The Lowdown
Alright, Rusty here, and I’ve got the lowdown on what’s shaping up over the next couple of weeks. It’s a bit of a slow burner to start, but there’s some proper juice further out if you can wait.
The main spot is Tubes, and it’s been a bit of a rough patch early on. The first few days are mostly messy, with building swells getting chopped up. The water at Tubes is running at a very unusual 59°F – that’s about 7°F colder than usual for this time of year, so you’ll want the thickest rubber you’ve got.
The first decent opportunity comes on Tuesday the 15th afternoon. We’ve got a 5ft SW swell with a 10-second period, and the wind goes light south cross-off. The combined energy is moderate (676), and it’ll be clean, fun little waves. A good warm-up.
Then we hit a quiet gap for a couple of days before the first standout. Wednesday the 16th morning is excellent, but for the experienced crew only. We’re looking at a solid 10ft SW swell, 12-second period, and a moderate offshore wind from the SW. The combined energy is strong (2960). That’s serious power, and it’s going to be clean. The afternoon holds a chunky 12ft SW groundswell (14-second period) with a cross-off wind – energy jumps to 5278 – but it’s marked as marginal, so tide will be the key.
The next real highlight, and the one to pin on your board, is Friday the 18th afternoon. You’ve got an 8ft SW swell with a solid 13-second period, a gentle cross-off wind, and the combined energy is strong (2138). It’s rated excellent for experienced surfers, and it’s clean. The sets will have proper shape and punch.
But if there’s one true standout across this whole window, it’s Saturday the 19th morning. It’s glassy, mate. Absolutely dead calm, a 8ft SW groundswell with a 14-second period, and the energy is strong (2659). For an intermediate or better, this is the session to aim for. The crowd profile at Tubes says "sometimes," so you might have company, but with those conditions, it’ll be worth paddling out.
After that, it drops off into a long stretch of blown-out junk from the 20th to the 24th, with strong cross-onshore winds and lumpy surf. A few days show winds of 25–30 mph, making it look more like a kiteboarding day than a surf.
There is a late flicker on Friday the 25th morning, with a moderate offshore wind and a smaller 5ft SSW swell (13-second period) with high energy for its size (1632), giving clean conditions. It’s a solid end to the run, but that Saturday the 19th glass is the one to chase.
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.
