The Lowdown
Alright, Rusty here, checking out our local stretch. Got to be straight with you: the next couple of weeks are a mixed bag, with a whole lot of waiting before things get properly interesting.
We're starting off on a rough patch. The first few days are going to be pretty ugly to look at, let alone surf. We've got a lot of bump and chop on the water with these cross-onshore breezes just tearing the place up. The swell is there, but it's messy and short-period, coming out of the west and northwest with a period around 7-9 seconds. The energy is moderate, but it's not doing us any favors. Think more whitewater and flying spray than clean faces. On Thursday, the combined energy is around 573 to 613, but honestly, it's just a mess. Not a day for a paddle, more a day for a coffee and a grumble.
Now, here's a flicker of hope. On Friday morning, the wind just dies completely—we're talking glassy conditions—and the swell settles into a much longer period groundswell from the WNW at around 11 seconds. The wave energy jumps way up to 1176, which tells you there's some real power there. The forecast likes it a lot, but there's a big, fat catch: the swell is forecast to be just over 7 feet. For a spot like Adraga, which is pretty exposed and a beach and reef setup, that's a lot of water moving. It's going to be heavy and powerful, probably a bit too much for a lot of people. It's a serious session for serious surfers only. This is the standout of the entire window, but it's a challenging one. The water temp is about 68°, which is pretty average for this time of year, so a slightly cool start but nothing crazy.
The rest of that weekend and the start of next week is a write-off, to be honest. The wind swings around to the north, and it's just cross-on and lumpy again. The swell drops off, but the wind keeps it junky. There's a period of a few days there where you just check the cam and decide it's not worth the hike.
Then, hold on—we've got another interesting window on Sunday, the 6th of September. Early morning, the wind is forecast to drop to nothing again—glassy, calm, perfect. The swell is back up to a solid 6 feet with an 11-second period from the northwest. The energy is strong, coming in at 794. This looks like a much cleaner, more user-friendly version of the Friday swell. The direction matches exactly what Adraga wants, which is a big plus. The forecast gives it a decent score, but not as high as Friday's. It's a promising setup, but the afternoon looks like it gets a bit onshore again, so it's a morning mission for sure.
After that, it's another slide into poor conditions. The wind comes back from the north, and we're back to chop and cross-onshore drivel. The energy drops off and the period gets short again. The second week of the forecast is pretty grim, with strong, messy north winds and small, weak, short-period swell. There's a long stretch where there's just nothing to get excited about. A couple of mornings have some light wind and a clean-ish 4-foot swell with a decent period on the 5th and 6th, but it's marginal at best. The rest of the time, it's just blowy and small.
So here's the bottom line. For the first week, the early window on the 28th of August is the big one, but it's heavy. The 6th of September morning looks more inviting for the average surfer. After that, it's a waiting game. The north wind just doesn't want to give up, and it's keeping the place onshore. It's not a stretch of water that handles that kind of wind well, and for a while, it might genuinely be more interesting for some kite surfers than us paddle surfers with those strong cross-onshore winds. Keep your eyes on those two mornings, and don't get too excited about the rest.
Rusty, signing off.

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.
