Black Rocks Jetty Surf Forecast and Surf Report

Hey, Rusty here. Look, we've only got one spot in the window, but it's a good one. Black Rocks Jetty is on the cards, and it's looking like a run of solid, clean swells, especially for those who know what they're doing. The water temp is sitting at about 76° right now, which is about a degree and a half warmer than normal for this time of year, so it's pleasantly balmy.

The first action kicks off Friday afternoon, the 11th of September. It won't be huge, with a 4ft south swell, but the wind is glassy from the north. It's a touch inconsistent, but the conditions will be super clean. The energy is moderate at (775).

Saturday the 12th is a step up. Morning sees a 5ft SSW groundswell with a long 14-second period and a light cross-off wind from the NNW, making for some clean lines. The energy is still moderate (784). By Saturday afternoon, it goes dead glassy with a calm wind, and that same 5ft, 14-second SSW swell – a real treat.

Now, the standout. Sunday morning, the 13th of September. This is the one. We've got a 5ft SSW groundswell pumping with a very long 17-second period. The energy jumps right up to (1820), and with glassy conditions and light west winds, it's going to be epic. This is for experienced surfers only, as that long-period groundswell will be powerful and a bit tricky at a beach break, but for the reef at Black Rocks, it's going to shape up beautifully. This is the best of the run.

Sunday afternoon gets a bit wind-affected with a light cross-on, and the swell pushes to 6ft. It's still got strong energy (1857), but the quality drops. Monday the 14th is a write-off with onshore winds, so skip it.

Tuesday the 15th is another cracker. Morning glass with a 5ft, 18-second SW groundswell – that's a very long period. The energy is strong at (1506). Afternoon is even better: glassy winds, 5ft SW swell with a 17-second period, and a massive energy reading of (2064). This is the second standout window – pure, powerful, clean waves.

Wednesday the 16th is the biggest of the bunch. Morning is glassy with a 8ft SSW swell at 15 seconds. That's a heavy one, with very strong energy (2757). This is expert territory only. The afternoon gets a bit messy with a cross-on wind, so hit the morning session.

After that, the week settles down. Thursday the 17th through to the weekend of the 20th sees smaller swells (3ft to 4ft) but plenty of glassy conditions. It'll be clean, fun, and much more manageable for those who aren't experts.

Then we get another pulse. Monday the 21st of September looks promising, with a glassy morning and a 5ft SW groundswell, 17-second period, and strong energy (1178). Tuesday morning the 22nd is a little more crossed up, but Wednesday afternoon the 23rd comes back clean with a cross-off wind and a 5ft SW swell.

The last few days, from the 24th onward, see the swell dropping off into the 2ft range with clean conditions, but the energy is weak. By the 26th of September, it's pretty much done. There's a gap of a few days with no real recommendations at the very end.

So, your best bets: Sunday morning the 13th and Tuesday the 15th. Mark 'em.
Rusty.
