The Lowdown
Alright folks, Rusty here. Let’s break down what’s happening at Tubes.
The first few days are a total bust. The wind is all over the place, cross-onshore and lumpy, making the surf a mess. The water is sitting at 64°, which is a touch colder than average for this time of year, so your wettie needs to be a good one.
Things start to turn around on Tuesday, August 4th. The wind swings offshore from the WSW, cleaning the waves up nicely. We’ve got a 5ft swell from the SW with moderate energy. It’s not huge, but it’s clean and rideable.
The big one to circle is Wednesday afternoon, August 5th. The wind is clean offshore from the SSW, and the swell jumps to 8ft from the SW with a 14-second period. The energy is pumping, and it’s going to be excellent for experienced surfers. This is the best session of the window.
Thursday, August 6th is massive. The morning has a huge 18ft SW swell, but the wind is fresh and cross-offshore, keeping it clean. The energy is enormous. This is for experts only. The afternoon lightens up a bit with a 15ft swell and lighter winds, scoring the highest rating we see. Friday, August 7th afternoon is also excellent with a clean 10ft swell and offshore winds.
Saturday morning, August 8th is a dream. The wind is glassy, dead calm, with a solid 10ft SW swell and a 14-second period. The energy is very strong. The window is short though, as the afternoon turns choppy.
The second week has some interesting moments. Monday, August 10th morning has a fresh offshore wind, but the swell drops to 5ft. Wednesday, August 12th has a massive 12ft to 13ft SW swell, but the onshore winds and unknown conditions make it a gamble. Thursday, August 13th has a 10ft swell with a fresh cross-offshore wind, so it should be clean but windy.
The final standout is Saturday morning, August 15th. Light winds and a clean 10ft SW swell with strong energy. A solid way to finish.
So, to sum it up: the first week is a wash until Tuesday, August 4th. The best bets are Wednesday afternoon, August 5th and Saturday morning, August 8th. The second week has some big swells, but the winds are less reliable. Keep your eyes on that Wednesday the 5th.
Rusty out.

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.
