The Lowdown
Alright, Rusty here again, giving you the same rundown in feet and degrees Fahrenheit.
Robberg is a beach and reef setup that’s exposed to the swell, but it’s inconsistent, so you gotta watch the windows. The water is 59°F, which is way colder than normal, so don’t even think about a spring suit.
The outlook starts off average on Sunday the 30th with 7ft to 8ft of SW swell, period 9 to 12 seconds, but the wind is cross-onshore light, so it’ll be bumpy. The energy is moderate to strong (795 to 1464), but not clean.
Monday the 31st has a real bright spot. The morning is tiny at 1ft from the east, but the afternoon goes glassy with a clean 5ft SW groundswell at 12 seconds. That’s the standout early on. Energy is moderate (728), and glassy conditions make it the pick of the early days.
Tuesday the 1st of September brings 8ft to 8ft of SW swell, period 12 to 13 seconds, but the cross-on wind kills it. The energy is strong (1459 to 2107), but it’s messy.
Wednesday the 2nd gets bigger and uglier: 10ft of SW swell with a 14-second period, but cross-onshore wind at 9 to 12 mph. The energy is very strong (3637 to 2556). Honestly, this looks more like kite surfing conditions than paddle surfing.
Thursday the 3rd drops to 6ft to 5ft, but still cross-onshore and choppy. Friday the 4th is a total washout: 13ft to 12ft of SE windswell at 11 seconds, 19 mph cross-onshore winds, and energy through the roof (5246). Stay on land.
Saturday the 5th has a good one in the afternoon. Morning is iffy with 7ft of ESE swell and onshore wind, but the afternoon goes glassy with 5ft of ESE swell at 10 seconds. Energy is moderate (759), and glassy conditions mean clean waves.
Sunday the 6th brings a big 8ft SSW groundswell with a very long 15-second period, but cross wind at 6 to 16 mph. The energy is very strong (3074 to 2175). That long period will give good shape, but at a beach and reef break, it might be a bit too straight. The morning is better.
From Monday the 7th through Wednesday the 9th, it’s a mix of cross-shore winds and swell from 4ft to 10ft, but the wind is never clean. Periods drop to 7 to 8 seconds, so it’s short and junky.
Thursday the 10th of September is a gem. The morning is glassy with 5ft of E swell at 10 seconds, and the energy is moderate (727). This is the best of the second week—clean, glassy, and fun.
Friday the 11th and Saturday the 12th are poor again. Sunday the 13th is a blowout with up to 25 mph cross winds and 10ft swell—again, more for kite surfing.
Monday the 14th of September is another standout. The morning is marginal with 10ft of ESE swell, but the afternoon goes glassy with the same size, 10-second period, and excellent conditions for experienced surfers. Energy is very strong (2389 to 2355). This is a big, clean swell for experts only—over 8ft is too much for beginners.

Information about the Robberg Surf forecast
The above surf forecast table for Robberg provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Robberg can be found by selecting the local surf guide option on the grey menu. Our Robberg surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Robberg) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Robberg may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
