The Lowdown
G’day, Rusty here. Let’s cut to it—this stretch ahead is a flat spell for the most part. We’ve got a long, frustrating run of tiny or non-existent surf, and it’s going to test your patience. The good news is there are a couple of brief windows where it might just be worth paddling out, but you’ll need to pick your moments carefully.
First up, this Sunday morning (August 9th) at Supertubos (Peniche). It’s not much—only about 3ft of WNW swell, and the period is a short 7 seconds. The combined energy is weak at 84, so it’s pretty gutless. But the wind is light and cross-offshore, so the surface is clean. It’s surfable, very ordinary, but if you’re desperate for a few knee-high walls, this is about as good as it gets. The water temp is 67.1°, which is about average for this time of year, nothing weird there.
That little bump fades fast. Monday (August 10th) morning has even less—about 2.3ft of NW swell, period 8 seconds, energy at 99—same story, just smaller. After that, Tuesday (August 11th) is nearly dead with 1ft. We then hit a long, dry gap. From Wednesday the 12th through to the 20th, the swell tries to show but it’s all short-period junk and the winds are mostly fresh to strong cross-offshores. It’s not surf, it’s just bump and chop. Honestly, there’s nothing rideable in that entire stretch. If you’re a kiter, this is your time—especially around the 15th and 16th with those strong winds and tiny swell—but for a paddle surfer, forget it.
Then comes the first standout, and it’s a week and a half away. On Monday morning, August 24th, things start to look up. Still at Supertubos (Peniche), we get about 2.6ft of NW groundswell, with a proper 11-second period. The combined energy jumps to a moderate 141, which is a real upgrade. The wind is light NW, almost glassy, so the surface should be clean. This is the pick of the bunch—small but clean and with a bit more push. The afternoon builds on it: about 3.6ft from the NW, period 9 seconds, energy up to 231. The wind turns more cross-shore, so it might get a little lumpy, but it’s still the best surf we’ve seen in this entire forecast.
So, the outlook is this: a few tiny, ordinary waves this weekend, then a long, dead gap for nearly two weeks, and finally a promising but small swell on the 24th. That Monday is your best bet—worth a look, but keep expectations in check. It’s a long-range call, so it’s promising but far from certain. Keep an eye on it.
Stay patient, stay wet.

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.
