The Lowdown
Well, folks, it's a tough one to call this time. I'm looking down the barrel of the next 16 days and honestly, it's a bit of a desert out there. We've got a solid 16-day window ahead, but it’s looking like we're in for a long, dry spell.
Right now, and for the next couple of weeks, the surf is just not cooperating. The wind is a persistent problem. It’s onshore or cross-onshore from the north for days on end, which is just messing everything up. The water temp at Adraga is sitting at about 68°F, which is pretty normal for this time of year, so you can't blame the water. The real story is the wind and the lack of any decent swell.
The first few days, from Monday the 31st of August right through to the end of the first week of September, are all "poor surf conditions" with the combined swell energy hovering between weak and moderate, around 62 to 504. The swell is mostly from the NW, but it's getting hammered by a fresh to strong breeze. It's going to be lumpy, choppy, and just not worth the paddle out.
We then roll into a long gap. From the 1st of September all the way through to the 13th, there's just nothing. Day after day of cross-onshore winds and weak, disorganized swell. The energy is low, the periods are short, and the conditions are just plain ugly. It's a solid stretch of nothing.
Now, there is a hint of a change. On Sunday the 13th of September, we see a slight shift. The wind is light from the SW, and the swell is from the west, but it's still only a marginal forecast. The combined swell energy is a modest 250. It's a glimmer, but not a green light.
The best of a bad bunch, if you can call it that, comes on the 13th of September morning. For Adraga, a beach and reef break that's exposed to the WNW, the swell is a weak 3 ft from the west, with a 9-second period. The wind is light from the SW, which is a cross-shore, and that's about as clean as it's going to get. It's a marginal surf situation, but it's the only thing that even gets a score of 1 out of 10. It's a long shot, and it's only for the truly dedicated.
The rest of the second week is more of the same. Onshore winds, weak swell, and poor conditions. It's not looking like we'll get any real quality until the very end of the period, and even then, it's a long shot.
So, my honest advice? If you're a kite surfer, the strong winds might make this period interesting, but for a paddle surfer, it's a write-off. The forecasts can change, but right now, there's nothing to get excited about. Hang tight, and maybe pull out the wax for a skateboard instead.

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.
