The Lowdown
Alright, let's talk Black Rocks Jetty for the next couple weeks.
We’re looking at a tiny, glassy bump to start Thursday, September 3rd. Knee-high water, a bit warmer than usual at 77°F. The energy is low, just 146. Not worth suiting up.
Friday the 4th sees it start to grow a little, but with that cross-shore wind, it’s a scratchy mess. Then Saturday the 5th is the first real day. A 5 ft SW groundswell, 14-second period, glassy morning. The energy jumps to 1094, and the waves have real shape. This is for the experienced crew. Sunday the 6th stays glassy with 4 ft waves – clean and fun.
Monday the 7th gets messy with onshore wind. But Tuesday the 8th is one of the standouts. Tuesday afternoon has a pumping 10 ft SSW swell with a 15-second period, glassy calm, and energy blasting up to 6617. This is expert territory. Wednesday the 9th is even bigger: nearly 12 ft SSW swell, an 18-second period, and a wild energy of 7140. The wave quality will be insane. Those two days are the absolute best of the run.
The surf backs off through the rest of the first week and into the second. Thursday the 10th is still excellent with 6 ft glassy surf. Friday the 11th stays clean around 3 ft. By the weekend of the 12th and 13th, it’s waist-high and fun on the glass.
Then we get another monster on the 16th of September. Wednesday the 16th shows a 15 ft SSW swell with an 18-second period, glassy conditions, and an energy reading of 12658. That's huge, expert-only territory. The following days hold overhead, but much safer.
It’s a reef, so that long-period swell will grind and barrel. Expect crowds on the big days. The near-term is solid, and that 16th call is a big promise a little way out.
Stay safe out there.
