The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Well, I gotta be straight with you – the start of this forecast period is a bit of a bummer. We’re lookin’ at a solid run of days with barely a ripple. From Tuesday the 21st all the way through Friday the 24th, the surf is flat and poor. These are days for waxin’ your board and fixin’ your dings, not for paddlin’ out. The wind is mostly onshore or cross-shore, and the swell heights are stuck below 2ft with weak energy.
The first real sign of life shows up on Saturday the 25th. Supertubos wakes up with a 6ft to 6ft swell from the NW, with a period of 8 seconds. The combined energy pushes into the moderate range (326 to 354), which is a decent step up. The wind is a clean cross-offshore, which is a major positive. The waves will be clean, but that 6ft to 6ft size is right on the edge for beginners. For the more experienced crew, this is the best window in the early part of the outlook. The water temp is about average for the time of year, so no major surprises there.
After that brief pulse, it goes quiet again. The swell drops right back down to 1ft or less from Sunday the 26th through the end of the month. We’re lookin’ at a week-long gap with hardly any surfable energy. The wind stays clean from the north, but there’s just nothin’ to ride.
Now, as we push into the start of August, things get a little more interesting, but it’s still a gamble. By Monday the 3rd of August, the swell starts to build again. We see a 3ft NW swell with moderate energy (172) and a clean cross-offshore wind. The period is still short at 9 seconds, so it’ll be a bit choppy and less powerful than a proper groundswell. This is a promising signal, but we’re a week and a half out, so keep your expectations in check. Tuesday the 4th has similar energy but the swell model drops the ball, so don’t hold your breath.
So, the standout is clear: Saturday the 25th of July at Supertubos is your best bet. It’s the only window where the size and the wind line up. The rest of the 16 days is a long, flat stretch. It’s a tough run, but that’s the coast sometimes. Keep your eyes on the forecasts – things can change.
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.
