The Lowdown
Alright, let’s break it down in feet and degrees Fahrenheit. Rusty here.
This forecast is all about one spot – Tubes. It’s a reef and point that breaks consistently, but being sheltered, it needs the right south-southwest swell to fire. Water temp is sitting at 52°F – that’s about 14°F colder than normal for mid-August. Seriously unusual, bring a thick suit.
The first weekend is nothing special. Friday 14 August is a bust: cross-onshore wind with a weak 4-5ft SW swell, energy at 930. Saturday morning (15 August) turns glassy with tiny 3-4ft surf, energy just 657. Sunday 16 August improves a bit – cleaner, with 5ft SW swell, moderate energy around 689.
Things kick off on Monday 17 August. That morning we’ve got 8ft of SW swell from a 14-second groundswell, energy a strong 2094, and a gentle offshore wind. That’s clean, powerful, and only for experienced surfers. The afternoon stays clean with a side-offshore breeze.
Tuesday 18 August morning is glassy with 6-7ft SW swell, energy still strong at 1408 – a fantastic session for the early bird. Afternoon turns choppy with a 25 km/h cross-on wind.
From Wednesday 19 August through Thursday, we get a clean, consistent run: 8ft SW swell with gentle offshore winds on Wednesday (energy around 1969), and 6ft on Thursday afternoon after a morning onshore breeze. The energy stays solid.
Now the standout: Saturday 22 August afternoon. This is a monster – 20ft SW swell, 16-second period, energy a massive 16386, and a 25 km/h offshore breeze. This is expert-only, world-class, once-in-a-season type surf at this point. Be prepared for a crowd, as Tubes can see people on days like this.
Sunday 23 August holds size at 13-15ft, but the wind is onshore and messy. Next good expert window is Tuesday 25 August morning: 8ft SW swell, offshore wind, energy 2362 – excellent.
The second week stays active with clean 10ft+ swells on Wednesday 27 August morning (offshore wind), but the energy drops gradually. By Friday 28 August the wind is howling, and the last days of the month are choppy and poor.
Your best bets: Monday 17 August, Tuesday 18 August morning, Wednesday 19 August, and the epic Saturday 22 August afternoon for the big dogs. Get after it.

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.
