The Lowdown
Alright, let’s talk about Supertubos. We got a long 16-day window here, and I gotta be straight with you – for a spot that can be world-class, this stretch looks tough. There’s a big dry patch at the start with almost no surf to speak of.
The first few days, from Monday the 17th right through the rest of that week and into the next, the swell is tiny. We’re talking about 0.3ft to 2ft of weak, short-period energy. The combined swell energy sits in the weak range, between 15 and 89. It’s just flat and not worth a paddle. You’ll get clean mornings with that light NE wind early on Monday the 17th, but there’s nothing to ride. That hard run of poor conditions lasts right up until around Thursday the 27th.
Now, Thursday the 27th afternoon shows a flicker of life – a 3ft NW swell with an 8-second period, pushing the combined energy into moderate territory (114). Still, the forecast score says it’s poor. The winds are strong cross-off from the NNW at 15 mph, which cleans it up, but the swell’s too weak and short-period to get excited about.
The only real standout, and it’s a long-range one so take it with a pinch of salt, is Friday the 28th afternoon. The forecast shows a 7ft NW swell with an 11-second period, pumping the energy right up to 972 – that’s strong. This is expert territory; it’s too big for beginners. The direction from the NW is a good match for Supertubos’ optimum SW direction, though with a bit of west in it. The wind is cross-off from the north at 15 mph, which should keep it reasonably clean. This setup screams hollow, fast barrels for the crew that can handle it. Keep an eye on that one, but remember it’s a week and a half away – a lot can change. For now, the rest of the outlook is a waiting game.

Information about the Supertubos Surf forecast
The above surf forecast table for Supertubos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Supertubos can be found by selecting the local surf guide option on the grey menu. Our Supertubos 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 (Supertubos) 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 Supertubos 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.
