The Lowdown
Alright folks, Rusty here with a look at what Tubes has got cookin' for us over the next couple of weeks. Gotta be honest, the start of this run is a real bummer. We're looking at a big gap of nothing but junk for the first few days.
We're pretty much on hold until Saturday the 15th. Before that, the wind is just cruel – strong cross-onshore E'ly and ENE'ly breezes tearing up what little swell is around. The wave energy is all over the place but the quality is zero. There's a massive 2467 (strong) energy reading on Tuesday the 11th with a 8ft SSW groundswell, but with those 16 mph winds, it's just a mess.
But then, things get real. The first real standout window opens Saturday the 15th of August. The morning is the pick here. We've got clean 4ft lines rolling in from the SW with a sweet 14-second period. The real magic is the wind – a glassy 3 mph SW offshore breeze. This is gonna be clean, lined-up, and with that long period on a reef and point set-up, the shape should be excellent. The water temp is feeling about average for this time of year.
The quality holds through Sunday the 16th with clean, moderate offshore winds, but the swell dips a little. A bigger pulse builds again for Monday the 17th afternoon, with the swell jumping to 6ft at 13 seconds from the SW, and we get a glassy light offshore wind. This will be good but maybe a bit more powerful.
Now, let's talk about the true stand-out. Keep your eyes peeled for Sunday the 23rd of August. That afternoon session is the best on offer for the whole run. We've got a solid 7ft SSW groundswell with a period of 15 seconds, driving a combined energy of 2888 (very strong). But the wind is the hero here – a clean 9 mph SW offshore. For experienced surfers, this is gonna be excellent. The only caveat is that a long period swell like this at a beach might race, but at Tubes being a reef and point, it should set up perfectly.
Monday the 24th morning is also a gem, with clean 6ft SW swell and glassy conditions. There's another very promising window on Wednesday the 26th with a nice 4ft SSW groundswell (16 seconds) and gentle offshore wind.
So, it's a slow start, but once we hit the 15th, Tubes comes alive. The 23rd of August is the absolute king of the period. Be patient. It'll be worth the wait.
Rusty out.

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.
