The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at what we’ve got coming up.
We’ve got a solid run of surf on the cards, but it’s not for the faint of heart. The first real action kicks off on Sunday the 16th of August and it’s all about Super Tubes. This is a reef and point setup, and it’s very consistent, so you know it’s going to be working.
The water is a cool 53° – that’s a massive 13° colder than usual for this time of year, so you’re gonna need a good thick steamer. The anomaly is well over five degrees, so this is very unusual.
Sunday morning we see a 5ft SW swell, with a period of 13 seconds, that’s proper groundswell. The energy is moderate (854) and we’ve got a gentle offshore wind from the west. It’s clean. The afternoon holds similar size with a cross-off wind, still good.
Monday the 17th steps it up. The morning delivers 7ft SW groundswell with a 14-second period. The energy is strong (1788), and with a light offshore breeze from the WSW, it’s going to be excellent for experienced surfers. The afternoon stays strong with 8ft.
Tuesday the 18th is more of the same excellence. 7ft in the morning, building to 8ft in the afternoon, both with light offshore or cross-off winds. The energy is very strong, hitting 2063 in the afternoon.
Now, Wednesday the 19th is a standout. The morning is glassy, with a 8ft SW groundswell and a period of 13 seconds. The energy is pumping at 2132. The wind is nothing, just glass. This is as good as it gets. The afternoon gets a moderate offshore wind, but it’s still clean.
Thursday the 20th is for the big dogs. The morning has 10ft SW swell, and the afternoon hits 12ft. This is over 8ft, so it’s expert-only territory. The energy is enormous (3557 in the afternoon) with light winds.
Friday the 21st is another glassy morning, 8ft SW swell, 12 seconds period. The energy is still very strong (1952). The afternoon drops to 7ft with a gentle offshore. Perfect.
The weekend of the 22nd and 23rd gets a bit wild. Saturday the 22nd has a strong, fresh offshore wind (19-31 mph) that makes it very hard to paddle into, and the quality drops. The energy is moderate. Not a paddle day, maybe a kite day.
But Sunday the 23rd is the real standout of the whole run. The afternoon has a 13ft SSW swell with a 16-second period – that’s a very long period groundswell. The energy is exceptional (8583), and the wind is light and cross-off. This is a once-in-a-while type of swell at Super Tubes. It’s going to be huge, powerful, and perfect for experts. The morning is also solid at 12ft.
Monday the 24th still has massive 13ft SSW swell in the morning, glassy, but the energy is still exceptional (7830). The wind shifts onshore in the afternoon, making it messy.
The rest of the week into the next sees the swell drop but stay solid. The 26th of August has a 7ft SSW swell with a very long 18-second period, which is incredible for a reef like this, with a cross-off wind. It’s a long-range call, but it looks promising.
The final weekend of the 30th and 31st of August brings back the big stuff. The 30th has 12ft SW swell, but with strong offshore winds that make it a battle. The 31st of August is glassy in the morning with 12ft SW swell and a 15-second period, a good way to finish, but the afternoon gets a choppy cross-onshore wind.
Overall, the best on offer is the Wednesday the 19th glassy morning, and the absolute standout, the big one, is the Sunday the 23rd afternoon. That’s the one to circle on the calendar. It’s a long period, huge swell, clean conditions, at a very consistent reef. Expect crowds, because everyone will know about it.
Rusty.

Information about the Super Tubes Surf forecast
The above surf forecast table for Super Tubes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Super Tubes can be found by selecting the local surf guide option on the grey menu. Our Super Tubes 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 (Super Tubes) 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 Super Tubes 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.
Super Tubes is 19 km (12 miles) from the city of Kruisfontein. If you plan a holiday in Eastern Cape (South), look for hotels and other accommodation in Kruisfontein. Kruisfontein has rooms for a wide range of budgets as well as car hire and transport links.
