The Lowdown
Howdy, Rusty here. We’ve got a solid run of surf coming up at Super Tubes over the next couple of weeks. This is a reef and point setup that handles SW swell well, and there’s plenty of action on the way. Right now, things start a bit rough – Wednesday the 12th is a write-off with strong onshore winds and messy conditions. Thursday morning the 13th sees a 4ft SSW swell with a ridiculous 20 second period, but onshore wind keeps it marginal. Not the time to paddle out.
Friday the 14th is still cross-onshore and choppy, nothing to write home about. Then we get a little window: Saturday morning the 15th, the wind goes glassy, with a 4ft SW swell at 14 seconds. Very clean, but the combined energy is only 535 – weak. It’s more of a longboard glide than a proper session. Sunday the 16th picks up with a cross-off breeze in the morning and a clean 4ft WSW swell. By the afternoon it’s offshore, moderate wind, still 4ft but the energy is still low at 465. Good for a cruise.
Monday the 17th is onshore slop again, forget it. But then we get a proper standout. Tuesday the 18th afternoon: offshore wind from the WSW at 25 km/h, 5ft swell, period 13 seconds, combined energy 772 – moderate. The report says “expect very good surf conditions.” That’s the first real quality session of the forecast. Clean, offshore juice.
Wednesday the 19th afternoon holds up with a 6.6ft SW swell at 11 seconds, a bit shorter period but still clean under cross-off breeze. That’s a solid day, but watch the size – 6.6ft is pushing into expert territory.
Now for the big one. Friday the 21st morning: 7.9ft SW groundswell, 13 second period, offshore wind at 20 km/h, combined energy a whopping 1874 – strong. “Excellent surf conditions for experienced surfers.” That’s an absolute standout. Saturday the 22nd is even more powerful: 8.2ft SW swell at 13 seconds, 2255 combined energy, moderate offshore breeze – glassing off. Another excellent day for crew with skill. The 22nd morning is likely the best of the whole run – big, clean, powerful. Keep in mind, anything over 8ft is experts only. That’s a heavy lineup.
Sunday the 23rd drops back to 9.8-11.5ft SSW, but that’s with onshore or cross-onshore wind and a shorter 11-12 second period. Messy and maxing out. Not ideal.
Monday the 24th afternoon cleans up again: 6.6ft SSW, offshore wind, 1354 combined energy – excellent conditions. Tuesday the 25th morning is glassy, 5ft S swell at 13 seconds, 897 energy – very clean. Nice recovery.
Wednesday the 26th is a weird one: 7.9ft WSW but with a terrible 7 second period. That’s windswell, not a proper wave. The 27th morning drops to 1.6ft SW with an 18 second period, 345 energy – clean but tiny. That’s the tail-off.
Water temp is about average for this time of year, nothing unusual to report.
Best on offer: Tuesday 18th afternoon for the start of the clean fun, and then the Friday 21st through Saturday 22nd stand well above everything – big SW groundswell, clean offshore wind, and serious energy. Get on it.

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.
