The Lowdown

Alright folks, Rusty here. Let’s talk about what’s coming up for Tubes. This is a sheltered reef and point set-up that loves a good SSW to SW swell, and boy, are we getting one. There’s a bit of a quiet start, but once it kicks off, we’re in for a proper run of waves.

The water is sitting at a very unusual 54°F, which is a massive 12°F colder than what’s normal for this time of year. You’ll be wanting a thick wetsuit, no doubt about it.

The first real action hits on Tuesday the 18th of August. Morning starts with a solid 8ft SW swell (13-second period) and a moderate offshore breeze – the lineup will be clean and the energy is already pumping (1804). By afternoon, it’s stepping up to 8ft SW with a gentle offshore wind, and the combined energy jumps to 2356. This is expert territory, but the conditions are excellent.

Wednesday the 19th is a standout. The morning is absolute magic: 10ft of SW groundswell, a 13-second period, and a slight offshore breeze. The energy is massive at 2536. It’s big, it’s powerful, and it’s clean. For experienced surfers only, this is the pick of the first week. The afternoon gets a bit of a fresh breeze, but still offshore.

Thursday the 20th is another day for the big dogs. Morning brings a pumping 13ft SW swell (13 seconds) with a light offshore breeze. The energy meter is reading a whopping 5309 – that’s serious power. The afternoon stays excellent with a 12ft SW swell and a light cross-offshore breeze.

The waves start to drop a bit over the weekend, but there’s still quality. Sunday the 23rd morning has a 13ft SW swell (13 seconds) and a gentle cross-offshore breeze, though the energy is slightly lower at 4861. The afternoon is cleaner with a 12ft SW swell and a light breeze.

Things settle down for a bit at the start of the next week, but then we get a proper long-range promise. Tuesday the 25th of August morning is a beauty: a 10ft SW swell with a very long 14-second period and a light offshore breeze. The energy is high at 2918. This is a groundswell that will wrap beautifully into the point.

The real standout, and I mean the one you circle on the calendar, is Tuesday the 1st of September. The morning is glassy, with a 8ft SW swell (13 seconds) and massive energy (2946). But the afternoon is next level: a 13ft SW swell with a 13-second period, light offshore breeze, and the combined energy hits an insane 10233. That’s a serious, serious swell. It’s only for experts, but if you’ve got the skill, this is the session of the forecast.

The crowds at Tubes can be a problem at times, so expect some company on the best days. The 30th of August also has a very interesting afternoon: a 6ft SSW swell with a 19-second period – that’s a very long period groundswell, and with a light offshore breeze, it’ll be a dream for the point.

There’s a stretch from the 26th into the 27th where the wind gets strong and messy, and the swell is on the small side, so you can take a breather then.

Stay safe, respect the reef, and don’t be a hero in the water if you’re not ready for the size.

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.
