The Lowdown
Alright, this is Rusty, and I’ve got a good look at the forecast for Black Rocks Jetty. This is a reef break, and it’s a spot that knows how to handle a proper swell. The water’s sitting at 76° right now, which is a touch warmer than usual for this time of year, so you’ll be comfortable in a spring suit.
We’ve got a slow start. Sunday the 19th is a write-off – small, weak, and cross-onshore. The combined energy is a weak 452, and it’s just not worth paddling out for. Monday the 20th is where it kicks off. The morning is glassy, with a solid 7ft SSW groundswell. The energy jumps to 1987, which is moderate, and the period is 14 seconds – that’s got some proper push. This is a standout for the week. It’s a good size for experienced surfers and the wind is off the land, so it’s going to be clean. The afternoon stays glassy with a 8ft swell and 1859 energy. That’s two sessions in one day, and it’s going to be good.
Tuesday the 21st still holds strong with a 6ft SSW swell and 1112 energy. The morning is clean with a cross-offshore wind, but the afternoon gets a bit cross-shore, so get out early. Wednesday the 22nd is another glassy morning, 5ft of S swell at 979 energy. The wind is dead calm, so it’ll be like a mirror. The afternoon gets a bit choppy with a cross-onshore. Thursday the 23rd has a glassy morning again, 4ft S swell, and the energy is 749. It’s smaller but still clean. The rest of the week into the weekend is mixed, with smaller swells and cross-onshore winds, so not worth rushing out for.
Now, the real standout is lurking in the second week. Sunday the 2nd of August. The morning has a 10ft SSW swell, but it’s the afternoon that’s truly special. The swell jumps to 15ft from the SSW with a period of 13 seconds, and the combined energy is a massive 10932. That’s very strong energy. The wind is dead calm, glassy. This is an expert-only session. It’s going to be big, powerful, and perfect. Monday the 3rd of August is still huge, 12ft in the morning with glassy conditions, but it’s a step down from that Sunday afternoon. That Sunday is the one to circle on the calendar. It’s a bit far out, so keep an eye on it, but if it holds, that’s the best of the whole forecast.
All in all, there’s a lot of good surf here. The first week has a few top-tier sessions, but that Sunday the 2nd of August is the one that’ll have you cancelling your plans. Expect some crowds at Black Rocks, especially on the good days, as it’s a spot that draws people when it’s on.
