The Lowdown
Alright, this is Rusty checkin' in from the coast.
Right now, it’s a bit of a slow start. We’ve got solid swell comin', but the first few days are a mess. Things clean up toward the end of the week, and there are some absolute bombs lining up for the weekend and beyond.
Tuesday afternoon is not the one. Super Tubes is seein' a 4ft SW groundswell, but with a cross wind, you’re just fightin' a chop. The water is 61°, which is about 5° colder than normal for this time of year – that’s a serious shift, so suit up. The energy is weak. Let it go.
Wednesday the swell jumps to 10ft from the SW with a 14-second period, which is proper groundswell. The morning has a cross-off wind, so it’s clean, but there’s some rain and the tide could mess it up. The energy is massive, but the call says it’s marginal. By the afternoon, the cross wind comes back. Hard skip.
Thursday is a write-off. Onshore wind all day from the ESE at 16 mph with 8ft to 7ft SW swell – just lumpy, choppy, horrible.
Friday same story. 6ft to 6ft SW swell but hammered by a fresh onshore breeze. Kite surfers might love it, but for us paddle folk, it’s a dud.
Saturday morning still onshore. But then look here – Saturday afternoon the wind drops to glass. 4ft SW groundswell (12 seconds) and flat calm. That’s a window. The energy is modest. If you want a longboard, this is your chance for a clean little wave.
Now, hold onto your board. Sunday the 20th is where it gets real. Morning sees 7ft SW groundswell at 14 seconds with glassy conditions. That’s excellent surf for experienced surfers. The energy jumps to moderate/strong. The afternoon holds 8ft with a light cross-off breeze, clean as. This is the first real standout. Super Tubes is a reef and point, so that long-period swell (14 seconds) will line up beautifully. It’s very consistent, but it’s also often crowded – expect company.
Monday the 21st the wind swings back onshore. Back to average.
Then we go into a bit of a lull. Tuesday through Wednesday morning (22nd and 23rd) the swell drops off to under 3ft. Small and weak.
But Wednesday the 23rd it cranks up again. A new pulse of 12ft from the WSW hits, but the period is only 10 seconds, so it’s a wind swell mix. The morning has clean cross-off wind, but the energy is still strong. The afternoon goes offshore from the WSW at 19 mph – clean, groomed faces. Another good one for advanced surfers.
Thursday the 24th looks like the biggest day of the entire forecast. We’re talkin' 13ft SSW groundswell with a 13-14 second period. The combined energy is massive – 4399 in the morning and a whopping 6587 in the afternoon. The wind is offshore or cross-off, so the sets will be clean and lined up. This is for experts only – over 8ft and powerful. If you’ve got the skills, Thursday afternoon is one of the best bets of the whole 16 days. The paddle out will be a mission.
Friday the 25th morning is glassy again, 10ft SW at 14 seconds. Excellent for experienced surfers. The afternoon gets a bit choppy.
And then we have our final, maybe best, window. Saturday the 26th and Sunday the 27th. Saturday sees 12ft SW groundswell (13 seconds) with moderate offshore wind. The energy is very strong. Sunday morning holds 12ft SW at 14 seconds with gentle offshore wind. Clean, powerful, and big. The energy peaks at 4691. This is a true standout run for the second week.
After that, Monday the 28th drops to 7ft with a light cross wind – marginal. The rest trails off into small, weak surf.
So if you’re pickin' your moments: Sunday the 20th is the first real gem, and Thursday the 24th and Saturday/Sunday the 26th-27th are the heavy-hitters. The crowds will be there, so get in early.
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.
