The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up at Super Tubes over the next couple of weeks.
Right off the bat, we’re looking at a bit of a slow start. Tuesday the 11th has some waist-to-chest high swell (8ft) out of the SSW, but the wind is a messy cross-onshore – lumpy and choppy, honestly not worth paddling out for. The water is running at 57°F, which is a whopping 9°F colder than average for this time of year, so it’s gonna feel seriously chilly. Wednesday the 12th and Thursday the 13th are pretty much a write-off too, with onshore wind ruining things despite some decent long-period groundswell in the water.
Friday the 14th stays marginal. The wind is still cross-onshore, and those 15-second period SW swells are just not making the most of the conditions here. You’re better off waiting.
Now, Saturday the 15th is where it starts to turn. We get a glassy morning with a clean 4ft SW swell. It’s small but that glassy surface is gold. Then Sunday the 16th picks up with a fresh offshore wind all day – morning is WSW at 19 mph, afternoon calms a bit. Clean lines on a 4ft swell.
But here’s the standout: Monday the 17th. That is your day. Glassy zero wind in the morning on a solid 6ft SW swell, and then a gentle offshore breeze in the afternoon keeping it smooth. This is the best all-round session of the first week – chest to head high, clean, and that reef-and-point setup at Super Tubes (South Africa) will be working nicely with the long-period energy.
Tuesday the 18th afternoon brings a legit pulse: 10ft SW swell with a moderate offshore wind. That’s big, that’s for experienced surfers only, but if you can handle it, it’s gonna be pumping with a combined wave energy of 2879 – strong, powerful lines. Wednesday the 19th stays solid with offshore winds and 10ft to 7ft SW sets.
Looking into the second week, things get a little wild. Thursday the 20th morning is glassy with 5ft SW swell, but it’s not the main event. The real monster is brewing for Saturday the 22nd. We’re looking at an 12ft to 13ft SW groundswell with a very long 16-second period on the afternoon pulse. Combined energy hits 7514 – that is massive. The wind is strong offshore (WSW, 25 mph), so it will be clean but incredibly powerful. Only the experts should even think about it, and expect long lulls between sets. This is a beast of a day.
Sunday the 23rd and Monday the 24th see the swell drop back, but the glassy morning on Monday the 24th (5ft SW) will be a nice clean reset. Tuesday the 25th morning is also glassy with 6ft SW. Then Wednesday the 26th morning brings another glassy 7ft SW swell – excellent conditions for experienced surfers.
There are no real gaps with zero surf here, but plenty of days where the wind is just wrong. Keep your eyes on Monday the 17th for the classic session and Saturday the 22nd for the big-wave grunt. Crowds at Super Tubes can be often, so get out early on those mornings when it’s glassy.
Stay stoked.
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.
