The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Supertubos.
Alright, I gotta be straight with you – this 16-day run is looking pretty grim for a paddle. We’ve got a massive gap of tiny, unsurfable waves stretching from now all the way through to Friday the 28th of August. For over two weeks, it’s flat or ankle-biters. The only saving grace is that Supertubos is a fairly consistent break, so this kind of blank spell isn’t the norm, and forecasts can change.
The one and only glimmer of hope shows up on Friday afternoon the 28th of August. We finally see some new energy roll in. The swell pops to 3ft from the NW, with a period of 7 seconds. That’s a short-period windswell, and the combined energy is moderate at 107. The wind is blowing cross-off from the NNW, which is the right side for Supertubos, so it should be clean. This is the standout, but it’s not a classic. It’s a fin-short, choppy little pulse, and with that short period, it’s not gonna have the famous Supertubos barrel. It’s better than nothing, but it’s a session for a grovel board. Keep your expectations in check.
A quick note on the water: since we’re looking at Supertubos first, the water temperature data doesn’t show any anomaly, so the temp is about average for this time of year.
That’s the long story short, folks. A long wait for a short, clean window. Keep an eye on it, but don’t hold your breath.
Rusty.

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.
