The Lowdown

G'day, Rusty here, looking at the surf ahead for the Supertubos stretch. It's gonna be a bit of a mixed bag over the next couple of weeks, with a very slow start and then a couple of windows where it gets interesting.

We're starting off pretty grim, to be honest. The next few days are a write-off for any decent paddle surfing. Wednesday the 26th is a total no-go with onshore wind and a messy, weak 5ft swell. The water's a bit colder than normal for this time of year at 66°, which is a touch noticeable when you're sitting out there.

Things start to look up on Friday the 28th. It’s still not perfect, but we get a cleaner window. Friday morning is the real standout of the whole outlook: a clean 7ft swell from the WNW, with a solid 11-second period and a light NNW cross-offshore breeze. The combined energy hits a strong 952, so there's real power in the water. It's an advanced wave at that size, but for the crew who can handle it, that Friday morning session will be the one to circle on the calendar.

Friday afternoon holds with a similar 7ft NW swell, but the period drops slightly to 10 seconds and the energy is very strong at 1048, though it looks a bit more marginal for quality. Saturday the 29th is smaller and still clean, but nothing to write home about. Sunday the 30th afternoon has a fun little pulse: 5ft from the NW with a long 11-second period (moderate energy at 496), clean with a gentle offshore breeze – that's a good option for a relaxed session.

Then we hit a big gap. From Monday the 31st of August right through to the end of the first week of September, it goes completely flat or tiny. There are a few days with barely a ripple, like the 1st and 4th of September. That's a long stretch of no real surf.

Further out, around Saturday the 5th of September, there's a promising pulse showing. It's a fair way off, so don't book the time off just yet, but the numbers look good. Saturday morning could see a clean 5ft swell from the NW with a very long 13-second period and light N winds. The energy is moderate at 583. That long period groundswell will be best on this reef setup, giving you long, walled-up lines. If that forecast holds, it could be another quality session.

Sunday the 6th drops off a bit, and then it's back to small stuff again. There's a tiny glimmer on Thursday the 10th with a clean, glassy 3ft NW groundswell (182 energy), but it's pretty ordinary.

So the bottom line: the first few days are a total loss. The clear winner is Friday morning, 28th of August, at Supertubos – get on it. Keep an eye on that 5th of September window too; it could be a beauty.

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.
