Black Rocks Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.

Honestly, the start of this run is a bit of a write-off. We’ve got a gap of no good surf from now until Monday morning, the 7th of September. The ocean’s been a mess with a strong cross-onshore wind and a lot of energy, but it’s just lumpy and poor. You’d be fighting a losing battle.

But then, Monday morning the 7th, things flip. It goes glassy – dead calm – at Black Rocks. That’s a reef break for advanced surfers only, and it’s an inconsistent one, so you gotta be patient. But when it’s on, it’s on. The water is sitting at 57°, which is a bit colder than normal for this time of year, so factor that in. We’ve got a clean 4ft swell from the WSW with a period of 14 seconds, giving it a solid groundswell feel. The combined energy is strong at 1080 (moderate to strong). It’s not a massive day, but the glassy conditions make it a standout for the cleanest waves you’ll see all week. Crowds are likely here, so get in early.

Monday afternoon stays good – a light cross-offshore breeze and a 5ft SW swell, period 13 seconds. Still clean, still good.

Tuesday the 8th drops right off. Swell down to 3ft and period dropping to 10-12 seconds. It’s marginal, light cross-shore wind. Nothing to write home about.

From Wednesday the 9th through to Friday the 11th, it’s all blown out again. Strong cross-onshore winds, choppy, lumpy. On Thursday the 10th, the swell jumps to 8ft with 16-second period, but with a 35 km/h cross-onshore wind, it’s just a washing machine. Not for paddle surfing – if you’ve got a kite, that’s your call.

The weekend of the 12th and 13th stays poor. Strong winds, messy surf. Even the 7ft SW swell on Saturday afternoon is wrecked by a 35 km/h cross-onshore.

Then, a bit of a tease on Monday the 14th – clean cross-offshore wind, but the swell is down around 3ft to 4ft. Marginal.

Now, for the real highlight in the second week. Look ahead to Saturday the 19th of September. Black Rocks finally lines up. Morning sees a 5ft SW swell, period 15 seconds – that’s very long-period groundswell, so expect well-shaped waves but long waits between sets. The wind is light cross-offshore. Combined energy is strong at 1397. It’s an excellent window for experienced surfers. The afternoon holds up too with 6ft and clean conditions. That’s the one to circle on your calendar, though it’s a long-range call so keep an eye on it.

Sunday the 20th is also clean, with a 6ft SW swell and light offshore wind in the afternoon. Good, but not quite the standout of Saturday.

After that, Monday the 21st turns back to cross-onshore chop. And that’s your lot.

Rusty.
