The Lowdown
Alright folks, this is Rusty, and we’ve got a look at a single spot for the next couple of weeks. This is a deep dive into Tubes, and it’s a wild ride ahead.
We start off with a bang. Monday, August 24th, we’re straight into it. The morning is looking sweet with a clean 7 ft SSW groundswell – that’s a 12-second period, meaning proper waves. The water is a chilly 58°, which is a massive 8° colder than normal, so you’ll want a thick steamer. The combined energy is strong at 1099, and with light offshore winds, it’s going to be a clean, lined-up session. The afternoon drops a touch in size to 4 ft from the SSW, but the period stretches to 14 seconds and the energy jumps to 1378, still glassy with the wind. A solid day.
Tuesday, August 25th, is a step up. The morning brings 8 ft SW groundswell with a 13-second period, and the energy is pumping at 3456. Light offshore wind keeps it clean. This is getting into the territory where you want to be confident. The afternoon is even bigger: 10 ft SW at 15 seconds, with energy at 4132 and a gentle offshore. This is expert-level territory, but it’s pristine.
Then, Wednesday, August 26th, is a write-off. The wind howls onshore from the east at 18-22 mph, ruining the 10 ft swell. It’s lumpy and messy. A complete no-go.
Thursday, August 27th, is a mixed bag. The morning wind is onshore, making the 7 ft SSW swell a bit of a question mark. But the afternoon turns it around – a light cross-off breeze and a clean 6 ft SSW swell makes for a good, fun session.
Friday and Saturday, August 28th-29th, are poor. Small, weak swell with onshore and cross-shore winds. The energy drops to the 400-500 range, and it’s just not worth it.
Now, Sunday, August 30th, is a hidden gem. We get a bit of a reset. The morning is clean with an 8 ft WSW swell, but the period is short at 7 seconds. The real magic is the afternoon: glassy conditions, 12 ft WSW swell, and the energy is back up to 1415. This is a standout session for anyone who can handle the size.
Monday, August 31st, sees a big swell (8 ft) but the wind is a strong offshore at 25 mph. The waves will be clean, but paddling into them will be a battle. Only for the strong and committed.
The first week of September is where things get wild. September 1st is small and choppy. September 2nd brings a massive groundswell, building from 15 ft to 18 ft SW, but the wind is cross-off, keeping it clean. The energy is colossal – 5201 to 8833. This is only for the most experienced.
The real standout of the entire forecast is September 4th. The swell maxes out at a solid 20 ft SW with a 15-second period, and the energy is astronomical at 16211. The wind is light and offshore, turning this into a world-class, clean, giant wave session. This is an expert-only, life-changing day if you can handle it. The day before, September 3rd, has similar size but with a gale-force wind, so it’s a mess.
The energy holds through the 5th and 6th, but the wind turns gnarly again on the 5th with a near-gale. The 6th, September 6th, is a much better proposition with a gentle offshore and 8 ft SSW swell, offering a great day for skilled surfers.
The forecast ends on a whimper. September 7th and 8th are blown out by strong onshore winds, leaving us with no surf of note.
To sum it up: The best of the best is the 20 ft, glassy, offshore swell on Friday, September 4th. That’s the one you circle on the calendar. The Sunday, August 30th, afternoon glass-off is a close second for a more manageable size. There are some big, clean days in between, but they come with challenging winds. Expect a long gap of poor conditions from the 26th to the 28th of August, and again at the very end. This is a spot for the dedicated, and when it fires, it’s worth the wait.
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.
