The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Supertubos and, to be honest, it’s a grim stretch ahead. There’s no standout session in this 16-day window, and I wouldn’t even bother paddling out for most of it. The whole run is a write-off for decent waves.
The pattern is poor from the start. Sunday the 30th of August kicks off with a 4ft north-west swell at 8 seconds, but the wind is a cross-off at 12 mph, so it’s messy. The wave energy is moderate (254), but the conditions are just poor. Through the week, we get a few pulses of swell, but the wind stays stubbornly cross-off or worse, with speeds up to 19 mph, and the surf quality is repeatedly described as “poor surf conditions” or “marginal.” Monday the 31st has a 5ft NW swell, but the wind is up to 19 mph, and it’s a no-go. By Tuesday the 1st of September, the swell drops to 0.3ft with a very long 15-second period, but it’s useless.
The only faint glimmer is on Wednesday the 2nd of September morning, when we get a 5ft NW swell at 7 seconds, with a light 9 mph cross-off breeze. The combined energy is moderate (377), but it’s still only rated as “marginal.” The wind is clean, but the short period (7 seconds) means the waves will be weak and crumbly, not the tubing Supertubos is known for. It’s not worth a paddle.
After that, it’s a long, bleak stretch. From Thursday the 3rd of September right through to Monday the 14th of September, the swell is tiny – mostly under 3ft, often below 2ft – with only a brief lift on Tuesday the 8th of September morning (3ft, WNW, 11 seconds, 242 energy) but with a cross-off breeze that still leaves it “surfable but very ordinary.” The wind gets onshore a few times, especially from the 12th of September, with a 16 mph SSW wind and choppy conditions. Water temperature on the first day is 68°F, which is about average for the time of year, not that you’ll be bothered.
There’s a massive gap of no worthwhile surf from the 3rd of September right through to the end of the forecast. The best you can say is that the area is fairly consistent when swells hit, so this blank run is a bit of a cruel spell. But for now, leave the board in the garage. Forecasts can change, but this one is stubbornly poor.
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.
