The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at Adraga over the next couple of weeks.
Honestly, the first week and a half is a bit of a write-off for decent paddle surfing. There’s a long stretch of poor conditions with messy, cross-onshore winds hammering the place. The swell shows up, but the wind just ruins it. The first real glimmer of hope comes right at the end of the period.
The pick of the whole forecast is Monday, 14 September. That morning, the stars align. We’ve got a clean 6 ft swell rolling in from the WNW, and it’s a proper groundswell with a period of 14 seconds. That’s packing some serious energy (1331 - that’s strong), and the key here is the glassy wind. Zero wind. It’s going to be absolutely clean. The only catch is the size: 6 ft is getting up there, so it’s not for beginners, but for the experienced crew, that’s prime. The water temp is sitting about 68°, which is pretty average for the time of year, so nothing unusual there.
Before that, there are a couple of mornings worth a mention if you’re desperate. Friday morning, 4 September, has a tiny 2 ft glassy swell – perfect for a longboard but very weak energy (81). Saturday morning, 5 September, is similar with a glassy 3 ft. And then on Sunday, 13 September, we get a clean 2 ft from the WNW with a light offshore. Again, small stuff, but clean.
The Monday afternoon session on 14 September is a bit of a let-down after that glassy morning. The swell jumps up to 7 ft, which is big and powerful (1554 energy), but the wind swings onshore, making it a messy, marginal call. The Tuesday morning after that is already getting lumpy again.
So, to sum it up: the first 12 days are mostly a battle against the wind. The standout is the morning of Monday, 14 September – glassy, clean, and a solid groundswell. That’s your window. After that, the wind picks right back up and the quality drops. You’ll be kicking yourself if you miss that Monday morning.

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.
