The Lowdown
Alright, Rusty here again. Let’s break down what’s coming at Tubes.
The first real highlight is Tuesday afternoon, the 25th of August. Tubes is a sheltered reef and point, and it’s going to be handling a solid 10-foot SSW swell. The period is 15 seconds, so this is proper groundswell with plenty of punch. The wind is light and offshore from the SSW, so expect clean, lined-up walls. The water temp is a very unusual 57°F, a full 9°F colder than normal for this time of year, so you’ll want a thick suit. The wave energy is massive, with a reading of 4085, meaning there’s plenty of power. This is solid, quality surf for experienced surfers only—definitely not for beginners.
After that, conditions get messy. Wednesday the 26th is a write-off with strong cross-onshore winds. Thursday the 27th morning, however, is a glassy gem. The swell drops to 7 feet from the SSW, with a 12-second period. The wind is dead calm, so you’ll get clean, glassy faces. The energy is moderate (1553), and it’s a great call for anyone who can handle the size. Thursday afternoon gets a bit lumpy with a light cross-shore.
Friday the 28th and Saturday the 29th are small and marginal, with bumpy conditions. Saturday afternoon the 29th sees a cleaner window with a decent offshore wind from the SW and a 3-foot SSE swell, but it’s small. Sunday the 30th afternoon is where it picks up again: 5-foot SW swell with a 13-second period and a moderate offshore wind. The energy is solid (1224), and the surf should be clean and fun.
Monday the 31st looks good too. The morning is glassy with a 6-foot SW swell, and the afternoon is clean with a light cross-offshore breeze. Both sessions have consistent wave energy in the 850-900 range.
Now, here’s a stand-out in the second week. Tuesday the 1st of September sees a big jump in size. The afternoon session brings a 13-foot SW swell with a 14-second period. The wind is cross-offshore, and the energy is massive at 5035. This is serious, heavy surf for experts only. Wednesday the 2nd of September is even bigger, with a 16-foot SW swell in the morning, though the wind is a strong cross-offshore—still clean, but charging. Thursday the 3rd of September holds size, but the wind is cross-onshore, making it lumpy. Friday the 4th of September is a real standout: clean, moderate offshore wind from the SSW, with an 12-foot SE swell. The energy is high (2666), and the conditions are excellent for experienced surfers.
After that, it winds down. Saturday the 5th of September is poor with onshore winds. Sunday the 6th has a long-period 5-foot SSW swell (16 seconds) but bumpy conditions. Monday the 7th has a clean window in the afternoon with a light offshore and a 4-foot S swell. Tuesday the 8th morning is clean with a 4-foot WSW swell. The last few days from the 9th are small and choppy.
Best of the bunch: Tuesday afternoon the 25th of August for the big, clean groundswell, and Friday the 4th of September for the clean, powerful offshore conditions. Both are expert territory.
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.
