The Lowdown
Alright, Rusty here again, but this time in feet and knots. Let’s break it down.
Honestly, it’s a grim outlook for the next two weeks. We’re starting with a real dry spell. From Wednesday the 5th of August all the way through to Tuesday the 11th of August, the surf is just flat and poor. We’re talking tiny ankle-to-knee-high waves, maybe 1 to 2 feet, with a weak, short-period swell out of the west-northwest. The wind is cross-offshore, so the surface is clean, but there’s zero power. The combined energy is in the dumps, reading between 19 and 87 – that’s weak, barely enough to ruffle the surface.
Then, on Wednesday the 12th of August, we finally get a little bump. The swell picks up to about 3 feet, still from the west-northwest. The morning is your best bet, with a light cross-offshore breeze and clean faces. The combined energy jumps to 129 (moderate), so there’s a bit more push. But it’s nothing special – just surfable, ordinary conditions. The water temp is 19°, which is about normal for this time of year.
But then the wind really kicks in. From Thursday the 13th through to Tuesday the 18th of August, the north and north-northwest wind is screaming at 20 to 25 knots, with gusts higher. The swell either disappears or gives us a tiny, long-period leftover from the southwest (0.3 feet, with periods of 15 to 18 seconds). That’s a ghost wave for a beach and reef break like Supertubos. The combined energy is pathetic, sitting between 9 and 17. That’s not surfable.
There’s a small window on Tuesday the 18th of August afternoon. The swell builds to about 3 feet from the northwest, with a period of 9 seconds, and the combined energy hits 153 (moderate). But the wind is still howling at 15 to 20 knots from the north, so it’s going to be choppy and messy. Not worth paddling out for.
The only real standout, if you want to call it that, is the morning of Wednesday the 12th of August. Supertubos is a beach and reef break, fairly exposed, and the optimum swell direction is southwest. The swell we’re getting is west-northwest, so it’s not a perfect match, but with 3-foot waves and light cross-offshore wind, it’s the only window where you might pick off a few clean ones. Expect crowds – it’s Supertubos, so it’s usually busy. For the rest of the 16 days, you’re looking at a lot of down time. Better luck next week.
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.
