The Lowdown
Alright, Rusty here. Let’s have a look at what’s comin’ down the pipeline for Black Rocks Jetty.
We’ve got a solid run of surf on the way, starting with a bang on Friday, July 31st. We’re looking at a strong SSW groundswell, with a very long period of 16 seconds, piling in at 6 ft. The combined wave energy is pumping at a strong 1305. This is proper groundswell, so expect those long, clean lines that are a dream on a reef setup like this. Winds are light and cross-offshore in the morning, going glassy in the afternoon. This is definitely one for the experienced crew – the size and power make it a no-go for beginners. The water temp is about average for this time of year.
Saturday, August 1st, keeps the good times rolling. The swell holds at 6 ft from the SSW, with a period of 15 seconds, and the combined energy is even stronger at 1447. Glassy winds in the morning promise some of the cleanest conditions you’ll see all week. This is a standout day.
Sunday the 2nd has the swell backing off to 3 ft in the morning, but don’t sleep on it. That glassy West wind and long 16-second period will have the joint looking fun again for those who know the reef. After that, the middle of next week drops into the 2 ft to 4 ft range. It’s still clean, with a lot of glassy conditions, but you’re on the smaller end. There’s a dip on Thursday the 6th where the wind gets a bit messy, but we bounce back nicely.
Now, keep an eye on the second weekend. Saturday, August 8th starts showing signs of life, and then Sunday the 9th through Monday the 10th is where we get another serious window. Sunday the 9th sees the swell return to 5 ft from the SW with a very long 16-second period and glassy winds – combined energy hits 1275 in the afternoon. That’s a beautiful forecast for an advanced wave. Monday the 10th is the peak of this second pulse, with 6 ft from the SW, a very long 15-second period, and perfectly calm, glassy winds. The combined energy is strong at 1358. This is another true standout, but remember, it’s more than a week away, so a little less certain. Still, it’s got all the ingredients.
Crowds are possible at Black Rocks Jetty, as it’s known to get busy sometimes. It’s a very consistent reef break, so it’s worth the paddle.
All in all, if you’ve got the skills, the end of July kick-off and the second weekend in August are your best bets. The surf fades out into the middle of the second week, with the last real call being on Saturday the 15th with a clean 3 ft SSW groundswell.
Stay stoked,
Rusty
