The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Supertubos.
To be honest, the next week and a half is a bit of a tough watch. The forecast is dominated by small, weak swell and persistent cross-offshore winds. While the wind is technically offshore, it’s blowing hard enough to keep things from really cleaning up, and the wave heights are tiny. There’s a real gap in quality surf here. From Thursday the 6th right through until Sunday the 10th, the swell is barely 1ft to 3ft with weak energy. The combined energy readings are all under 100 (mainly 29 to 89), which is a clear sign of a flat spell. The water temp is sitting at 67°, which is about 1° cooler than average for this time, so nothing too unusual, just a touch fresh.
We start to see a slight pulse of energy on Monday the 10th morning, with a combined energy of 126 (moderate) and a 3ft swell from the NW, but the period is only 8 seconds. That’s a short-period windswell, so it’s not going to have the punch or shape you’d want. The afternoon is pretty much a write-off with the same conditions.
The real story is a bit of a ramp-up into the second week. From Wednesday the 12th, the swell ticks up a notch, hitting 3ft from the WNW by Thursday the 13th with a combined energy of 218 (moderate). The wind is still cross-off from the N and NNW at 12-16 mph, which will keep the surface clean, but the quality is still described as poor. The size is still small enough for beginners, but it's not going to be a classic Supertubos day.
The standout period looks like it’s shaping up for the last few days of the forecast, around the 17th and 18th. On Monday the 17th, we’ve got a 4ft swell from the WNW with a period of 9 seconds and a combined energy of 240 (moderate). The wind is still cross-off from the N, but it’s a fresh breeze at 19 mph. That’s a strong wind, so while the waves will have a bit more push, the surface will be a bit choppy. Still, this is the most size we’ve seen and it’s a few days out, so keep an eye on it. It’s not a classic tube machine, but it’s the best on offer.
For the rest of the run, it’s a snooze-fest with small waves and moderate to strong winds. The swell direction is mostly from the W/NW, which is the optimum for Supertubos, but the size and consistency just aren’t there. There’s no real standout session to get excited about, but that Monday the 17th afternoon is the one to watch if you’re desperate for a paddle.

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.
