The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this 16-day window for Supertubos is a tough one to call. We’ve got a whole lot of nothing on the cards for the better part of the next two weeks. The swell energy is just not there, and the wind, while often clean, is mostly cross-off or cross-shore, but it’s fighting against tiny, weak waves. The water is a bit colder than normal for this time of year, sitting at 65°, which is about 2° below average – noticeable but not insane.
The first real chance at anything rideable doesn’t show up until Friday, July 30th, and even then it’s a real struggle. Through the whole period, the wave heights are stuck under 2 ft, the combined swell energy is weak (mostly under 40, with many days barely registering 9 or 10), and the periods are short, mostly 8-10 seconds, which means weak, crumbly waves. The score is zero across the board, so there’s no standout. The best you could hope for is a tiny, clean, waist-high wave on one of the cleaner mornings, like Friday, July 24th or Sunday, July 26th with a light NNW breeze and cross-off winds, but it’s a real micro-surf session. Honestly, for paddle surfing, it’s a write-off. If you’re a kiter, those cross-off winds on the 24th and 25th (Friday and Saturday) with 15-22 mph breeze might be worth a look, but the waves are barely there.
The tail end of the period, Tuesday, July 28th morning, shows a tiny 1 ft swell from the NW with a 16-second period, which is a very long period groundswell. That’s interesting, but with such a tiny height, it’ll be a rare, clean, straight-breaking wave at the beach break – more of a novelty than a session. The combined energy is only 38, so weak. For the rest, from now until July 30th, it’s a long flat spell. There’s a massive gap of about 10 days with no real surf on offer. The only bright spot, if you can call it that, is a glassy, flat morning on Monday, July 27th – perfect for a swim, but not a wave in sight.
Bottom line: Supertubos is not on. A blank run like this is normal for the area when the summer doldrums hit. The setup here looks more interesting for kite surfing than paddle surfing on a few days, but for a surf, you’re better off waiting for the next pulse.
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.
Supertubos is 2 km (1 miles) from Peniche. If you plan a holiday in Peniche, look for hotels and other accommodation in Peniche. Peniche has rooms for a wide range of budgets as well as car hire and transport links.
