The Lowdown
Alright, let’s break it down for Tubes – a reef and point break that’s sheltered and gets a good SSW swell. Water temp is 59°F, and that’s a solid 7°F colder than normal, so you’ll be reaching for the thickest wetsuit you’ve got. Crowds can be a thing here sometimes, but when it’s good, it’s worth it.
First chance to get wet is Saturday, August 29th, but don’t get your hopes up. Morning has a small 3ft S swell, 11-second period, and weak energy (482), but winds are cross-off so it’s clean. Still, it’s a pass. The afternoon is even smaller with 3ft SW swell and 13-second period, but offshore winds at 25 mph and weak energy (394) – it’s poor.
Sunday the 30th is a different story. Morning brings a solid 8ft SW swell, 10-second period, and strong energy (1366), with offshore winds at 20 mph keeping it clean. That’s very good. The afternoon holds 7ft SW swell, 10-second period, and lighter offshore winds at 15 mph, energy at 1181.
Monday the 31st of August is still good. Morning has 6ft SW swell, 12-second period, energy at 924, and light cross-off winds. The afternoon turns cross-shore, so it’s a bit less clean.
Tuesday, September 1st, is a winner. Morning: 7ft SW swell, 11-second period, very clean with light cross-off winds. Energy is strong at 1151. The afternoon gets stronger: 8ft SW swell, 13-second period, offshore winds at 25 mph, energy jumps to 1751. That’s a top session.
The clear standout of the first week is Wednesday morning, September 2nd. Swell hits 12ft from the SW, 13-second period, and the energy is massive at 3883. The wind is glassy from the ENE at just 5 mph. That’s excellent, but it’s big – only for the experts. The afternoon gets choppy and onshore, so get it early.
Thursday the 3rd has a good morning with 8ft SW swell, 13-second period, and offshore winds. Energy is high at 1937. But the afternoon is blown out by a near gale from the SSE.
From Friday the 4th through Tuesday the 8th, it’s a rough patch. The swell is still there, but the wind is mostly cross-on or strong, ruining it. Energy stays moderate to high, but the wind kills the quality. That’s a 3-4 day gap of not much.
Then we get small and weak on Wednesday the 9th and Thursday the 10th – energy drops to 384 and 162. Not worth it.
Now for the second week’s gem. Saturday, September 12th is a beauty. The morning is glassy with a 10ft SW swell, 14-second period, and massive energy of 3183. Excellent for the experienced crew. The afternoon holds 12ft WSW swell but with a shorter 10-second period, and offshore winds at 15 mph. Still very good.
Sunday, September 13th is also excellent. Morning: 10ft SW swell, 11-second period, strong offshore winds at 20 mph, energy at 3426. Afternoon: a touch bigger at 12ft, 12-second period, similar offshore winds, energy at 3123. Both days are for the serious surfers only.
So, circle Wednesday morning, September 2nd, and then Saturday and Sunday, September 12th and 13th. Those are the calls. Water’s cold, swell’s big, wind’s clean. Go get 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.
