The Lowdown
Right then, let’s talk about the next couple of weeks. The short story is it’s going to be a real test of patience. We’ve got a long, dry spell of tiny or non-existent surf ahead, before a glimmer of something better tries to show up late in the second week. For the most part, you’re better off leaving the boards in the car.
Right now, Sunday afternoon at Supertubos (Portugal) has some waist-to-chest high swell from the NW at around 4ft, with a solid 12-second period. There’s a decent amount of energy in the water (451), but the wind is howling from the WNW at 9 mph, making it a cross-shore mess. The water is a very unusual 64°, a full 5° colder than normal for this time of year, so you’ll want a thick suit. The forecast says the quality is poor, so it’s not worth the paddle.
From Monday, September 14th, right through to Saturday, September 28th, it’s almost a total write-off. There are days of flatness, and on the rare occasion a tiny 1ft or 2ft bump shows up, the wind is often strong and from the wrong direction. The combined swell energy stays well under 100 for most of that stretch, often hitting zero. There’s a bit of a tease around the morning of September 24th, with a clean 2ft NW groundswell (13-second period) and light offshore winds from the NNE. The energy is moderate (125), but it’s just too small to get excited about, and the guide calls it “very ordinary.” The morning of the 25th is similar, with a long-period 2ft NW swell (16 seconds) and clean, light cross-offshore wind, but again, just not enough size.
The only real standout in this whole outlook, and it’s a long way off, is Monday morning, September 28th. A pulse of stronger, short-period windswell from the WNW is forecast at 6ft, with a period of just 8 seconds. The wave energy will be significant at 370, but it’s coming with a strong S wind at 28 mph, making for a very messy, lumpy cross-onshore chop. At that size and with those winds, Supertubos will be a washing machine. That setup looks far more interesting for kite surfing than paddle surfing. It’s a long-range call, so it’s promising but less certain, but it’s the only time in the whole 16 days we see any real height.
Stay patient, lads. This is a blank run that’s pretty normal for the area. Forecasts can change, but for now, it’s a waiting game.

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.
