The Lowdown
Alright folks, Rusty here, looking at the lineup ahead for our region. Let's be straight – this 16-day stretch is a tough one to call a winner. The ocean's not playing nice much of the time. We've got a long, bleak run coming right out of the gate.
For the first few days, especially through Sunday and Monday (August 23rd & 24th), it’s pretty rough. We've got a strong cross-onshore wind and lumpy conditions making a mess of things. The water's sitting at 64.9°F, which is a big 3.8°F colder than usual for this time of year, so you'll definitely feel that bite.
Now, the first real glimmer of hope shows up on Tuesday morning the 25th of August. The wind goes glassy at Supertubos. It's a light swell though, only about 4.3ft from the west, with a short period. The overall wave energy is weak (159). It’s surfable, but it's pretty ordinary. Don't get your hopes up.
Wednesday the 26th and Thursday the 27th are a write-off with more choppy, cross-onshore junk.
Here’s the one that stands out in this whole outlook: Friday morning, August 28th at Supertubos. The swell is jumping up to 8.2ft from the WNW. That's a proper sized groundswell with a period of 11 seconds, giving us strong wave energy (1542). The wind is light from the NW, which is a cross-shore direction. This is going to create some proper, powerful barrels. This is definitely a session for the experienced crew – that size is well into expert territory. Bear in mind, the wind is light cross-shore, not glassy, but light enough to keep things clean.
After that Friday morning, the swell just vanishes. From Friday afternoon all the way through to the end of the first week of September, it's flat or near-flat. There will be a big gap of over a week with hardly a ripple at Supertubos. Most days the wave energy is below 100, with a tiny 0.3ft to 2.6ft of mostly weak, windswell leftovers. It's clean for the most part, but there's nothing to ride.
We see a pulse of deep, long-period energy (23-26 second period) arrive on September 6th and 7th, but the heights are tiny (0.7ft to 3.3ft). The wind is strong and offshore, creating a lot of surface chop for such a small, long-period swell. It’s not going to produce anything of quality.
So, in a nutshell: hold out for that Friday the 28th morning session if you're an expert. For everyone else, this is a lean period. It won't stay poor forever, but this stretch is rough.

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.
