Robberg Surf Forecast and Surf Report

G’day, Rusty here, looking at what’s on the cards for Robberg over the next couple of weeks. It’s a bit of a mixed bag, with a slow start, then a few solid windows, and a couple of monster swells that’ll be for the brave only. The water temp is about average for this time of year, so no need to overthink the rubber.

We kick off on Tuesday morning, 8 September, with a clean 4ft easterly swell at 9 seconds – that’s a short-period wind swell, but with light cross-offshore breezes from the ENE, Robberg is looking tidy. The combined energy is moderate at 709, and it’s a good chance to get a few fun ones before the crowd rolls in. That morning session is the pick of the early week.

The rest of the first week gets a bit messy. Wednesday the 9th sees the swell drop to 2ft with a proper glassy morning, but it’s a weak SW groundswell at 14 seconds – long period, so it’ll wrap in nicely, but the energy is low at 409. Wednesday afternoon is glassy too, but still small. Thursday the 10th brings a bigger jump, with 7ft SW swell by the afternoon, combined energy jumping to 1891 (moderate-strong), but it’s cross-on from the SSW and a bit lumpy. Not the cleanest.

Friday the 11th holds around 6ft, but the wind is cross-shore and a little stronger. Then we get to Saturday morning, 12 September – that’s the standout of the first week. The swell is 6ft from the SW, period 14 seconds, and it’s dead calm, glassy. The combined energy is strong at 1242, and it’s labelled excellent for experienced surfers. This is the one to aim for – clean, powerful lines at Robberg, and the crowd is only sometimes around, so you might score a few solo ones. The long period means it’ll be a bit more organised, better shaped, and the lulls between sets will make the paddle out easier.

After that, Sunday the 13th pushes up to 8ft, but it’s cross-on and a bit bumpy. Monday the 14th is cleaner with a cross-offshore wind, but the swell drops back to 4-5ft. Not a dud, but not the highlight.

Now, the second week kicks in with a run of big, heavy swells. Wednesday morning, 16 September – we’re looking at 12ft SW swell with a 19-second period – that’s a very long period groundswell. The combined energy is a massive 9407, strong to very strong. This is expert territory only. The wind is a gentle cross-onshore, so it’ll be a bit lumpy, but the raw power is there. By Wednesday afternoon, it’s 13ft and onshore, energy at 10562 – only for the brave. Thursday the 17th is still 12ft but cross-shore, still huge. Friday the 18th is a write-off – heavy rain, fresh onshore winds at 22 mph, and poor conditions. Don’t bother.

The following weekend (19-20 September) is still decent sized, 8-10ft, but the wind stays cross-on, so it’s a bit lumpy. The real standout of the second week is Monday morning, 21 September – 15ft SW swell, period 12 seconds, combined energy 5793, with light cross-on winds. Big, raw, and powerful. Then Monday afternoon hits 16ft SW, with a light cross-shore breeze, and the energy jumps to 9292 – that’s a massive, powerful swell, and the score is high. That afternoon could be the best session of the whole run if you’re an expert. The long period groundswell will be best at the reef and point sections at Robberg, as it’ll break a bit straight on the beach. Crowds are only sometimes, so you might get a share.

Beyond that, Tuesday 22 September is still 10ft in the morning, dropping to 8ft in the afternoon, with cross-shore winds. Wednesday 23 September backs right off to 4ft, and the energy drops to 877.

So, the true standouts: Saturday morning, 12 September for the clean, glassy, powerful lines at a moderate size, and Monday afternoon, 21 September for the absolute monsters if you’ve got the nerve. The rest is a mix of small, messy, or too big for most.

Rusty.
