The Lowdown
Alright, this is Rusty. Let's talk about what's on the menu for the next couple of weeks.
Honestly, the first week is a total write-off. We've got a flat spell that runs from the start all the way through to the morning of the 7th of September. There's just nothing doing. The wind is a stubborn cross-offshore from the north, but with swell heights barely scraping 3 ft and the energy in the water sitting at a weak 103 (moderate), it's not worth paddling out for. The 31st of August and 1st of September are particularly grim.
Things start to stir on the morning of Monday the 7th of September. The swell picks up to 2 ft from the NW, with a period of 14 seconds – that's a proper groundswell. The energy jumps to 214 (moderate), but it's still just surfable, not special. The real turning point is the afternoon of the 14th of September. The combined energy surges to 1251 (very strong), and the swell is a solid 5 ft from the NW with a very long 17-second period. The wind is a clean cross-offshore from the NNE. That has the makings of a serious session.
But the standout, the absolute best on offer, is the morning of Tuesday the 15th of September. That's the one to circle. Supertubos is awake. The swell is a solid 7 ft from the NW, with a 13-second period, and the energy reading is a massive 1380 (very strong). The wind is light offshore from the ENE – practically glass. This is serious, expert-level power. The NW direction is exactly what this break wants. It's a fairly consistent spot, but crowds are possible, so get in early. The water temp is about average for the time of year at 68°.
The rest of the second week has some other smaller pulses, but nothing touches that Tuesday morning. The 14th afternoon is a good warm-up, but the 15th morning is the clear winner.

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.
