The Lowdown
Alright, Rusty here. Let's have a look at what's coming up at Tubes.
The forecast is opening with a quiet start, but don't let that fool you. We've got a solid run of swell lined up, but you've got to pick your moments. The real standout is a mid-week pulse that's going to be firing. The water is sitting at 59.2°, which is a whopping 6.8° colder than usual for this time of year, so you're definitely going to want a decent hood and gloves.
The first real action kicks off on Tuesday afternoon, the 4th of August. We're looking at a 4.3ft SW swell with a 11-second period, and the wind is going offshore, cleaning things right up. The combined energy is moderate at 773, and it's a solid start to the week.
Wednesday the 5th of August is the pick of the early run. The afternoon session is the one. There's a 5.6ft SW groundswell with a long 16-second period, and the wind is offshore again. The combined energy jumps to a strong 1551. This is a sweet spot for intermediate surfers. The long period will make for some well-shaped, powerful lines off the point, so you'll get some proper barrels.
Thursday the 6th of August is for the crew who've earned their stripes. The morning swell is 11.5ft from the SW, and with a light cross-offshore breeze, it's clean. The combined energy is a massive 4581. This is solid, powerful stuff. It's strictly for experienced surfers only. The afternoon holds similar size and power with offshore winds.
Friday the 7th of August morning is a gift. The swell drops to a still-chunky 8.2ft from the SW, but the wind is glassy. Absolutely dead calm. For a reef and point break like Tubes, that's as good as it gets. The waves will be clean, flawless, and lined up. The energy is still strong at 2248. This is a top-tier session for the good crew.
The weekend and into the following week gets a bit messy. Saturday the 8th of August is still big, with a 9.8ft SW swell and offshore winds in the morning, but the wind builds in the afternoon. Sunday the 9th of August brings rain and strong winds, with the swell hitting 14.8ft with a shorter period. The energy is over 5000, but the conditions are marginal. This setup is looking more interesting for a kite session than a paddle session.
The swell stays big through to the middle of the second week, but the wind direction is all over the place, mostly onshore or cross-onshore, making it lumpy. The 14th of August (Friday afternoon) has a glimmer of hope with a 7.2ft ESE swell going glassy, but it's not the main direction for the spot.
The second week wraps up with a return to form. Monday the 17th of August is another standout. The morning sees a 11.5ft SW swell with a 13-second period and a light offshore breeze. The combined energy is a strong 3507. It's clean, powerful, and for the experienced crew. The afternoon remains solid with a moderate offshore wind. Tuesday the 18th of August also holds some good clean waves with a 7.5ft SW swell and fresh offshore winds.
So, to sum it up: the best bets are the afternoon of Wednesday the 5th of August for a solid, fun session, and the morning of Friday the 7th of August for the best conditions you'll see all week. The big stuff from Thursday the 6th and Monday the 17th is for the experts only.

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.
