The Lowdown
Alright, Rusty here, checking out the 16-day picture for our local lineup. Let's get straight into it.
Right off the bat, we’ve got a pretty grim stretch ahead. There's almost nothing happening from now until the morning of Tuesday the 22nd. That’s a solid week of flat or near-flat, blown-out conditions. The wait will be worth it for some, but it’s gonna be tough.
The first real glimmer of hope shows up on Tuesday morning, September 22nd. Supertubos will finally see a pulse of NW swell pushing 4 ft with a 11-second period. The wind is light and cross-off from the north, which means the surface should be clean. The combined swell energy is moderate, clocking in at 429, and the water is a bit colder than normal at 65°F.
Things really ramp up on Wednesday, September 23rd. This is the standout window. Supertubos is looking at a solid 5 ft NW swell with a very long period of 14 seconds. That’s proper groundswell energy. Winds stay light and cross-off from the north, so it’s going to be clean and lined up. The combined energy jumps to a solid 961, which is moderate to strong. For a spot like Supertubos, with that SW optimum direction, the NW energy will be hitting well. This is the peak of the forecast. Thursday morning, September 24th, holds decent leftovers at 5 ft NW with a 12-second period, but the magic fades from there.
After the 24th, the wind starts to pick up again from the north, and the quality drops off quickly. There’s a bit of size into the weekend of the 26th and 27th, with swells around 5 ft and long periods, but the fresh breeze will mess up the surface. It’s a write-off for the most part.
The one true standout is Wednesday morning, September 23rd, at Supertubos. That combo of a long-period 5 ft NW swell with light, clean offshore-cross winds is as good as this window gets. Expect some proper barrels for the crew who can handle it.
Crowds at Supertubos can be a factor sometimes, so get in early.
Keep your eyes on that Wednesday call.
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.
