The Lowdown
Alright folks, Rusty here. We’ve got a long look ahead at Adraga, and I’m not gonna lie to you, it’s a tough stretch. The whole 16-day window is pretty much a write-off for a proper surf session, so let's get into it.
The problem is the wind. It’s almost always blowing cross-onshore, and it’s not light. For the first week and a half, we’re looking at a constant, messy chop. The swell is there, but it’s being destroyed. On Wednesday morning, August 26th, we have a 4ft swell from the WSW with a short period of 5 seconds, and the wind is a strong 22 mph cross-shore with moderate rain. It’s a total mess. The combined swell energy is only 117, which is weak. The water temp is sitting at 68°, which is about normal for this time of year.
The pattern doesn't let up. We go through the rest of August and into September with the same story. The swell pulses up a bit, like on Friday, August 28th, with a 7ft WNW groundswell (11 second period) and a combined energy of 1042 (strong), but that NNW wind is still cross-onshore at 9 mph. The forecast even says it’s too big for this break. That’s a real kicker. For the rest of the first week, and all of the second week, it’s the same tune: fresh to strong cross-onshore winds and lumpy, choppy surf. The swell heights vary from 4ft to 7ft, but the wind kills any chance of a decent wave.
The only glimmer of hope, and I mean a tiny one, is waaaay out there. On Monday morning, September 7th, we see a 4ft swell from the NW with a very long period of 14 seconds. That’s a proper groundswell, and the combined energy is a massive 1116 (very strong). This is a long-range call, so it’s not certain, but the wind is a lighter 9 mph cross-onshore. It’s still not clean, but the period is so long it might just offer a few workable ones on the sets. Adraga is a beach and reef, and a period that long can make a beach break a bit too straight, but it’s the only thing that even gets a “marginal” rating.
Then, the very last day, Thursday, September 10th, the wind finally drops. Thursday morning shows a 3ft swell from the WNW with an 11-second period, and a light 3 mph cross-onshore wind. The combined energy is only 223. It’s tiny, but it’s the cleanest it will be all window. That’s a long wait for a small, clean day.
Honestly, there are no standouts in this window. The only dates worth even looking at the ocean are the very tail end of the forecast, around September 7th for the long-period swell, and September 10th for the light wind. But for the majority of the next 16 days, you’re better off finding something else to do. The wind is just relentless.
Rusty.

Information about the Adraga Surf forecast
The above surf forecast table for Adraga provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Adraga can be found by selecting the local surf guide option on the grey menu. Our Adraga 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 (Adraga) 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 Adraga 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.
Adraga is 9 km (6 miles) from Sintra. If you plan a holiday in Lisboa, look for hotels and other accommodation in Sintra. Sintra has rooms for a wide range of budgets as well as car hire and transport links.
