The Lowdown
Alright mate, Rusty here. Let’s break down what’s on the cards for our local zone. It’s a long haul this time, with a lot of flat days, but there’s a proper reward at the end if you’re willing to wait.
First thing you need to know: the water at Supertubos is sitting at 65°, which is about 4° colder than what we’d normally see this time of year. That’s a proper cold snap, so you’ll want a thick steamer.
The first ten days or so are rubbish. Starting Monday the 24th of August, we’ve got a strong southwesterly wind blowing at 25 mph, with a stormy 10ft swell from the west-southwest, but it’s a short 8-second period and the combined energy is strong at 1106. It’s just messy, onshore junk. Tuesday through Thursday stays poor, with onshore and cross-onshore winds and lumpy, weak swell. Thursday the 27th shows a 7ft west swell but it’s cross-onshore and choppy, so no good. Honestly, it’s a write-off until the end of the week.
Friday the 28th of August is the first real flicker. You’ve got a 8ft WNW groundswell with an 11-second period and clean cross-off wind from the north at 12 mph. The combined energy is strong at 1757. It’s only a marginal call because of tricky tides, but it’s the best looking day in that first block. After that, it goes dead flat. From the 29th of August right through to the 4th of September, we’ve got tiny waves, mostly under 3ft, and even with clean north winds, there’s just no power. It’s a proper drought.
Then on Saturday the 5th of September, a NW groundswell builds to 7ft to 7ft with a 12 to 13-second period. Winds are clean from the north-northwest, and the combined energy sits at 1337. That’s a solid, clean session if the tide plays ball, but it’s still rated as marginal.
Now, the real standout is Monday the 7th of September. Early morning it’s glassy – wind is light west at 3 mph – and a massive 12ft swell from the northwest with a very long 17-second period rolls in. The combined energy is a thumping 5866. That’s serious, powerful groundswell. For a spot like Supertubos (a beach and reef setup), that long period with clean conditions and offshore wind is prime. But that size is for experienced surfers only. The afternoon goes onshore and messy, so that morning window is your golden ticket.
To sum it up: a long flat spell from late August into early September, with a clean but marginal day on the 28th of August, a decent shot on the 5th of September, and a proper barrel waiting on the morning of the 7th of September if you’ve got the patience.
Keep the wax warm. This is Rusty, out.

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.
