The Lowdown
Alright, let’s talk about Adraga.
Honestly, for the next two weeks, we’re looking at a pretty tough stretch of surf. There’s a lot of energy moving through, but the wind is just going to be a constant pain in the arse, especially for a setup like this that’s exposed. We got a lot of north in the wind, which is going to put a chop on just about everything we see, and that’s going to make it hard to find anything clean.
There’s a small window to start on Saturday morning. The sea glassed right off, with a light 3ft swell rolling in from the WNW at 9 seconds. It’s weak energy, only 121, but it’s the cleanest it’s going to be for a while. You’ll get a few fun ones if you’re frothing, but it’s not going to be anything to write home about.
After that, the wind kicks up from the north and it’s mostly cross-onshore junk. The swell fills in a bit, and on Sunday we get a better pulse of 4ft from the NW with a 12-second period, and the energy jumps up to a solid 517. That’s got some push to it. But the 12-18 mph north wind is just going to murder the surface. It’s going to be lumpy and messy. This is more of a kite-surfing kind of day. You’d be fighting the paddle for nothing.
It stays like that through the start of the next week. The swell stays in the 4ft to 5ft range with moderate to fresh north winds. The energy gets even stronger – we’re seeing values over 700, like on Monday morning and again on the 10th. But again, it’s all cross-onshore and choppy. The wave quality is just poor. Too much wind, on-shore, and it’s breaking all over the place.
The wind backs off a touch on Friday the 11th, but the swell drops with it, and it’s still cross-on with a shorter period.
There is one interesting blip in there. On the 15th, a new longer-period swell shows up. We’re talking 4ft from the NW, but it’s got a 15-16 second period, and the energy values are massive – 644 and 784. That’s real groundswell. The problem is, the wind is howling from the north at 28 mph that afternoon. It’s just going to be a complete washing machine. If that wind had been offshore, it would have been a day to remember, but as it is, it’s just another day to give the ocean a miss unless you’re a kite surfer.
The whole second week is mostly this same story – fresh northerly winds and increasingly poor surf. By the 17th, the swell is dropping off.
Finally, as we get to the 18th and the morning of the 19th, there are a couple of flickers of hope. On the 18th, we get a clean, light ENE cross-off wind with 2ft of WNW swell. It’s small, but the surface is clean. Then on the 19th, it goes glassy early with a slight 2ft swell. You might get a few little lefts if you’re lucky, but it’s tiny.
So, overall, the standout moment is that glassy Saturday morning, and perhaps the clean but small sessions on the 18th and 19th. Everything else is just battling the wind. It’s a long, disappointing run. The water temp is 68°F, which is just about average for this time of year, so that’s not a problem, at least.
Keep an eye on it. It tends not to stay this bad for long and forecasts can change, but for now, don’t get your hopes up too much.

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.
