The Lowdown
Alright, Rusty here. Let's get into it.
Alright, grab your coffee (or something stronger) 'cause we've got a full slate ahead. For the next few weeks, it's all about one spot: Super Tubes. This place is a reef and point setup, consistently handling the swell, making it the main game in town. Don't be fooled by the first day, August 15th – that Saturday sees some weak energy and cross-onshore wind, so give it a miss. The water is a frigid 53°F, which is a whopping 13°F colder than average for this time of year. That’s not just a little bit cool, that’s a "bring a thick steamer and maybe a thermos" kind of cold.
Things kick off proper on Sunday morning, August 16th. We’ve got a clean 5ft SW groundswell rolling in, with a light offshore wind. The wave energy is ticking up (529 to 769). It's nice, but not the peak.
But hold on to your boards. The real standout is Monday, August 17th through Thursday, August 20th. This is a solid block of premium surf. A solid 7ft to 10ft SW groundswell, with a period between 12 and 14 seconds. The wind is offshore or clean cross-offshore for most of these days, keeping the surface smooth as glass. The combined swell energy is massive, hitting over 2500 on the 20th. This is expert-level territory; the waves are powerful, well-shaped, and hold up perfectly on this point and reef set-up. Crowds are "often" at Super Tubes, so with conditions this good, expect some company in the lineup. Paddling out might be a chore with those long gaps between sets, but the walls you get will be worth the wait.
There’s a hiccup on Friday, August 21st. The wind swings onshore from the east and the surf gets chopped up. Poor conditions, so sit that one out. Saturday the 22nd and Sunday the 23rd see a huge spike in swell, pushing 12ft to 13ft from the SSW with a very long 13 to 14-second period. The wind goes fresh offshore, so the face will be clean, but this is big, serious ocean. The combined energy readings are off the charts (over 6600). This is strictly for the experienced crew; too big for intermediates, and the raw power will be intense.
The energy tapers through the following week, from the 25th to the 27th, with lots of cross-onshore wind and more marginal conditions. Not much to write home about.
Looking ahead to the end of the forecast window, another window opens up. Friday, August 28th and Saturday, August 29th bring another strong push of 7ft to 8ft SW groundswell, with a very long 15-second period. The winds are offshore or cross-offshore, so the quality should be excellent for experienced surfers again. It’s a promising end to the run, but it's a way off yet, so don't book your flights on it. The last day, Sunday the 30th, still has some decent 7ft swell but the wind is blowing fresh, making it a bit of a wild card.
Overall, the absolute best of the best are Monday the 17th through Thursday the 20th, and then the final weekend of the 28th and 29th. Get out there and earn your noodles.
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.
