The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the cards for the only spot that’s really worth paddling out for in this stretch.
We’re looking at a mixed bag for the next couple of weeks, with a definite standout window that’s going to get the stoke levels up. The water is currently sitting at 58°, which is a massive 9° colder than usual for this time of year. That’s way more than just a bit chilly – it’s an unusual cold snap, so you’ll want a thick suit and booties if you’re heading out.
Super Tubes is where the action is, and it’s a reef and point setup that handles the swell well. It’s very consistent and gets offshore in a WSW wind, with the best swell direction coming from the SW. The crowds are often there, so don’t expect a solitary session.
The first few days are pretty rough. The onshore wind is slamming it, and the swell is short and messy. Wednesday the 12th and Thursday the 13th are write-offs with strong onshores, and the combined energy is high (1084 to 2117) but it’s all blown out. Friday the 14th is still marginal at best with a cross-shore wind.
You’ll start to see a real shift on Saturday the 15th morning. The wind drops to glassy, and we’ve got a clean 4ft SW groundswell rolling in with a 14-second period. The energy is around 539, which is moderate, but that glassy morning makes it a real treat for a fun, clean session. The afternoon gets a light cross-onshore, so get out early.
Sunday the 16th afternoon is another sneaky good one. The wind swings offshore from the SW, cleaning up the 4ft WSW swell. Again, it’s not huge, but that offshore wind makes it super clean.
Now, the real standout window starts on Monday the 17th morning. The wind is glassy, and we’ve got a solid 5ft SW groundswell at 14 seconds. The energy jumps to 920 (moderate), and the conditions are set for some very good, clean waves. This is a proper session for the experienced crew.
The next day, Tuesday the 18th morning, is another cracker. We’ve got a moderate offshore wind from the WSW, cleaning up a 6ft SW groundswell. The energy is pushing 996, and it’s going to be clean and powerful. This is the best of the first week.
But the real big one for the experts is Wednesday the 19th. The morning is still good with a 10ft SW swell and a moderate offshore, but the afternoon is where it gets epic. The swell drops to 10ft, period drops to 11 seconds, but the wind goes light and cross-off from the south. The combined energy hits 1767, and the report says it’s excellent for experienced surfers. This is big, powerful, and clean. If you’re not an expert, stay on the beach, because 10ft is well into the too-big-for-beginners zone.
After that, we get a bit of a lull. Thursday the 20th and Friday the 21st are blown out or marginal. The swell drops right off, and the energy is weak.
Looking further out, Saturday the 22nd shows a new pulse of 7ft SSW swell with a 14-second period, but the wind is light cross-shore. The energy is high (1975), but the wind isn’t perfect. It’s a promising option for the weekend, but not as clean as the earlier standout.
Sunday the 23rd is a no-go with onshore wind and a big 8ft swell that’s just going to be a wind-blown mess. The rest of the week into the 27th is mostly small, clean, and marginal, with a few 5ft SW swells and offshore winds on the 27th that will be fun for a smaller board.
Best on offer: The absolute standout has to be Monday the 17th morning for that glassy, clean 5ft SW groundswell, and Wednesday the 19th afternoon for the big-wave crew looking for a powerful, clean 10ft SW groundswell with light wind.
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.
