The Lowdown
Alright folks, Rusty here. Let's get straight into it. We've got a solid run of surf coming up at Tubes, a sheltered reef and point setup that loves a solid SSW groundswell. The water's sitting at a chilly 59°, which is a massive 7° colder than normal for this time of year – that's seriously unusual, so you're gonna need a thick steamer and maybe some booties if you're heading out.
The action kicks off on Thursday, August 6th. The morning is the pick of the whole early period. We're looking at a clean 12ft set from the SW with a 13-second period, and a light offshore breeze from the southwest. The energy is pumping hard with a combined reading of 4581. This is proper, powerful groundswell. Keep in mind, at this size, this is strictly for experienced surfers only. The afternoon sees the wind pick up to 15 mph, still offshore, but it'll get a bit lumpy, so the morning is the window.
Friday the 7th, the swell holds at 10ft, but the wind swings around to the ENE, making it onshore and messy. Saturday the 8th, the swell drops to 8ft, and while the wind is offshore from the WSW, it's blowing a fresh 19 mph in the morning. It's clean, but that wind is strong. Sunday the 9th is a write-off with heavy rain and strong cross-offshore winds, although the swell bumps back up to 12ft to 13ft. It's just too messy.
The real standout for the whole outlook is Monday morning, August 10th. The swell drops to a much more manageable 8ft from the SW, period is still a nice 12 seconds, and the wind is a light 6 mph from the SSE, keeping it clean. The energy is still strong at 2092. This is excellent surf for experienced surfers without the crazy size of the previous days. Tuesday the 11th has some potential with an 8ft SSW swell and next to no wind in the morning, but it's a cross-on wind, so it won't be as clean.
We hit a bit of a lull mid-week. Wednesday the 12th and Thursday the 13th are poor, with onshore winds and dropping swell. Friday the 14th is small and weak. The next real glimmer comes on Saturday afternoon, August 15th. The swell picks back up to 5ft from the SW with a 16-second period, and the wind goes light offshore from the SSW. The energy is moderate at 1596, and it's clean. This is a nice, mellow option for the weekend.
Looking further out, we have another promising window. Tuesday morning, August 18th, looks solid: 6ft SW swell, 12-second period, and a moderate 12 mph offshore breeze from the WSW. Energy is moderate at 1026. The morning of Wednesday, August 19th is glassy – zero wind, clean, with a 7ft swell. It's a bit short period at 10 seconds, but it's a beautiful, clean morning on the water. Then, on Friday morning, August 21st, we get a glassy start with a 6ft SSW swell and a 13-second period, very clean. The afternoon of the 21st, however, the swell jumps to a massive 13ft from the SSW with a very long 17-second period, and the energy goes through the roof at 8061. That afternoon is for experts only, and the wind is light cross-on, so it won't be perfect, but the power will be insane.
So, to wrap it up: the best bets are Thursday morning, August 6th, for the biggest, cleanest power, and Monday morning, August 10th, for a slightly smaller but still excellent session. The glassy mornings on the 19th and 21st are also worth setting the alarm for.
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.
