The Lowdown

Right, folks, Rusty here checkin' in for the local line-up. It’s been a bit slow on the action front, and this forecast is a bit of a mixed bag. We’ve got a 16-day window, and the first few days are pretty flat, so don't expect to be dragging your board down to the beach just yet. There's a gap with basically no real surf worth talking about until we hit the second week. Let’s unpack it.

First up, the water temp at Supertubos is sitting at 66°F, which is a bit colder than normal for this time of year, so you’ll be wanting that full suit for sure.

For the first week, from the 6th through to the 12th of September, it’s dead. We’re talking tiny, weak slop and cross-off winds from the north. The energy is barely registering, with values like 186 (weak) on the 6th and dropping down to almost nothing over the following days. The swell is small, the period is short, and there’s not a single decent window. Save your energy and do something else.

Now, things start to get a bit more interesting on the 13th of September. Supertubos gets a pulse of 4ft groundswell from the NW, with a period of 13 seconds, and the combined energy jumps to 369 (moderate). The wind on the Sunday morning is a light offshore from the NE, with only a slight air. That’s the standout in this entire outlook. The swell direction (NW) matches up nicely with the optimum (SW), and while the report says “fairly consistent”, the offshore wind will make it clean. It’s a good one for advanced surfers – the 4ft is manageable. After that morning, the wind turns cross-off on Sunday afternoon, so the window is short.

The days following that pulse are a write-off again. The 14th has some energy but poor conditions, and the rest of the week is tiny windswell. By the 17th of September, the wind goes glassy, but the swell is only 0.7ft, so it’s a lake.

On the 21st of September, we get another little pulse of 4ft from the NW, with a 9-second period. The energy is moderate (266). It’s a morning session with a light cross-off from the ENE, and the report calls it "surfable but very ordinary." It’s not going to be a classic, but it’s something to wet a line.

So, the bottom line: The only true stand-out is the morning of the 13th of September at Supertubos. Get it, it’ll be clean, the swell is solid, and the offshore breeze is a gift. The rest is flat or average. Don't hold your breath for the second week; it looks pretty slim.

Later, 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.
