The Lowdown
Alright, let me have a look at what’s on the table.
Right off the bat, I gotta be straight with ya – the next week or so is looking pretty flat and sad for Supertubos. We’ve got a proper dry spell on our hands. From Wednesday the 19th right through until early on the 26th, there’s basically nothing worth paddling out for. Tiny little scraps of swell, mostly under 2 feet, with weak energy (under 100) and poor conditions. A few mornings might look clean, but the waves just aren’t there. It’s a real bummer.
Then, things start to wake up around Wednesday the 26th. The swell finally shows up from the NW, pushing 6 feet on the Wednesday morning with moderate energy (474). The wind’s blowing straight onshore from the SW though, so it’ll be messy. By Wednesday afternoon, the wind swings around to a cross-off from the NNW at 19 mph, and the waves drop a little to 5 feet, but the energy is still solid (314). That afternoon window could be the first real chance to get wet, but it’s still a bit rough around the edges.
Thursday the 27th morning looks better. We’ve got 5 feet NW swell with a period of 8 seconds – short period, so it’ll be a bit fat and dumpy at a beach and reef setup like this – but the wind is a clean cross-off from the N at 16 mph. The energy is solid (345). It’s not perfect, but it’s the best we’ve seen so far. After that, it fades again into nothing for the 28th.
Saturday the 29th brings another pulse: 5 feet NW swell in the morning, but with cross-shore winds that’ll chop things up. The afternoon cleans up a bit with cross-off wind, 5 feet, and energy at 311. It’s still only marginal – not a standout, but at least there’s something to surf.
Now, the one that’s got my attention is Monday the 31st of August. That’s a week and a half out, so take it with a pinch of salt, but the models are hinting at a proper pulse. We’re looking at 7 to 8 feet NW swell with a long period of 13 seconds – that’s groundswell, proper energy (1565 to 1823). That’s strong, meaty stuff. But the wind is howling from the N at 19 to 22 mph, cross-off, so it’ll be blown but not completely trashed. At this size, Supertubos gets heavy – that’s expert territory only. The long period will make the waves jack up fast, and with that much energy, the inside will be a washing machine. If you’re a charger, that’s your window. For the rest of us, it might be a watch-and-wonder day.
After that, it drops right back to tiny, weak leftovers from Tuesday the 1st onward.
So, if I’m picking one true standout, it’s Monday the 31st – big, powerful NW groundswell, cross-off wind, and all that energy. Just know it’s for the experienced crew. The second-best shot is probably Thursday the 27th morning – smaller, cleaner, more manageable, but not nearly as exciting.
Overall, there’s a big gap of flatness up front, then a few days of marginal to decent surf, and one potential cracker at the end if the forecasts hold.

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.
