The Lowdown
Righto, let’s have a look at what’s coming. The first real call is Tuesday morning at Tubes, but after that we get a bit of a mix. The big news is the size arriving later – hold onto your board.
Tuesday the 25th of August kicks things off with a solid 8ft SW swell, period around 13 seconds. Combined wave energy is 3456 – that’s substantial. Wind is a moderate offshore from the WSW, so it’ll be clean. This is solid intermediate territory, and the water temp is a chilly 57°F, which is a whopping 9°F colder than normal for this time of year – far colder than usual, so you’ll want a thick suit. Tuesday afternoon stays clean with a 10ft SSW swell at 15 seconds, energy up to 4085.
Wednesday the 26th is a write-off – onshore E winds tear things up, 10ft swell but choppy and lumpy. Don’t bother.
Thursday the 27th is a beauty. Morning is glassy – no wind at all – with a 7ft SSW swell, period 12 seconds, energy 1563. That’s clean glassy conditions, a proper standout for the near-term. Afternoon gets a bit crossed up but still rideable.
Friday the 28th is small and weak – 4ft to 4ft, barely any energy, mostly poor. Saturday the 29th picks up again with some fun little 3ft to 3ft SW swell, offshore winds, clean but small.
Sunday the 30th sees a jump in size again: 10ft SW swell in the morning (energy 1052) but the period is only 8 seconds – short period, so it’ll be a bit lumpy. Afternoon is better with 8ft SW at 8 seconds, offshore winds, and energy 1197. Good for experienced surfers.
Monday the 31st offers a nice clean 7ft SW swell at 12 seconds, light offshore breeze, energy 1105 – another very good session.
Tuesday the 1st of September: morning clean with 5ft SW, period 11 seconds, energy 453. Afternoon builds to 8ft SW at 11 seconds, fresh offshore but clean. Good options.
Now, the standout of the whole window – Wednesday the 2nd of September. Morning at Tubes is exceptional: 16ft SW swell at 15 seconds, period over 15 seconds – very long period groundswell. Combined energy is 10216 – extreme. Wind is light offshore, glassy. This is for experts only, and it will be a true event. This break is a reef and point, so that long period will set up perfectly, not close out like a beach break. Afternoon stays big at 13ft, fresh offshore, still a monster.
Thursday the 3rd: 10ft SW, period 12 seconds, moderate offshore, energy 2779 – still solid but more manageable.
Friday the 4th of September: absolute bombs. 21ft ESE swell in the morning – energy 9925 – with moderate offshore wind. That is enormous. Afternoon 20ft SE, still clean. Again, experts only. The direction is ESE, while the optimum is SSW, but with that size and clean conditions, it’s still massive. This one is less certain being far out, but the promise is huge.
Saturday the 5th: 16ft ESE, but onshore winds make it choppy and poor. Sunday the 6th: 13ft ESE, onshore, poor to marginal.
From Monday the 7th, the swell drops right off – 4ft SW, then tiny, with poor conditions through the 8th and 9th of September. That’s the tail end of the window.
Bottom line: Thursday the 27th morning is your clean, glassy, mid-size gem. Wednesday the 2nd of September morning is the big one – enormous, clean, for experts only. Get on it if you’ve got the nerve.

Information about the Tubes Surf forecast
The above surf forecast table for Tubes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tubes can be found by selecting the local surf guide option on the grey menu. Our 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 (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 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.
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.
