Black Rocks Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a look at what’s on the cards for this little region.

Right off the bat, it’s a bit of a slow start. We’ve got a run of dodgy conditions and marginal surf hanging around, so don’t expect much for the first week or so. There are a few pulses of solid swell but the wind just won’t play ball. The standout window is looking like the very end of the run, around the 23rd.

We kick off with Black Rocks on Saturday the 12th. The morning has some cross-off wind from the east, with a 6ft SSW swell on a very long 15-second period. The energy is pumping (1364) but it’s labelled marginal. The water is sitting at 76°, a touch warmer than normal for this time of year. The afternoon goes cross and drops a bit. Not the day to charge.

Sunday the 13th holds a bigger, cleaner pulse. The swell height sits around 5ft to 6ft from the SSW, with a mouth-watering 18-second period on the morning session. The combined energy is right up there (2042 and 2086). The wind is light and cross-on, then cross. The reports say “marginal” but that long period groundswell will be wrapping beautifully around the reef. This is a day for the experienced lot – the period is so long it can make the waves a bit walled at a beach, but at a reef like Black Rocks it’s going to be proper. The downside? It’s inconsistent here and crowds are often a thing.

Then it turns ugly. Monday the 14th through to the Tuesday the 16th is a write-off. Strong winds from the southeast and east turn the ocean into a messy chop. The swell gets big – up to 10ft on Wednesday the 16th – but with those fresh cross-shore winds and lumpy chop, it’s a kite surfer’s dream, not a paddle surfer’s. Stick to the beach on those days.

After that, from Thursday the 17th through to the Tuesday the 22nd, the surf is mostly small and weak. Energy levels drop to the low hundreds, even dropping to 215 at one point. The wind stays cross or cross-off, so it’s clean but tiny. You’ll be fighting for an ankle-snatcher.

Now, here’s where it gets good. Wednesday the 23rd of September is your standout morning. The swell picks up to a solid 7ft from the SSW, a 15-second period, with a cross-off breeze from the northeast. The combined energy is strong at 1795, and conditions are reported as “excellent surf for experienced surfers.” That swell is going to be overhead plus, so unless you’ve got some experience under your belt, give it a miss. But for those who can handle it, this is the pick of the forecast. Then the afternoon goes glassy – zero wind – with a 6ft SSW swell. That’s the cleanest the ocean will be for the whole 16 days.

After that, it tails off again through the 24th to the 27th with smaller, clean but ordinary waves. Not much to write home about.

So the bottom line: the 13th is a nice taste of long-period power but with a “marginal” tag, and the 23rd of September is your absolute best bet – punchy, clean, and packed with energy. Get it while it’s good.

Rusty.
