The Lowdown
Alright, let's get into it. The only spot we’re looking at is Super Tubes. A reef and point wave that’s very consistent and likes a good SW swell. Advanced surfers only – this isn’t a learner’s wave.
The forecast starts on Monday August 10th. There’s swell, but it’s not pretty. Monday morning has a 2.5m SW swell with a 12-second period, and a cross-off wind from the south at 20 km/h. The water is a chilly 58°F, which is about 8°F colder than normal – that’s a huge anomaly. The wave energy is strong (1776). By the afternoon, the wind goes cross-shore and it gets choppy. Not worth it.
Tuesday the 11th and Wednesday the 12th are total washouts with onshore winds. So there’s a gap until Thursday the 13th. Thursday morning has some life – a 1.6m SW swell with a long 16-second period, and a light offshore from the NE at 10 km/h. Energy is strong (2033). It’s rated as marginal though, not quite pumping. Thursday afternoon turns onshore again.
Friday the 14th morning has a 1.4m SW groundswell (16 seconds) with a light cross-shore, and energy is moderate (942). It’s okay but not special. The weekend is mostly average, but late Sunday the 16th afternoon gives us a clean, light offshore from the SW at 20 km/h with a 1.2m SW swell. Small but clean.
Now for the real highlight. Monday August 17th is the day. Monday morning: 1.7m WSW swell, 13-second period, clean offshore wind from the WSW at 20 km/h, strong energy (1518). That’s excellent for experienced surfers. Monday afternoon gets even better: 2.3m SW swell, 16-second period, light cross-offshore wind, and huge energy (2653). That’s the peak of the whole outlook – clean, long-period, powerful. Tuesday the 18th holds that quality with a 2.1m SW swell in the morning and 2.0m in the afternoon, both with clean offshore winds.
Then it fades. Wednesday the 19th and Thursday the 20th are poor with onshores. Friday the 21st is messy. Saturday the 22nd offers a surprise: a 1.7m SE swell with a short 9-second period, but offshore from the WSW at 10 km/h and clean. Different direction and shorter period, but clean conditions make it rideable.
The final week is mostly a bust, except for Sunday the 23rd morning which is blown out by a 40 km/h offshore wind – good for kiting. There’s a massive swell on Monday the 24th and Tuesday the 25th (3.0m to 3.5m), but with strong onshore winds, it’ll be a messy, dangerous beast. Only for the hardcore.
The best call is Monday the 17th and Tuesday the 18th of August at Super Tubes. If you’re an advanced surfer and you want clean, powerful waves, that’s your window.

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.
