The Lowdown

Alright, Rusty here, let’s talk about what’s cooking at Black Rocks Jetty.

We’ve got a solid run of waves ahead. It’s not huge initially, but the quality is there. The water temp feels pretty standard for this time of year, so just your usual wetsuit job.

Kicking off Thursday morning the 6th, it’s glassy with some clouds and a clean 3 ft SW swell pushing through with 283 units of energy behind it. Not big, but that 13-second period means it’ll have some push. Glassy as anything. The afternoon cleans right up again with a slight shift to SSW.

Friday the 7th carries that same vibe early with 3 ft and 12 seconds – glassy, slight air. The afternoon gets weird though; the swell drops to 1 ft but the period jumps to 22 seconds. That’s some very long-period groundswell energy, which can make for weirdly straight lines over the reef, but when it’s glassy, it’s still fun for a quiet session. Energy is low at 337, so it won’t have much grunt.

Then we hit the sweet spot. Saturday the 8th morning is the standout. We’re looking at 4 ft of SW swell at 18 seconds, and it's clean and glassy. The combined energy jumps right up to 779, which is a massive leap. This is proper groundswell – racy, powerful, and because it’s a reef, those long-period lines will groom in nicely. Absolute glass. This is the one to circle.

Sunday the 9th keeps the quality high: 4 ft SW at 15 seconds, glassy, clean, with 626 units of energy. Monday the 10th gets a bit of cross-shore wind, so the face won’t be perfect, but the swell sticks around at 4 ft. Tuesday the 11th turns glassy again, and Wednesday the 12th brings the same magic with 5 ft at 14 seconds and 802 energy – felt that one in my bones, clean as a whistle.

The second week starts showing some grunt. Thursday the 13th gets a bit messy with a 12 mph cross-onshore and a 8 ft swell – that’s getting big for the average punter, and only for experts. Friday the 14th afternoon finally cleans up with a cross-offshore breeze and a solid 7 ft SSW swell at 13 seconds and a huge 2338 energy reading. That’s for experienced surfers only.

Saturday the 15th is another absolute standout. Morning glass, 5 ft SW at 19 seconds, with 2628 energy. That’s a very long-period swell, perfect for this reef set-up. The power will be proper. By the afternoon, it’s 6 ft and glassy. Sunday the 16th morning is a little weird with an onshore wind, but the afternoon turns glassy again with 7 ft SSW at 16 seconds – expert territory.

Monday the 17th still has good leftovers: 6 ft in the morning, 5 ft in the afternoon, both glassy. The energy tapers off through Tuesday the 18th and Wednesday the 19th, with smaller clean waves in the 2 ft to 3 ft range. The period stays around 12 to 14 seconds, so still fun for logs or a longboard, but the energy is way down, under 400. Thursday the 20th and Friday the 21st stay small, with a few clean glassy mornings and some longer-period groundswell showing up again on the 21st – 2 ft at 16 seconds with 321 energy. Good for a grovel.

Crowds are “sometimes” here, so you’ve got a decent chance of getting your share, especially if you pick the glassy windows.

Stay sharp out there.
