The Lowdown
Alright, let me look at what we’ve got over the next couple of weeks. I gotta be straight with you – the next week and a half is pretty bleak. We’re lookin’ at a whole run of flatness and junk conditions until we get to the good stuff.
Right now, there’s barely a ripple, and what little swell we do get is tiny and weak. That carries on through most of the first week. Honestly, it’s a bit of a dry spell until Sunday the 13th of September rolls around.
That Sunday afternoon things start to perk up a little. We get a pulse of swell from the NW around 4ft, period of 13 seconds. That’s got some proper energy behind it – combined energy is at a solid 514 (moderate). But the wind is coming straight from the NW, side-shore, so the wave face is gonna be a bit bumpy. It gets a marginal rating. But it’s the first real hope we’ve seen.
The next real standout and honestly the best of the whole outlook lands on Monday the 21st of September. That afternoon we get a solid NW swell pushing 5ft with a long 17-second period. That’s groundswell, boys. Combined energy jumps to 1069 (strong). The catch here though, the wind is still cross-off from the north at 19 mph. It’ll be clean, but that wind will be noticeable. Supertubos is a beach and reef setup, and long-period groundswell like this often makes for better-shaped barrels here, but it can also race through a bit. For the more experienced chargers, this is the one to circle on the calendar, but it’s a long way out, so keep your fingers crossed for a better wind forecast.
Then Tuesday the 22nd of September morning is the biggest of the whole run. Swell hits 7ft from the NW with a 14-second period. The combined energy cranks up to 1493 (very strong). That is a serious amount of water moving around. The wind stays cross-off from the north, which is good, but at 28 mph it’s blowing a gale. That’s a raw, powerful, and windy day. At 7ft at Supertubos, this is expert territory only – beginners stay well away. The afternoon drops slightly to 6ft.
So to wrap it up, the best bet on offer is the Sunday the 13th pulse for a sneaky one, but the Monday the 21st afternoon session has the quality. The water temp is about average for the time of year, so you’ll be fine in a spring suit if you’ve got one.

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.
