The Lowdown
Alright, grab your board and listen up. Rusty here with a long-range look at the only game in town.
We’re looking at Super Tubes, a reef and point setup that’s very consistent and known for handling a good SW swell. It’s an advanced wave for good reason. The water is sitting at a very unusual 53°F, which is far colder than average for this time of year, so you’ll want a good hood and gloves.
The surf kicks off on Sunday, August 16th, with a clean 5ft swell from the SW at a solid 12-second period. The cross-off wind is only 9 mph, so it’s rideable, but the energy is moderate (718). This is more of a warm-up.
Now, Monday, August 17th, through Wednesday, August 19th, is where it starts to get really good. Monday morning is the real standout of the first week. You’ve got a clean, offshore SW wind at just 3 mph, grooming a 8ft SW swell with a 14-second period. The energy jumps to 1886, and the conditions are described as excellent for experienced surfers. This is the window for early sessions. Monday afternoon and Tuesday (August 18th) stay clean with similar swell size and solid 13-second periods. By Wednesday morning (August 19th), the swell hits 10ft with a 13-second period, a clean cross-off from the NW at only 3 mph, and the energy is strong (2407). This sets up beautifully for the reef.
Keep your eyes on Thursday, August 20th. This is a serious standout for the deepest part of the week. Both morning and afternoon deliver a clean 13ft SW groundswell with a very long 14-second period. The energy is well into the strong range (5164 to 5241), and conditions are excellent for experts. This is pure power, and with offshore or cross-off winds under 9 mph, Super Tubes will be lighting up. This is for experienced surfers only – too big for anyone else.
Friday, August 21st, is a write-off. Onshore winds mess it up, so give it a miss. Saturday, August 22nd, offers a clean, fresh offshore wind but the swell drops. The morning has a smaller 5ft, and the afternoon jumps to 10ft but with a short, weak 7-second period. It’s not the same quality.
Then comes a huge, powerful pulse. Sunday, August 23rd, and Monday, August 24th, see a massive SSW groundswell with periods of 14 to 15 seconds. Sunday peaks at a huge and very dangerous 20ft, with extremely strong energy (16,355). The wind is strong offshore at 19 to 25 mph. This is for the absolute elite only and will be hard to paddle into. Monday brings a still-massive 16ft to 15ft, and the energy is extremely strong (9,210). It’s cleaner, but still a big, expert-only ocean.
The end of the month from August 27th onwards sees the energy back down, with clean 5ft to 8ft SW swells and fresh offshore winds. It’s consistent, but nothing compared to that mid-period peak. Another big pulse shows up on Monday, August 31st, with a 13ft SW groundswell and a 15-second period, but easterly winds are onshore and choppy, which will ruin the lineup.
Bottom line: The best windows are Monday morning, August 17th, for a clean, solid session, and Thursday, August 20th, for a powerful, clean, expert-level day. Be ready for the huge stuff on the 23rd and 24th if you’re charging, but don't take it lightly.
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.
