The Lowdown
Right, folks, Rusty here. Let’s take a look at what’s been brewing for Adraga over the next couple of weeks.
Honestly, it’s been a rough run. For the first nine days of September, the wind is a constant problem – it’s almost always cross-onshore, blowing from the north, and often strong enough to make things choppy and messy. The swell is there, but it’s just not happening with that wind. We’ve got a lot of days with combined wave energy in the moderate range, like 213 on the 5th, but the surf is just poor. The water temperature is sitting at 68°F, which is about normal for this time of year, so at least it’s comfortable.
The first real glimmer of hope comes on Monday, the 14th of September. Early morning, the wind goes glassy, and we’ve got a 8 ft swell from the NNW. That’s a lot of power, with combined energy at 929. The problem here is that 8 ft is getting into expert territory for most, and the file notes this swell is predicted to be too big for this break. It’s a cruel tease – a glassy morning with a big swell that’s just too much. The afternoon sees a 7 ft swell from the same direction, but the wind switches to a gentle cross-onshore, so it’s not as clean.
Now, if you’re looking for the best of a bad bunch, put a circle around Tuesday morning, the 15th of September. We get an offshore wind from the ESE at just 3 mph, making for clean conditions. The swell is a more manageable 5 ft from the NW, with a period of 9 seconds. That’s a decent groundswell, and the energy is moderate (446). The file says "expect good surf conditions," which is rare in this outlook. It’s not a standout for the ages, but it looks like the only window where all the stars align for a proper session. Be aware, Adraga is a fairly consistent beach and reef break, so it can handle a bit of swell, but with that offshore wind, it should be shaping up nicely.
After that, it’s back to cross-onshore winds and messy conditions. There’s a huge spike on Thursday, the 17th of September, with a 8 ft swell from the NNW and combined energy of 1233. That’s a lot of water, but it’s predicted to be too big for the break, and the wind is cross-onshore again. Not for the average surfer.
So, to sum it up: the first week is a write-off with the wind. The second week has one standout: Tuesday morning, the 15th of September. Get on it if you can, because the rest of the outlook is a long stretch of poor surf and strong cross-onshore winds. It’s a dry spell, but forecasts can change.
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.
