The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell coming our way, but we’ve got to sit through a bit of a slow patch first. The main event is at Tubes, a reef and point break that’s been consistent and handles a south-southwest swell best. The water temp is a chilly 59°F, which is a massive 7°F colder than normal for this time of year – that’s seriously unusual, so you’ll want a thick wetsuit.
The week kicks off with a bang on Friday the 7th of August. Morning sees a 10ft south-west swell with a 13-second period, pushing a lot of energy. The wind is a light cross-on from the east, so it’s a bit bumpy, but the size is there. The afternoon gets wrecked by a fresh 15 mph cross-on, turning it choppy and messy, so Friday is a morning mission only.
Saturday the 8th looks better. The swell drops a touch to 8ft from the south-west, but the wind cleans up nicely. By the afternoon, we’ve got a solid 15 mph offshore breeze from the west-southwest, making for clean, groomed lines. The period is 13 seconds, so there’s real grunt there. This is one of the best windows early on.
Sunday the 9th holds size, with 10ft to 12ft south-west swell, but the wind is a strong cross-off and the conditions are junky. The energy is massive, but it’s a raw, windy mess. More of a looker than a surfer.
Monday the 10th is the real standout of the first week. Morning brings a 10ft south-southwest swell with a solid 12-second period and offshore winds from the south-southwest at 15 mph. The waves will be clean, powerful, and well-shaped. That’s the call for the experienced crew.
From Tuesday the 11th through to Saturday the 15th, we’re in a slump. The swell drops off, the wind turns onshore or cross-on from the east, and the quality tanks. There’s a tiny window on the morning of the 13th with a 5ft south-west swell and a very long 16-second period, but it’s onshore and lumpy. Not worth paddling out for.
Then we hit a sweet spot again on Sunday the 16th of August. Morning sees a 5ft south-west swell with offshore winds from the west-southwest at 12 mph. The waves will be clean and fun. The afternoon is even lighter, with a gentle cross-off breeze.
The absolute best of the whole forecast is Monday the 17th of August. This is a session to book off work for. The morning is magic: 7ft of south-west swell with a 14-second period, and glassy conditions – not a breath of wind. The energy is strong. This is a dream window.
Tuesday the 18th stays good with 6ft south-west swell and clean offshore winds, but nothing beats that Monday glass-off.
The last weekend of the forecast (Saturday the 22nd of August) looks like it could fire up again with a big 12ft south-west swell, but the wind is a strong cross-off. It’s promising, but it’s a long way out, so keep an eye on it.
So, to sum it up: the best of the best is Monday the 17th of August at Tubes. That glassy morning with the 7ft south-west swell is the one. The second pick is Saturday the 8th of August afternoon with offshore winds and solid 8ft swell. The rest of the time is a mix of waiting for the wind to play nice or dealing with the cold.
Stay frosty,
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.
