The Lowdown
Alright folks, Rusty here. Let’s get straight into it for our local stretch at Supertubos. I’ll be honest, looking at the next 16 days, it’s a real mixed bag and we’ve got a long wait before anything worth getting excited about shows up.
The overall pattern is pretty flat and frustrated. We’ve got a run of several days with nothing but tiny, weak swell and a lot of cross-offshore winds keeping things marginal. The water temp is sitting at 68°, which is basically dead average for this time of year, so no surprises there.
The first real glimmer of hope doesn’t arrive until Saturday the 15th of August. Even then, it’s only a “surfable but very ordinary” morning. We’re looking at a clean 3 ft wave from the NW with a 9-second period, and the combined energy is a moderate 131. It’s not going to blow your mind, but it’s something to get wet on after a long dry spell.
The next real chance comes on Friday the 21st of August. The morning session shows a 2 ft NW swell with a short 10-second period. The combined energy is moderate at 129, and with a light offshore from the N, it’ll be clean. The afternoon jumps up to 3 ft from the NW with a period of 10 seconds, and the energy climbs to a strong 229. But the wind swings to a cross-shore, making it a bit messy.
The standout of the whole outlook, and the only one I’d really circle, is Saturday the 22nd of August. The morning is showing a 4 ft NW swell with a 9-second period and a strong energy reading of 219. The wind is a light cross-onshore, which isn’t perfect, but it’s the biggest swell of the period. At 4 ft, it’s still fine for intermediate surfers, not too big. This is your best bet if you want a wave with a bit of push.
Overall, it’s a lean period with a lot of waiting. The 21st and 22nd are the only real standouts, and even then, they’re not world-class. Keep an eye on the forecasts, but for now, we’re just hoping for a change.
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.
