The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for us over the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start. The first real action isn't until Saturday morning, the 29th of August, at Supertubos. That morning, the swell is coming in from the NW at 5 ft with a period of 9 seconds, and the combined energy is a moderate 427. The wind is a light cross-off from the N at 9 mph, keeping things pretty clean. The water temp is sitting at 67°, which is about normal for this time of year. It’s a decent wave, but honestly, it’s the only real highlight in the first few days.
After that Saturday morning, things drop off quickly. The afternoon gets smaller, and from Sunday the 30th right through to the morning of Friday the 11th of September, we’re looking at a long stretch of poor to marginal conditions. The swell drops way down, the wind picks up strong from the N, and there’s just not much to get excited about. It’s a real gap of about 12 days with no worthwhile surf.
Now, the one standout in this whole outlook is the morning of Friday, the 11th of September. Supertubos is back on. We’ve got a solid NW swell at 5 ft again, with a 9-second period, pushing the combined energy to a strong 367. The wind is light from the N at 9 mph, and with the skies partly cloudy, it’s looking clean. This is easily the best window we’ve got. It’s not huge, but it’s well-shaped, and that offshore wind will keep it tidy. For a spot that’s fairly consistent and a bit exposed to the SW swell direction, this is the one to circle on the calendar.
After that, the weekend of the 12th and 13th September looks a bit messy again with the wind picking up, so that Friday morning is really your only shot at something special.
So, to sum it up: the first real surf is Saturday morning the 29th, but it’s a one-off. Then a long, dry spell until Friday the 11th of September. That’s your best bet. It’s a bit of a wait, but forecasts can shift. Keep an eye on it.
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.
