Robberg Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about Robberg.

Right off the bat, the water is sitting at 58°F, which is a massive 6°F colder than it should be for this time of year. That’s very unusual, so bring the thickest wetsuit you’ve got.

The 16-day window kicks off on Wednesday the 16th of September, but for the first week, it’s a bit of a battle. We’ve got consistent swell around 7ft to 8ft from the SW and ESE, but the wind is all wrong—mostly cross or cross-on, with speeds picking up to 19 mph at times. The combined energy is moderate to strong (2744 on Wednesday morning, dropping to 1338 by Friday morning), but the quality is shot because of the chop. This is a beach and reef setup, and with that wind, it’s looking more like a kite session than a paddle surf. Robberg is inconsistent, so your chances are slim right now.

We hit a flat gap from Sunday the 20th through to Monday the 21st. The swell jumps to 10ft on Sunday with poor conditions and zero scores, so don’t even bother.

Now, Monday the 21st afternoon things change. We get a glassy window with 6ft of ESE swell (period 9 seconds) and only 3 mph wind, and the combined energy is 976. That’s the cleanest we’ll see for a while. It’s marginal surf, but that glassy wind is a major positive—it’ll be clean, and Robberg can hold a fun shape when it’s like this. Not a standout, but your best bet early on.

The real standout comes on Friday the 25th of September. That morning we’ve got a 13ft SW groundswell, period 15 seconds, with a cross wind at 12 mph. The combined energy is a meaty 6225—strong wave energy. The swell direction (SW) matches the optimum (SE) pretty well, and with that long period (groundswell, over 11 seconds), the wave shape should be solid. The wind is cross, not offshore, but it’s manageable. This is only for experts though—over 8ft and it’s too big for beginners. Saturday the 26th morning drops to 8ft, still with long period (13 seconds) and strong energy (3281), and the wind stays cross. That Sunday the 27th morning is a bit smaller at 7ft (SSW, 13 seconds, 1528 energy) with light cross winds—cleaner, but not the peak.

After that, it fades fast. By Monday the 28th, we’re down to 3ft and barely any energy (246), with poor scores through to the end of the window. The last week is dead, with combined energy dropping as low as 41 and waves under 2ft. No recommendations there.

So the pick of the run is Friday the 25th morning—big, powerful, and long period, but only if you’ve got the skills. Monday the 21st afternoon is the cleanest smaller session for the patient surfer. The rest is a write-off until that Friday.

Stay warm, and keep an eye on the sky.

Rusty.
