The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the cards for Super Tubes over the next couple of weeks. It’s a bit of a mixed bag, so we need to pick our moments.
The pattern kicks off with some small, messy swell. The first real glimmer comes later, but you’ll have to be patient. There’s a long stretch of poor conditions mid-period, but a proper standout window arrives in the second week.
First up, Saturday the 12th is a non-starter. We’ve got a weak 4ft WSW swell, but with a light cross-onshore breeze and the water feeling much colder than normal at 60°F – that’s 6°F colder than average, which is very unusual for this time of year. Combined swell energy is only 787 (moderate), so it’s pretty unexciting. Not worth paddling out.
Sunday the 13th looks worse. Swell bumps up to 8ft from the SW, but a fresh cross-onshore wind ruins it. The energy jumps to 2307 (strong), but the surface is lumpy and choppy. Avoid.
Monday the 14th morning is still average with onshore wind and 4ft swell. However, Monday afternoon shows some promise. The wind swings to a light offshore from the WSW, and with a 4ft SW swell, period 12 seconds, it’s clean. Combined energy is 502 (moderate). Not huge, but clean conditions make it worth a look for a fun session.
Tuesday the 15th is better. Morning has a light offshore breeze from the WSW, 4ft SW swell, and clean conditions (474 moderate energy). Afternoon stays clean with a light cross-offshore breeze, swell picking up to 5ft, period 10 seconds (570 moderate energy). This is a solid, user-friendly day.
Now, the standout. Wednesday the 16th morning is the pick of the forecast. We’ve got a 10ft SW groundswell with a period of 14 seconds, delivering 3287 combined energy (strong to very strong). That’s serious power. The wind is light offshore from the WSW, so conditions will be clean and groomed. This is only for experienced surfers – 10ft is big. Super Tubes is a reef and point, so the long-period swell will really line up nicely. This is the session to circle.
Wednesday afternoon still has 8ft SW swell but the wind goes cross-shore, making it less clean. Still decent for the crew who can handle it.
From Thursday the 17th right through to Monday the 23rd, conditions deteriorate. Persistent cross-onshore winds and choppy surf make for poor quality. There’s still swell – 6ft to 8ft – but the wind kills it. This stretch is a write-off for paddle surfing. If you’ve got a kite, the strong cross-onshore wind and solid swell could be fun, but for a surfboard, forget it.
Tuesday the 24th offers a glimmer. Morning has 6ft SW swell (period 14 seconds) with light cross-onshore breeze. It’s marginal but improving. The energy is 1103 (strong). Afternoon sees the wind go cross-offshore, making things cleaner, but still a bit hit-and-miss.
Wednesday the 25th morning stays clean with a cross-offshore breeze, but the swell drops to 3ft. Afternoon is the better bet: 3ft SW swell, 13 seconds period, gentle cross-offshore breeze, clean conditions. Combined energy is 503 (moderate). Small but clean – good for a longboard.
From Thursday the 26th, the swell fades right down and the wind turns onshore again. The final entry on Sunday the 27th afternoon shows a 3ft SW swell with a very long 19-second period, but cross-onshore breeze keeps it marginal. Combined energy is 942 (moderate). For a reef like Super Tubes, that long period could still produce a few clean lines, but don’t expect much.
So the big winner is Wednesday the 16th morning – that’s the one to set the alarm for. Tuesday the 15th is your backup for smaller, cleaner waves.
Stay patient, stay stoked.

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.
