The Lowdown
Right from the start, I gotta be straight with you—this 16-day stretch for Adraga is a tough one. We’re looking at a whole lot of nothing good for the better part of the first week and a half.
The swell window is there, mostly coming from the NNW to WNW, but the wind is just killing it. Nearly every session is cross-onshore, with speeds picking up from a gentle 9 mph to a fresh 19-22 mph. It’s choppy, lumpy, and just a mess. We’ve got some energy moving through—moderate readings like 138, 142, and up to 350 in the early going—but it’s all for nothing with that wind. The swell is small, 2ft to 6ft, and short-period, mostly 6-8 seconds. This is just not surfable.
Monday the 4th has light cross-onshore and small wind ripples, but it's still not clean. The whole stretch through Thursday the 14th is a wash, with only a brief pick-up on the 11th where we see energy jump to 235, but again, it's cross-on and lumpy. Not worth paddling out for.
Now, there is one bright spot, and it’s a big one, but it comes with a major caveat. On Saturday the 16th, things change. We finally get some proper swell—the sort of size that gets your heart going. The energy just explodes, hitting 846, which is strong. Swell heights are predicted at 8ft from the NNW, with a period of 8 seconds. Wind goes light, almost glassy, with the odd 3 mph cross-on breeze. The records even say "wind and tide favorable." This is the standout, the only real window of the whole run.
But here’s the thing: Adraga is a beach and reef setup, and at 8ft with that kind of energy and short period, this is expert territory only. It’s too big for beginners, and honestly, it might be too unruly for most. It’s going to be a heavy, powerful session for the crew who know what they’re doing. The swell direction is WNW, which is right on the optimum, and the quality is there, but this isn't a day for the faint-hearted.
Sunday the 17th stays big, with 7ft to 7ft on Monday, but the wind starts to pick up again, going cross-on and cutting the quality. The energy stays strong, but the conditions won't be as clean.
So, in short: surf the 16th if you're an expert and can handle serious size and power. Otherwise, this is a blank run. It’s a long wait, but when it comes, it comes in heavy. I’ve seen this spot pump, but it needs the right wind, and we just don't get it for most of this outlook.
Water temp is sitting at 68°, which is about normal for this time of year.
Keep the faith, but maybe find something else to do for a week.

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.
