The Lowdown
G’day, Rusty here. We’ve got a solid run of surf coming up at Tubes (reef and point). The water’s sitting at 61°, which is a whopping 5° colder than usual for this time of year—so dig out the thickest wetsuit you’ve got, because that’s a proper chill.
The first decent chance rolls in on Sunday the 8th of September. Tuesday morning’s the pick of the early week: clean glassy conditions with a 4ft SSW swell, and the wave energy is moderate (697). It’s not big, but it’ll be fun for the intermediates. Tuesday afternoon drops off a bit. By Wednesday afternoon the 9th, things improve with a clean 4ft SSW swell and moderate offshore wind—nice lines forming.
Thursday the 10th is when it starts to get exciting. The afternoon session will have the experienced crew frothing: 6ft SSW groundswell with a 17-second period, moderate wave energy (2769), and clean conditions with a cross-offshore breeze. That’s a proper standout—long-period swell like that loves a reef setup like Tubes, so expect smooth, powerful waves.
Friday the 11th gets messy with onshore wind and rain, so give it a miss. Saturday the 12th is no good either—strong cross-onshore breeze and choppy.
Sunday the 13th afternoon turns it around: a clean 6ft SSW swell with light cross-offshore wind and 1229 energy. Another good one. Monday the 14th is a belter for experts—10ft SSW swell, clean, with offshore wind all day. That’s over 8ft, so only for the well-experienced. Tuesday the 15th is marginal, but Wednesday the 16th morning delivers 6ft SSW swell and moderate offshore wind—clean and punchy.
After that, a rough patch hits from Thursday the 17th through to the 18th, with onshore winds and messy 10ft SE swells—poor quality. Then Saturday the 19th morning cleans up with a 5ft SE swell and light cross-offshore breeze. Sunday the 20th is another standout: 7ft SSW swell, clean, with moderate offshore wind and strong energy (1813). The run continues into Monday the 21st afternoon with 6ft SSW swell and clean offshore conditions.
The true standouts are Thursday the 10th afternoon and Sunday the 20th—both offer clean, powerful SSW groundswell with good winds at Tubes. For the experts, Monday the 14th is a must.
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.
