ENE and goes cross-on, ruining the surface. By the afternoon, it’s a mess. Saturday the 8th is better with a clean cross-off wind from the WSW, but the swell is down to 8ft in the morning with 2618 (moderate energy). The afternoon is a bit smaller.

Sunday the 9th brings a new pulse of 12ft to 13ft swell with heavy rain and strong onshore winds – that’s a blown-out day. Monday the 10th and Tuesday the 11th are marginal with cross-on winds, keeping the quality low.

Now, here’s a real gem. Saturday the 15th of August, the afternoon session is a beauty. We’ve got a clean 5ft SW swell, 16-second period, with a light cross-off breeze from the SSW. The energy is 1864 (moderate), but the conditions are “excellent for experienced surfers.” This is a standout – that long period (over 15 seconds) will give it some real grunt and shape, perfect for a point break like J-Bay. Crowds can be a problem here sometimes, so get out there early.

Sunday the 16th morning is also clean with a 5ft SW swell, but the energy drops a bit (1051). Still a fun size.

Then we hit a real highlight. Wednesday the 19th of August, the morning is absolutely glassy – zero wind, calm as a lake. The swell is 7ft from the SW, 10-second period, with 1043 (moderate energy). That’s a proper, clean, shoulder-to-head-high day with no wind bump. Expert-level size, but for the crew that can handle it, this is the pick of the fortnight.

The final standout is Friday the 21st of August. The morning is glassy again with a 6ft SSW swell and a 13-second period – 1362 (moderate energy). That’s a beautiful, clean wave. But watch the afternoon: a massive 13ft SSW swell rolls in with a 17-second period and an energy reading of 8174 (strong energy). That is a monster groundswell, and with almost no wind, it’s going to be a serious, heavy, expert-only session. Sets will be long and powerful. For the average surfer, this one is a beast.

Overall, the best windows are the afternoon of Saturday the 15th, the glassy morning of Wednesday the 19th, and the glassy morning of Friday the 21st. That last afternoon on the 21st is a jaw-dropper for the big-wave crew.

Rusty.
