The Lowdown
Alright folks, Rusty here. Let’s get into it for this stretch. We’ve only got one spot on the radar for the next 16 days, and it’s a classic.
The main event is Super Tubes, a reef and point setup that’s very consistent and handles a good SW swell. Looking at the whole run, there are glimmers of absolute magic, but the wind is going to be a real battle for most of the period. The water temperature is sitting at 57°, which is a massive 9° colder than normal for this time of year. That’s a proper shock to the system, so bring a thick steamer.
The first real standout is Thursday afternoon, the 10th of September. We’ve got a solid 7ft swell rolling in from the SW, with a very long period of 16 seconds. That’s proper groundswell and it’s firing straight into this break. The wind is a moderate offshore breeze from the SW, keeping it clean. The combined energy is pumping at 2155 (moderate-to-strong energy). This is going to be a heavy, powerful wave for experienced surfers only; at 7ft with that period, it’s a handful. The crowds are a potential issue here as it’s often busy, but with that quality, you’ll have to deal with it. This is the best on offer.
The next morning, Friday the 11th, drops a little to 6ft with a 13-second period, but the wind goes light and cross-shore from the SE. It’s clean-ish, but the call is marginal. The afternoon goes to crap with a strong cross-onshore. Saturday the 12th is a write-off with onshore winds, even though there’s a 6ft swell in the afternoon with a 15-second period. Sunday the 13th is a total loss with fresh onshore winds and light rain.
We get a little reprieve on Monday afternoon, the 14th. The swell drops to 4ft, but the wind swings offshore from the W at 30 km/h. It’s a fresh offshore, so it’ll be clean but bumpy. The energy is weak (451). It’s a marginal call.
Now, Tuesday the 15th is a hidden gem. Morning and afternoon both look good. The swell is 5ft (12-second period) in the morning, dropping to 4ft (10-second period) in the afternoon. Wind is light and cross-offshore from the NW and SSW, so the surface will be clean. This is excellent for a longboard or a funboard. The energy is low (558-590), so it’s not a pit, but it’s a great, user-friendly wave.
Then we get a serious pulse on Wednesday the 16th. The morning sees 7ft with a 16-second period and a clean cross-offshore wind. The energy jumps to 3389 (strong). The afternoon gets even bigger: 12ft from the SW with a 15-second period, and the energy is a massive 4949 (very strong). The wind is still cross-offshore. This is only for experts. The call is marginal, but that’s likely due to the heavy size and potential for closeouts on a beachy setup. This is a big, big day.
The rest of the week into the next is a long stretch of poor surf. From Thursday the 17th right through to Wednesday the 23rd, it’s all onshore winds, choppy conditions, and poor surf quality. There are a few small windows, like the morning of Tuesday the 15th and the 24th of September, which is the last bit of hope in the second week. The 24th has a clean 4ft swell with light cross-offshore winds, but the energy is low (563-450). It’s a small, clean day for a quiet session.
Other than that, the second week is mostly a bust. The strong offshore winds on the 25th of September (Friday) are too strong (35 km/h) and the swell is tiny (3ft), so don’t bother.
Bottom line: If you’re an expert, Thursday the 10th and Wednesday the 16th are the heavy hitters. Tuesday the 15th is the best bet for a clean, fun session without the crowds of the big days. The rest is a long gap of blown-out frustration.
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.
