The Lowdown
Alright, Rusty here. Let's chew the fat on what Tubes is looking like.
The next couple of weeks have a few solid pulses, but you'll need to pick your moments. We've got a slow start before some serious groundswell moves in and makes a real statement.
First chance for a paddle is Tuesday, September 15th in the afternoon. Tubes will have a clean 4ft SW swell (weak energy rating for the size, a bit odd), with a light cross-offshore breeze. It's surfable but nothing crazy, and the water is a very unusual 61°, a full 5° colder than usual for this time of year. You'll want a thick suit.
Then on Wednesday morning, September 16th, a fresh 22 mph offshore from the SSW hits a solid 10ft SW swell with a 14-second period. The wave energy is pumping - a strong reading. That's a proper groundswell, and with that offshore wind, it'll be clean as a whistle. This is for experienced surfers only at that size.
The weekend after that goes messy with strong cross-onshore winds. Patience.
The first real standout is Sunday, September 20th. Glassy conditions in the morning with a 7ft SW groundswell (14 seconds) and strong energy. Following that, the afternoon goes light offshore with a 8ft SW swell. That is the pick of the first week for clean, powerful waves.
Now for the big show. The second week is all about Sunday, September 27th. We're looking at a massive 12ft SW swell (14-second period) hitting with 4691 wave energy, under a gentle 10 mph offshore wind. That's a huge, consistent, and perfectly groomed groundswell. Tubes on that reef and point will be absolutely world-class. It's an expert-only day.
Before that, Wednesday, September 23rd offers a solid 12ft WSW swell (10-second period) with a 10 mph offshore. It's a bit shorter period, but clean and powerful for the big-wave crew.
After that peak, the swell drops back under 3ft towards the end of the month, with the wind getting on it again.
So for the best waves on offer, mark your calendar for Sunday the 20th for a clean, big session, and Sunday the 27th for the absolute monster of the window with perfect offshore conditions. Both are for experts only due to size. Tubes can get busy sometimes, but with these size swells, you might get a more select crew out there.
Stay wet.
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.
