The Lowdown
Alright folks, Rusty here with a look at what’s shaping up at Tubes over the next couple of weeks. We’ve got a bit of a slow start, but some absolute belters lined up later on, so don’t write this window off.
The first few days are pretty average. Tuesday morning the 8th kicks off with clean, glassy conditions and a clean 4ft SW groundswell (period 13 seconds) rolling in. The water is a chilly 60°, which is a whopping 6° colder than normal for this time of year – that’s seriously unusual, so you’ll want a thick suit. The combined energy is moderate at 695. It’s surfable, but it’s not going to set the world on fire. By Tuesday afternoon, it gets messy with a cross-onshore breeze, so that early session is the only call there.
Wednesday the 9th is pretty poor with cross-shore winds, and Thursday the 10th sees the wind swing offshore. Thursday afternoon is actually a standout early in the run: a clean 7ft SW groundswell (16 seconds) with gentle offshore wind. Combined energy hits 1991, that’s moderate to strong energy. The period is long, which is great for a reef and point setup like Tubes – expect well-shaped, powerful lines with long lulls between sets. This is the best session of the first week.
Friday the 11th into Saturday the 12th is a mixed bag. Saturday morning has clean, light cross-offshore wind and a 4ft swell, a nice little window. Sunday the 13th sees the swell bump up to 7ft, but cross-onshore wind spoils it. Monday the 14th afternoon has a clean offshore wind again on a 4ft SW swell (568 combined energy) – good for a smaller board session if you’re keen.
Now, for the real deal. We’ve got a big gap of poor conditions from Tuesday the 15th, with onshore and cross-onshore winds ruining the shape. But then, hang on. Wednesday morning the 16th is where it gets serious. We’re looking at a solid 10ft SW groundswell (18 seconds!) with a clean, cross-offshore breeze. The combined energy is a very strong 5462. This is big, powerful, long-period groundswell. At over 8ft, this is expert territory only. It’ll be a fast, heavy reef and point break. Thursday the 17th morning is another absolute gem: glassy conditions, 8ft SW swell (15 seconds) and combined energy of 3234. That is a dream session if you can handle it. Thursday afternoon gets even bigger with a 15ft S swell, a different direction, but still clean.
Friday the 18th and Saturday the 19th keep the size up with excellent offshore winds. Saturday morning the 19th has a clean 8ft ESE swell with moderate offshore wind – still very strong energy at 2772. Another top tier session. The weekend and into the following week do drop off in quality, with strong cross-onshore winds and chop returning by Sunday the 20th and beyond.
So, the standout of the whole outlook is hands-down Thursday morning the 17th at Tubes. Glassy, 8ft of long-period SW groundswell, massive energy. That’s the one to circle. Wednesday the 16th morning and Saturday the 19th morning are the other big winners. Get on it.
Rusty.

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.
