The Lowdown
Imperial
Alright, Rusty here. Let's break down what's on the menu at Tubes. It's a bit of a rollercoaster, so pay attention.
We start off solid on Monday the 14th. Water temp is normal for this time of year, no drama. Morning session has a glassy surface thanks to a light West wind, and a clean 4ft SSW groundswell with a long 13-second period. The energy is moderate (543). It's not gonna scare anyone, but it'll be clean. Afternoon holds up with clean conditions and a 4ft swell.
Tuesday the 15th is smaller but still clean. You're looking at around 3ft in the morning, with the same long-period SW swell. The energy is weaker (237), but it's ridable. Afternoon picks up to about 4ft.
Wednesday the 16th gets real. A big 10ft SW groundswell hits in the morning, period pushing 14 seconds, and the energy is huge (6397). This is for experts only. The wind is a 15 mph cross-off from the WSW, so it's clean, but it's a lot of water moving around.
From Thursday the 17th through Saturday the 19th, forget it. Strong onshore winds from the ESE at 15-22 mph turn the ocean into a lumpy mess. Swell is there, around 6ft to 6ft, but it's just poor.
Now, Sunday the 20th is your big standout. The wind goes glassy out of the WSW in the morning, and we get a solid 10ft ESE swell. The energy is pumping (2522). This is excellent, powerful surf, but with that size and a 10-second period, it's strictly for the experienced crew. The afternoon is even cleaner with a light offshore breeze from the SW. Mark this one down.
Monday the 21st is a treat, too. A very good 6ft SW swell with clean conditions and a light offshore. Energy is strong (1236). Tuesday the 22nd is still good, with a 5ft SW swell and clean conditions in the morning.
Looking into the second week, we've got another big window. Sunday the 27th, a solid 12ft SW swell with clean conditions. But Monday the 28th is the real gem on the long-range forecast. It's showing a massive 13ft SSW groundswell, 15-second period, with a light offshore breeze. The energy is enormous (6060). That's a proper big-wave day for the experts at a break that knows how to handle it. It's a long way out, but the potential is there for some absolute bombs.
Pick your battles. Sunday the 20th and Monday the 28th are the ones that'll get your heart racing.
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.
