Black Rocks Jetty Surf Forecast and Surf Report

Alright, this is Rusty looking at Black Rocks Jetty. It's a reef break, very consistent when the swell is from the southwest, and it's for advanced surfers only. Don't take a foamy out here.

We kick off on Monday the 27th of July. Monday morning is glassy, with a solid 7ft southwest groundswell. That's a long period of 16 seconds, so it's packing a punch. The combined energy is very strong (3761). The water temp is about normal for this time of year. This is excellent for experienced surfers.

Monday afternoon, the swell jumps to 10ft from the southwest, but the wind comes onshore, ruining the quality even though the energy is still very strong (3827). The real standout window is Tuesday the 28th through Wednesday the 29th of July. Tuesday morning is glassy with a 7ft southwest swell, 15-second period, and very strong energy (2777). Tuesday afternoon gets a cross-on wind, but Wednesday is back to glassy in the morning with a 7ft south-southwest swell, and Wednesday afternoon is dead calm. That Wednesday afternoon is a gem: 6ft, glassy, and super smooth. This spot can get crowded sometimes, so get on it early.

The run continues into the end of July. Thursday the 30th and Friday the 31st keep the quality with glassy mornings and clean surf, swell sitting around 5ft to 6ft with periods of 13 to 16 seconds. The energy is strong throughout. Saturday the 1st of August gets a bit messy with onshore winds and cross-shore conditions. The swell is still around 6ft with strong energy (1721), but the wind is not your friend.

Sunday the 2nd of August is glassy again, but the swell drops to 4ft. The period is a very long 19 seconds. The energy remains strong (1783), but that long groundswell might make it a bit too straight for this reef. Monday the 3rd of August is small at 4ft with moderate energy (982). The first week of August sees a drop in size and energy, with a few days of weak, marginal waves around 3ft to 3ft.

There’s a gap in quality through the middle of the week, but it picks up on Wednesday the 5th of August. We get a clean, glassy morning with a 5ft southwest swell and strong energy (1538). Thursday the 6th is still okay at 5ft, but the energy is moderate. Friday the 7th and Saturday the 8th are very weak, with combined energy as low as 353 to 511. Not worth paddling out for.

The outlook improves again from Sunday the 9th of August. It starts small at 3ft but glassy, with weak energy (517). Monday the 10th gets better, with a 5ft southwest swell and energy climbing back to moderate (926). The highlight for the second week is Monday the 10th afternoon and Tuesday the 11th of August. Monday afternoon sees a jump to 5ft, glassy, with a 15-second period and strong energy (1191). Tuesday the 11th morning is the best of that late run: 6ft from the southwest, glassy, with a 15-second period and strong energy (1263). That’s the one for the crew who know what they're doing.

The second half of the first week is a write-off. The standout windows are the glassy mornings around the 27th to 29th of July and that cleaner patch around the 5th, with the long-range pick being Tuesday the 11th of August. Water is average for the season. When it’s glassy here, it’s hard to beat.

Rusty.
