The Lowdown
Alright folks, it's Rusty here. I've had a look at the numbers for the next 16 days and I gotta be straight with you – it's a tough one. Supertubos is a world-class wave, a beach and reef setup that usually pumps, but the forecast is showing nothing but poor surf conditions across the entire period. From now through to early August, every single session is rated a zero. There's just no standout, no day to get excited about.
The water temp is sitting around 66°F, which is about average for this time of year – nothing unusual there. But the swell? Barely a whisper. Most days we're looking at 1 ft to 1 ft from the WNW with a short period of 8–10 seconds. The combined energy is mostly in the teens or twenties, which is weak. There's one morning on the 25th of July with a 3 ft NW swell but the period is only 5 seconds – that's windswell, not groundswell, and the wind is a fresh 19 mph cross-off. Still poor. The winds are generally cross-off or cross, which keeps the surface clean, but without any real swell, it's just a flat lake.
There are a few glassy moments on the 28th and 31st of July, but with zero swell, it's not surfable. The only tiny pulse shows up on the 1st of August – a 0.3 ft, 16-second period from the west – but the energy is a measly 5, and the wind is onshore soon after. Honestly, if you're looking for a paddle, you're out of luck.
Now, Supertubos is usually fairly consistent, so this blank run is a bit of a surprise. It won't stay poor forever – forecasts can change – but for the next 16 days, there's nothing to recommend. If you're a kite surfer, maybe those cross-off days with a bit of breeze could be fun, but for a surfboard, it's a no-go.
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.
