The Lowdown
Alright folks, Rusty here. Let’s have a look at what Supertubos has on offer over the next couple of weeks.
Honestly, for the most part, it’s looking like a tough stretch. There’s a long dry spell right out of the gate with no real surf to get excited about until the middle of the second week. The waves in the water are minimal, and the wind is often making a mess of things or just not cooperating. It’s one of those periods where you might want to keep your board in the car just in case, but don’t hold your breath.
The first real hint of something half decent comes on Monday the 14th of September. Nothing to write home about, but the morning is glassy with a tiny 2ft WNW swell. It’s clean but tiny. The afternoon shows a bit more life with a 3ft NW swell, period around 11 seconds, and the combined energy is moderate at 217. The wind is a cross-offshore from the NW, keeping things clean enough, but the surf is just "surfable waves but very ordinary conditions." So, it’s a session for the longboard or a fun little grovel, not a day to be charging.
Things go quiet again for most of the rest of the week. A lot of days with wind howling from the north at 18-25 mph, or just flat spells. There’s a brief blip on Thursday the 17th with a 3ft NW swell and moderate energy (241) in the afternoon, but the northerly wind is up at 22 mph, making it a messy, blown-out affair. Not worth paddling out.
Now, the one that actually catches my eye is Saturday the 26th of September. The morning session here at Supertubos is the best bet in this entire 16-day window. The swell is a clean 3ft from the NW, period around 10 seconds, giving moderate wave energy of 162. The wind is light and cross-offshore from the north, keeping the faces clean. The surf report says "surfable waves but very ordinary conditions," but that’s the best we’re going to get. That’s the standout morning. The afternoon is the same size swell, but the wind jumps to 18 mph from the north and it gets messy. So, if you’re keen, get in the water early on Saturday the 26th.
Water temps are about average for this time of year, so no need to worry about a thick wetsuit.
That’s the long and short of it. A long waiting game for one window of decent, clean fun. Keep an eye on it, because forecasts can shift, but right now, that Saturday the 26th is your best shot.
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.
