The Lowdown
G’day, Rusty here, takin’ a look at the local waves.
Honestly, it’s a tough start. We’ve got a long run of poor conditions from now through the first week or more. The wind is stiff and cross-onshore or onshore, just wreckin’ the surface. For Adraga, a beach and reef break open to the WNW, the first real chance at a surf doesn’t roll around until Tuesday morning, August 18th. That’s a dry spell of about five days where I wouldn’t wax the board.
Let’s run through it. From Thursday 13th through the weekend and into early next week, the wind from the north and north-northwest is fresh to strong, and the water is choppy, lumpy, or messy. The swell gets bigger over the weekend – Saturday 15th has 8ft waves from the NNW, but with 22 mph winds on it, it’s a messy heap. The wave energy is strong, but with those winds, it’s not for paddle surfing. Sunday 16th offers a slight break: morning has a light 9 mph cross-onshore wind with 8ft swells, and by the afternoon the wind goes onshore from the NW at 12 mph, still tough.
Now, the first sign of life. Tuesday morning, August 18th, we get a window. The wind swings light from the south at 6 mph, turning cross-offshore. The swell is around 5ft from the NNW, period 8 seconds, with moderate energy (348). It’s clean. The break is exposed, and with that light cross-off wind, it should hold nice lines. Crowds can be an issue sometimes at Adraga, so get in early.
Wednesday morning 19th is a maybe – light southerly wind again, but the swell drops to 3ft, period 8 seconds, and energy is weak (125). Just small, clean waves.
Then we hit another rough stretch. From Wednesday afternoon through to the end of the following week, the wind is back on the nose or cross-onshore, often strong. The swell sticks around, from 3ft up to 8ft, but the wind just tears it apart.
Here’s the real standout, and it’s a long-range one. Tuesday morning, August 25th – circle it. We get light southeasterly winds at 6 mph, blowing offshore. The swell is a solid 6ft from the NW, period 9 seconds, with strong energy (503). Conditions are set to be clean and the word is “expect very good surf conditions.” That’s the best of the whole 16 days. The swell direction is a good match for the break’s preference for a WNW exposure. With light offshore winds and a solid groundswell, it could be a proper day.
For beginners, any day with swell over 5ft is going to be a handful. And by Thursday 27th, the swell is forecast to be too big for the break, so that’s expert-only.
So, nutshell: a rough start, a clean but small window on the 18th and 19th, and a promising standout on the morning of the 25th. The rest you can sleep in.
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.
