The Lowdown
Alright, Rusty here, on the situation at Tubes.
Got some good windows ahead, but you gotta be smart. The water temp is about 6°F colder than usual for the time of year, which is a big deal. It's gonna feel like a different season, so suit up.
First real standout: Tuesday, August 25th. All day looks sweet. Morning brings a solid 8ft swell out of the SW, period of 13 seconds, packing a lot of energy (3456). Wind is a moderate offshore from the WSW, keeping it clean. The afternoon gets even better – light 6 mph offshore breeze, same 8ft swell, but the period stretches to 14 seconds for some real lined-up sets. This is the best call for experienced surfers in the first week. It's a reef and point break, so those longer period groundswells will wrap in nice. Just know crowds can pop up here.
Wednesday the 26th is a hard pass. Swell jumps to 10ft but a strong onshore wind from the E makes it choppy and lumpy. Leave it.
Thursday the 27th is something else. The morning is glassy with zero wind, a 7ft SSW swell, and a 12-second period. That's as clean as it gets. Energy is still strong (1433). Afternoon drops to 5ft but stays clean with a light cross-off breeze. Still fun.
From Friday the 28th through to Monday, September 1st, it’s a consistent run of small to moderate, clean surf. Swell hangs around 3ft to 5ft from the S and SW with plenty of offshore and glassy wind windows. Good for a mix of abilities, nothing crazy.
Then the big one again. Wednesday, September 2nd, the swell hits 12ft out of the SW with a 14-second period. The morning is clean with light offshore wind. This is serious – long-period groundswell (energy of 4983). This is for experts only; that size at a reef will be heavy. The afternoon wind goes mad at 31 mph offshore, making it a battle to paddle in.
Thursday, September 3rd, keeps the 12ft size going, glassy in the morning, dropped period to 11 seconds, but still heavy (3046). Afternoon stays clean.
After that, it gets messy. Friday the 4th has a big 12ft SSW swell but onshore and cross-onshore winds ruin it. Saturday the 5th sees the swell drop with some clean glass but weakens. The week starting September 6th looks mostly poor with cross-onshore winds and rough conditions, though maybe a clean window on the 8th.
Bottom line: Tuesday, August 25th is the solid pick for consistency and good wind. But the true gem is Thursday morning, August 27th – 7ft, glassy, perfect. Circle that one.
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.
