The Lowdown
G'day, I'm Rusty, and I've been staring at the charts for Supertubos. Fair warning, it's a bit of a tough stretch ahead. The next week and a half is looking pretty flat and messy, so we’re staring down a long dry spell.
Right from the start, Tuesday morning the 1st of September is a write-off. We've got a weak 5ft swell from the NW with a short 9-second period, but it's getting hammered by a 16 mph N cross-offshore wind. The combined energy is a meager 334, which is moderate, but the conditions are just poor. It doesn't get any better through the week. We're looking at tiny waves, mostly under 3ft, with cross-offshore winds and very weak energy readings, often under 100. The water temp is sitting around 69°, which is pretty normal for this time of year.
There’s a little flicker on Saturday the 5th of September morning, but a 4ft NW swell with a 9-second period gets ruined by a light W cross-on breeze. The energy kicks up to 205, but the onshore wind kills it. The afternoon cleans up with a N cross-off breeze, but the swell drops to 3ft. It’s surfable, but ordinary.
The next real blip of hope doesn’t show up until the second week. On Monday the 7th of September, we see a long-period NW groundswell starting to fill in, with a 12-second period. The morning is a clean 3ft from the NW, but the wind is a moderate 12 mph N cross-off. The combined energy is a decent 314. The afternoon builds to 5ft from the NW, with the same 12-second period and energy jumping to 488. It’s still just a marginal forecast, but it’s the first sign of life. This one will be best for experienced surfers as it gets over 5ft, and the long period might make the beach break a bit straight, but it's the best on offer.
The week after that is a desert. From Tuesday the 8th of September through to the 14th, we’ve got nothing but zeros for swell height and energy. Complete flatness. It stays that way until Tuesday the 15th of September morning, when a 4ft NW swell with a 9-second period shows up with a light NE offshore breeze. The energy is a solid 358, and for the first time, we get an "expect good surf conditions" call. This one’s a standout for the whole 16 days. The offshore wind will make it clean at the break. It’s a decent size, but not too big for most.
Finally, Wednesday the 16th of September morning has a clean 4ft NW swell with a 10-second period and N cross-off winds, but it's only rated as marginal.
So, to wrap it up: don't bother for the first week and a half. The only real standout is the Tuesday the 15th of September morning session. It’s clean, has some energy, and is worth the wait. The Monday the 7th of September afternoon is the next best bet, but it's a long-range call, so keep an eye on it.
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.
