The Lowdown
Alright folks, Rusty here. Let’s have a look at what's cookin' for Adraga over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough stretch. The whole 16-day window is pretty much a write-off for decent surfing. We're looking at a long, blank run here. The problem is almost constant wind. For days and days it's gonna be getting chopped up and lumpy, with the ocean feeling like it's got the grumps.
We start on Tuesday, 25th August. It’s a cloudy morning with a gentle 9 mph cross-onshore wind, and there's some small 5 ft swell at 7 seconds. The water is 67°, a touch colder than average for this time of year. But honestly, the wave quality is poor. That afternoon clears up, but the wind stays, making for messy conditions.
Wednesday the 26th brings a risk of thunderstorms and a moderate breeze. The swell tries to push to 5 ft later in the day, but it's a short-period bump and the wind has it looking choppy. No good.
Thursday the 27th is a write-off. Rain showers and a fresh 19 mph cross-onshore wind. The swell is building to 7 ft, but the energy is just getting torn apart. It’s lumpy and messy.
Friday morning the 28th is the only flicker of hope in the whole outlook, but it's a complicated one. The swell hits a solid 8 ft from the WNW with a long 11-second period. The combined energy is strong (1447). The wind is a light 9 mph cross-onshore from the NNE. For a spot like Adraga, which is a beach and reef setup, that long period swell can break a bit straight, but the main issue is that 8 ft is getting up there – pretty much expert territory. The forecast notes it's a bit big for this break. If you’re a seasoned charger and you can get a drop on one of those bigger sets before the wind picks up, you might find a bomb. But be warned, the crowds at Adraga are sometimes an issue. The afternoon is a mess again with a fresh 22 mph blow.
From there, it's a grim slog. Saturday 29th through to the end of the run on Wednesday 9th September is just a repeat of the same story: moderate to strong north and north-northwest winds, cross-onshore, with a lumpy or messy ocean. Swell sizes bob between 3 ft and 7 ft, but the wind is just never your friend. Even when the swell period stretches out to 11 seconds on the 2nd, the wind is on it, and it's a "poor surf conditions" call again.
So, the only real standout, if you can even call it that, is that early Friday morning the 28th. It's a powerful, long-period groundswell, but it's big, the conditions are only just about rideable, and it's really only for the experts. Everything else is a no-go. A blank run like this is a bummer, but it happens. Keep your eye on the charts; it can't stay this windy forever.
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.
