The Lowdown
Hey everyone, Rusty here.
Alright, Robberg outlook: we’ve got a solid 16-day run, with a big standout coming up. First good action is Monday morning, September 14th. We see an ESE groundswell at about 8 feet with a 10-second period, combined energy around 1657 – nice push. Water temp is 59°, which is much colder than average for this time of year – a -3° anomaly, so bring the thick rubber. Wind is glassy calm from the NNE, so it’ll be clean and smooth for those who can handle it.
Tuesday the 15th has a smaller 5-foot east swell at an 11-second period, glassy winds in the morning again – good for intermediates. Crowds are only sometimes here, so it’s mellow.
Wednesday the 16th sees a big 10-foot SW groundswell with a very long 14-second period, combined energy jumps to 3147 – that’s strong. Cross-off winds from the WNW at 12 mph keep it clean, but this is expert-only territory. Afternoon gets onshore and messy.
Thursday and Friday are blown out with cross-shore winds and lumpy conditions – skip those.
The absolute standout is Sunday, September 20th. Early morning we get a 12-foot ESE swell with an 11-second period and combined energy at a huge 5218 – very strong. Winds are glassy light from the WSW at 3 mph. That’s exceptional, clean, heavy surf for experts only. Afternoon goes to crap with heavy rain and a strong cross-onshore.
After that, there are a few clean-ish mornings like the 25th with a 6-foot east swell and cross-off winds, but nothing matches that Sunday.
So if you’re a solid surfer, the 20th is your day. Otherwise, pick the glassy mornings and hope for the best.
Rusty.

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.
