The Lowdown
Alright folks, Rusty here. Let’s get straight into it. To be honest, it’s a pretty grim stretch coming up for Adraga. The wind is stubbornly cross-onshore or onshore for the whole sixteen days, and the wave quality is poor from start to finish. There’s no standout session here, no sneaky window of clean conditions. The best we can say is that the swell sizes get bigger, but the wind is a constant enemy.
The first few days, from Thursday the 6th to the 9th, are tiny and weak. Swell heights are under 4 ft with periods of 7 to 9 seconds, and combined energy is low, between 66 and 260 (weak to moderate). The cross-onshore winds from the NNW are a constant 16 mph, making it choppy and unrideable. Water temperature is 69°, right on the money for this time of year, not that it matters much when you’re getting blown off your board.
From the 10th of August into the second week, the swell bumps up a bit, but the wind only gets stronger. The 13th to the 15th sees some 5 ft to 6 ft swells, but the period drops to 6 seconds—short-period wind chop, rubbish. The breeze is up to 19 mph and the surf is lumpy. By the 16th of August, the swell starts to push bigger: 8 ft on Sunday morning with a period of 8 seconds, and combined energy climbing to 726 (strong). That’s real power, but with the NNW wind howling at 16 mph, it’s a messy, blown-out mess. On the 18th of August, it hits 8 ft with 8 seconds and a screaming 25 mph cross-onshore wind. The wave energy is 895 (very strong). That’s a serious, dangerous washing machine, only for the most experienced, and even then it’s ugly. The 19th and 20th keep the swell over 7 ft, with the wind finally easing a little on the 19th morning to 9 mph, but it’s still cross-onshore, so again, poor quality.
For a spot like Adraga, this is a total write-off. The setup is a beach and reef, so with this much onshore wind and strong, short-period swell, it’s honestly more interesting for the kite surfers than anyone with a paddle. If you’re desperate, the 19th of August morning has the lightest wind (9 mph), but the swell is 7 ft, still cross-onshore, and the shape will be terrible. There is no good session in this window. A blank run like this is normal for the area when the winds sit in the wrong quadrant. Forecasts can change, but right now, I’d find another hobby for a couple of weeks.

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.
