The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for Supertubos. It’s a pretty quiet start, so don’t rush to grab your board just yet.
We’re looking at a long stretch of nothing worth paddling out for. From Tuesday the 28th of July right through to the afternoon of the 4th of August, the swell is tiny, with heights all under 3 ft and wave energy readings stuck in the low double digits (27). The conditions are clean or cross-off at times, but there just isn’t enough ocean to work with. It’s flat, plain and simple.
The first real glimmer of hope shows up on the morning of Wednesday the 5th of August. Swell picks up to 2 ft from the WNW, period around 10 seconds, and the energy reading climbs to 104 (moderate energy). The wind is light and cross-off from the N, so the surface should be clean. But honestly, the waves are still very ordinary – just barely surfable. It’s a small step, not a standout.
We get a bit more consistency around the 10th and 11th of August. Monday the 10th sees the swell building to 4 ft by the afternoon, pushing wave energy to 206 (moderate). The wind remains cross-off from the N, keeping things clean. The morning of Tuesday the 11th is slightly better, with 4 ft of WNW swell and 281 energy, but the period drops to 8 seconds, which is short period, making the waves a bit weak and lumpy.
The best of the whole window, and the only true standout, is the afternoon of Tuesday the 11th of August. Swell hits 6 ft from the WNW, period 9 seconds, and the combined energy jumps to 480 (strong). The wind is cross-off from the NNW, so it’ll be clean. This is a solid, powerful wave for Supertubos, but keep in mind that at 6 ft, it’s getting into the size range that’s better for experienced surfers. The short period (9 seconds) means it won’t have the long, drawn-out lines of a groundswell, but it’ll have plenty of punch. The break is a beach and reef setup, so with that much energy, it could be a bit of a handful.
For the start of the second week, the morning of Wednesday the 12th of August has 5 ft of NW swell, with 309 energy, but again, it’s marginal. The winds are still offshore from the N, so it’ll be clean, but the swell is dropping.
The standout for a surfer? Without a doubt, the afternoon of the 11th. It’s the biggest, most energetic swell of the whole period, with clean cross-off wind. The break is fairly consistent and exposed to the SW swell, which fits the optimum direction. Supertubos is a world-class wave, and with this size, it’s going to be offering some proper barrels. But it’s an advanced wave on a good day, and with 6 ft, it’s not for the faint-hearted. The period is a touch short, so it’ll be a bit peaky, but the quality of the wave itself should make up for it.
So, if you’re patient, wait for that Tuesday afternoon. The rest of the run is a write-off.
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.
