The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s shaking for the local stretch.
The next sixteen days are a bit of a mixed bag, to be honest. We’ve got a run of pretty ordinary, choppy conditions to wade through first, but there’s a real glimmer of hope in the second week. The standouts are definitely the windows of clean offshore wind, which are few and far between. The water’s sitting at 69°, which is bang on average for the time of year, so no need for a thick wetsuit just yet.
The first week is a tough slog. Thursday afternoon the 7th of August starts off with a weak, cross-onshore 3ft swell from the NNW at 9 seconds, and it’s messy. The energy is weak (204). That’s a no-go. Friday the 8th and Saturday the 9th are tiny and onshore, not worth a paddle. We then get a few days of moderate cross-onshore winds with swells under 4ft and short periods, giving us low energy (below 200). It’s just choppy and frustrating. The pattern continues right through to the 15th of August, with the swell building but the wind staying cross-onshore, keeping the surface lumpy. The energy is climbing into the moderate range (391-427), but the quality just isn’t there.
There’s a real window of opportunity that starts to open up on Wednesday the 19th of August. The morning session at Adraga is looking promising. We’ve got a clean 5ft swell from the NW, and the wind is swinging offshore from the SE at 12 mph. The energy is moderate (262), and the periods are a solid 8 seconds. That offshore wind will be a game-changer, cleaning up the lines. It’s a fairly consistent spot, but it can get crowded sometimes, so get in early. The swell is a touch over 5ft, so it might be a little much for total beginners, but it’s perfect for anyone with a bit of experience.
Thursday the 20th of August morning is also a standout. Again at Adraga (Cascais), the swell is up to 6ft from the NNW with a light cross-offshore breeze from the SSE at 9 mph. The energy is solid (462) and the conditions are clean. This is a bigger day, over 8ft, so this is one for the experienced crew only. The waves will have some punch.
The run of clean conditions continues into Saturday the 22nd of August. The morning session is looking very tidy with a 4ft NW swell and a light offshore breeze from the south at 6 mph. The energy is good (301), and the 9-second period will give it some shape. This is a great day for a wide range of surfers, from intermediates up. It’s clean, it’s rideable, and the crowds will be possible.
Overall, the first week is a write-off. The best bet is to wait for those windows of offshore wind around the 19th, 20th, and 22nd of August. The long-range stuff is promising, but not a dead cert yet.
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.
