The Lowdown
Right off the bat, the lineup’s looking pretty bleak. We’ve got a stretch of poor surf ahead, starting this Saturday morning (5 September) with a weak 3ft at 9 seconds from the WNW at Supertubos. The energy reading is weak at 101, and while the water’s clean, it’s just ordinary at best. The north-northwest breeze is blowing cross-off, but it’s not enough to save this one. Honestly, the next several days are a write-off. Saturday afternoon drops to a zero, and Sunday sees even less size at 3ft with the energy dipping to 95. It’s flat and frustrating, and the water temp is running 1° colder than average, so it’s a bit nippy for this time of year.
We’re looking at a long, dry spell here. From Monday (7 September) through Wednesday (9 September), the surf stays poor, with a small pulse on Monday morning 5ft at 12 seconds, but the cross-off wind has it messy and the energy jumps to 691, yet it’s just not worth paddling out for. Tuesday and Wednesday are all close-outs and wind. The gap here is substantial—this poor run stretches from the 5th all the way through the 14th. You’re better off finding something else to do for a week and a half.
Then, on Tuesday morning, 15 September, things start to stir. The ENE offshore wind kicks in, light at 6 mph, and the swell is 2ft at 15 seconds from the NW. It’s still small, with energy at 178, but that long period groundswell is a hint of better things. The morning is clean, and Supertubos is a beach and reef setup, so that long period might be a bit straight, but it’s a start. That afternoon, the swell bumps to 3ft at 14 seconds, but the wind shifts cross, and it gets a bit bumpy.
The real standout is Wednesday morning, 16 September. We’ve got 5ft at 11 seconds from the NW, with energy at 617. The wind is nearly dead, a slight air from the NNW at 3 mph, leaving it glassy and clean. This is the pick of the whole window. It’s a proper groundswell, decent size, and the conditions are as good as it gets. You’ll want to be out there early. The afternoon holds at 5ft, but the wind picks up a touch and it gets more marginal.
After that, it fades again. Thursday and Friday (17-18 September) see the swell drop back to the 3-4ft range with moderate northerly cross-off winds—surfable but unremarkable. Energy drops back to the 100-200 range. The following weekend (19-20 September) looks small and ordinary, with a light ESE wind on Saturday morning keeping things clean but the swell only at 3ft at 9 seconds. Sunday gets a bit choppier with a WSW cross-on wind.
So, if you can hold out, Wednesday morning the 16th is the one. It’s got the size, the period, and the light wind. Everything else is just waiting for the next pulse. Keep an eye on it, but don’t hold your breath for the rest.

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.
