The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Honestly, I gotta be straight with you – this is a tough one. We’re looking at a real long stretch of flat, small, and just plain poor surf. The overall pattern is a big, fat nothing-burger for the first ten days or so. From Sunday the 16th all the way through to the end of Thursday the 22nd, the swell is tiny, mostly around 0.3 ft to 2 ft, and the energy is weak, with combined energy values barely cracking 100 (like 11 to 79). The winds are mostly cross-off or cross-on, and even when it’s glassy the swell just isn’t there. There’s absolutely no recommendation for a surf in this whole first block.

Then we hit the weekend. Sunday the 23rd shows a little pulse. The swell picks up to 3 ft in the morning from the WNW with a period of 9 seconds, and by the afternoon it’s 4 ft from the same direction, period 8 seconds. The combined energy gets up to 120 and 178 respectively – that’s moderate energy finally. The wind holds as cross-off from the NNW, so it’s clean. But even then, the wave comment says “poor surf conditions.” It’s just not enough to get excited about.

After that, Monday the 24th onwards it drops back into the gutter. Swell back to 0.3 ft or 2 ft, energy crashes, and the winds are either cross or cross-off. The whole thing just fizzles out. By the end of the month, from the 30th of August, there’s no swell height at all – zero. A total flat spell.

So, what’s the standout? There isn’t one. There’s no single session that rises above the rest. The only break in the whole area is Supertubos, a beach and reef setup that’s fairly exposed to the SW, which is the optimum direction. The water is about average for this time of year. But for the entire 16-day window, every single forecast is a score of 0 out of 10. It’s a rare, blank run for this region. The only glimmer is the pulse on Sunday the 23rd, but even that is described as poor. It’s a real bummer, but sometimes the ocean just shuts down.

Keep your eyes on the charts, but for now, I’d say grab a beer and watch the sunset.

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.
