The Lowdown

Alright folks, Rusty here. Let’s take a long, hard look at what’s on the table for the next couple of weeks. Gotta be straight with you – this is a tough one. There’s a big ol’ gap of flat, poor conditions staring us in the face, so we’re going to be patient.

We’re starting off with nothing. The first real chance of anything surfable doesn’t show up until Saturday morning, the 5th of September. Even then, it’s a bit of a tease. The swell is tiny at 2.6 ft from the WNW, with a short period of 9 seconds, so the energy is weak (101). The saving grace is that the wind is glassy. That’s a major positive. It’ll be clean, but you’ll be hunting for scraps. Sunday morning, the 6th, sees a similar story: 2.6 ft NW swell, still weak energy (100), and a cross-off breeze. It’s surfable, but it’s very ordinary.

Then we hit a real dry spell. From Sunday afternoon right through until the 14th of September, it’s pretty much a write-off. The winds are up, the swell is either tiny or just junk. It’s a long gap of nothing to get excited about.

Now, for the one true standout in this whole forecast. It’s fleeting, but it’s worth circling on your calendar. Monday morning, the 7th of September at Supertubos (Portugal). The swell jumps to 4.6 ft from the WNW, with a solid 12-second period. That’s proper groundswell energy, and you can feel it in the numbers – 554 (combined energy). The direction is a good match for the break’s optimum from the SW. The wind is a cross-off from the N at 16 mph, which should keep it reasonably clean. This is a big, powerful beach-and-reef setup, so that 5 ft+ swell is pushing into the experienced surfer territory. For the advanced crew, this is the window. The afternoon is similar, with 4.9 ft WNW swell and 575 energy, but still that stiff cross-off wind. It’s not perfect, but it’s the only real punch of size we get.

After that pulse, it fades fast. By Tuesday the 8th, we’re back down to 3.9 ft and the energy drops off (261). The wind stays strong and cross-off. The rest of the week is a slow bleed into flatness. By the 18th of September, we’re looking at a tiny 0.3 ft swell from the SW with a very long 15-second period, but the energy is only 10. Not worth paddling for.

So, to sum it up: the best on offer is the Monday the 7th. Get on it if you can handle the size and the crowd that’s *sometimes* there. The rest of the 16 days is mostly a waiting game.

Stay salty.

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.
