The Lowdown
Alright, Rusty here. Let’s look at the next couple of weeks for Super Tubes.
The forecast is a real mixed bag. We start with some small, clean waves but nothing worth writing home about. The real standouts are tucked away at the back end of the window, and they look promising, but we’ve got a fair bit of rough weather to sit through first.
We start off on Tuesday the 15th. It’s not exactly firing. Tuesday morning sees a small 3-foot SW groundswell with a long 12-second period. The wind is offshore from the WSW, making for clean conditions, but the combined energy is weak (241). The water temperature is a chilly 61°, which is a huge 5° colder than normal for this time of year – that's very unusual, so you’ll want a good steamer. It’s a tough start, with scores that are just plain ordinary.
Tuesday afternoon offers a bit more size at 4 feet, but the wind swings SE and goes cross-onshore, turning it messy. A small bump in energy (399) isn't enough to save it.
The highlight of the first week has to be Wednesday the 16th. A solid 10-foot SW groundswell rolls in, with a long 14-second period. The wind is offshore from the W in the morning, keeping the reef and point setup at Super Tubes clean. The wave energy is pumping hard (3869). This is serious size though – over 8 feet, so this one is for the experienced crew only. It’s easily the best of the early run.
The rest of that week and into the next turns nasty. From Thursday the 17th through to the end of the weekend, we get onshore winds and rain. The swell stays in the 4-foot to 8-foot range, but the conditions are poor to marginal. It’s a real write-off for a clean surf.
There is a brief window on Monday the 21st where conditions become clean again under a light cross-offshore breeze, but the swell drops to around 6 feet to 6 feet. It’s rideable but nothing spectacular. Then we’re back into a poor run of easterly winds and lumpy conditions from Tuesday the 22nd through to Thursday the 24th. A four-day blank run for any quality surf.
Now, here’s the long-range potential. The window starting Friday the 25th and into the weekend of the 27th and 28th looks really interesting. Friday afternoon the 25th sees a big 12-foot SW swell, but with a shorter 10-second period. The wind is a fresh offshore from the WSW, keeping it clean, with energy at 2523. That’s big, powerful, and raw.
But the true magic might be on Saturday the 26th and Sunday the 27th. On Saturday afternoon, a 6-foot SW groundswell with a solid 14-second period combines with a moderate offshore wind from the WSW. The energy is still strong (2172) and the description mentions excellent conditions for experienced surfers.
Then Sunday morning the 27th looks like a dream: a glassy 5-foot SW groundswell with that same long 13 to 14-second period. Combined energy is still well into the strong range (1466). That’s the morning to circle on your calendar. Glassy conditions and a long-period groundswell at a reef and point – it should be peeling perfectly.
After that, the surf starts to fade and the winds turn onshore again, so that Sunday morning session is the clear standout of the entire run. It’s a fair way off, so don’t book your flights yet, but it looks beautiful.

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.
