The Lowdown
Alright folks, it's Rusty here. Let's have a look at what's on the menu for Robberg over the next couple of weeks.
The pattern is a bit of a mixed bag. We've got a solid run of swell but the wind is going to be a real pain for most of it. The water is a serious talking point – it's sitting at 57°F but that's almost 7°F colder than it should be for this time of year. That's a wild anomaly, so you'll be needing a thick steamer and maybe some booties if you're heading out.
The first couple of days aren't really worth your time. On Tuesday the 1st, we've got a 8ft SW swell but the wind is cross-on, making it messy. The wave energy is strong (2314), but it's not doing us any favours. Wednesday and Thursday look just as average with onshore winds and rain, and the swell gets a bit jumbled up.
Friday the 5th and Saturday the 6th are write-offs. The wind is howling from the east, creating a lumpy, choppy mess. The swell is small and the energy is weak (684 down to 596). Not worth paddling out for.
Now, here's the first real standout. Monday the 7th morning is looking very promising. We've got a clean 7ft SW groundswell, with a period of 14 seconds, and the wind is a light cross-offshore from the north-northeast. The combined energy is strong (2664). This is a solid, powerful wave for experienced surfers. The swell is over 8ft, so this is for the crew who know what they're doing. The period is long, so at a beach and reef setup, it might be a bit straight, but that clean wind will make it worth a look. Crowds are sometimes a thing here, so you might have some company.
After that, the swell backs right off. We're looking at tiny, weak waves from the 8th right through to the 10th. Nothing to get excited about.
Then we get another chance. The 11th and 12th are a bit average, but the morning of the 16th of September has a big 7ft SW swell sliding in with a very long period of 17 seconds. The energy is huge (2794). The wind is cross-on though, which is a shame. It'll be choppy, but for a powerful, long-period groundswell, the raw energy is there. This is promising but a long way out, so keep your fingers crossed.
The Best on Offer: Honestly, Monday the 7th morning is the clear winner. Clean, offshore wind and a solid SW groundswell. That's the one to circle on the calendar. The 16th of September has the size and period, but the wind is a worry.
"That's it from me. Keep an eye on the wind and don't forget the extra rubber. Rusty out."

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.
