The Lowdown
Alright, let’s talk Super Tubes. This is a reef and point break that loves a solid SW groundswell. Water temp is about normal for this time of year. The start of the run is a bit weak. Thursday the 13th has a clean-looking morning with a long-period 4ft SSW groundswell, but the wind is onshore and the energy reading is massive at 2117 — that’s very strong wave energy — yet the conditions are described as marginal. Thursday afternoon gets worse with a 6ft SW swell but poor surf. Friday the 14th stays below par, with light cross-shore winds and a 5ft to 4ft SW swell, energy dropping into the 900s. You’ll want to wait.
Saturday the 15th morning is where things start to flicker. It’s glassy, dead calm, with a clean 4ft SW swell running on a 14-second period. Energy is moderate at 548, but those glassy conditions will make it smooth. Not a standout size, but if you want a cruisy session, that’s your window. Saturday afternoon gets choppy again.
Sunday the 16th afternoon is a real turn. The wind swings offshore from the SW at 12 mph, the swell holds at 4ft from the WSW, period 13 seconds, and it’s clean. Energy is 465, so moderate, but that offshore breeze will make the waves stand up nicely.
Now, Monday the 17th morning — this is a standout. Glassy conditions, a 6ft SW swell with a 14-second period, and energy jumping to 1058, which is strong. The wave comment says “expect very good surf conditions.” That’s the best of the first week. Get on it.
Tuesday the 18th morning keeps the run going: 6ft SW swell, offshore wind from the WSW at 12 mph, energy at 1110, and clean conditions. Tuesday afternoon sees the swell bump to 8ft from the WSW with offshore winds, but the comment flags it as marginal on the tide — still, that’s a lot of power.
Wednesday the 19th morning is the real standout for experienced surfers. 8ft SW swell, strong offshore wind from the SW at 16 mph, period 12 seconds, energy 1546 — that’s very strong wave energy. The forecast says “excellent surf conditions for experienced surfers.” This is the big one. Wednesday afternoon holds at 8ft from the SSW but the wind goes cross-offshore, so it’s still clean but a bit less perfect.
After that, Thursday the 20th and Friday the 21st drop off badly with onshore winds and poor quality. The swell fades to 2ft by Friday morning. There’s a bit of a lull.
Saturday the 22nd morning brings a 10ft WSW swell but with a short 7-second period and fresh offshore wind — that’s more of a windswell, messy and big. Only for experts, and even then, the short period makes it lumpy. Saturday afternoon improves with a 6ft SW swell, 14-second period, energy 2023 (very strong), and clean offshore wind.
Sunday the 23rd morning is another standout. 8ft SW swell, 13-second period, offshore wind from the WSW at 12 mph, energy 1942 — very strong. The comment says “excellent surf conditions for experienced surfers.” That’s the other big session to circle.
The rest of the second week trails off. Monday the 24th has marginal conditions, then from Tuesday the 25th onward the swell drops below 4ft with persistent cross-onshore winds. Wednesday the 26th afternoon is flat with 2ft and glassy, but barely surfable. Thursday the 27th morning sees a little bump to 4ft SW with offshore wind and clean conditions, energy 487 — a last chance for a small, clean wave before Friday the 28th morning brings a 7ft SW swell with a 15-second period and cross-on wind, making it a marginal, tricky option.
Best on offer: Monday the 17th morning for the glassy, strong 6ft SW swell, and Wednesday the 19th morning for the powerful 8ft SW swell with clean offshore wind. Sunday the 23rd morning is a close third.

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.
