The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu for Adraga over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough stretch ahead. We’ve got a long run of "poor surf conditions" with nothing worth paddling out for from the start all the way through to the 22nd of August. That’s a solid gap of nearly two weeks where the wind is mainly a messy cross-onshore from the NNW and N, and the wave quality is just choppy, lumpy, and not clean. You’ll see some swell around, but the energy is weak to moderate in that period, with combined energy figures mostly sitting between 115 and 670, and the periods are short and junky. Not your friend.
Now, things get interesting right at the tail end of the forecast, but it comes with a big caveat. On Sunday the 23rd of August, Adraga lights up with a solid 8 ft swell from the NNW. The energy reading jumps to a massive 1747, so that’s a strong pulse of power. The wind that morning is a light cross-off from the S, which should clean it right up. But here’s the rub – at 8 ft, this swell is predicted to be too big for this break. This is expert-only territory. The same goes for Monday the 24th, where we see 8 ft from the NNW, glassy conditions with an ESE breeze, and another huge energy reading of 1338. Again, it’s too big for most, but if you’re an experienced local who knows the reef and the rip, those could be sessions of a lifetime. Just know the crowd might be inevitable if it’s clean.
For the average surfer, the best chance comes on Tuesday morning the 25th of August. The swell drops down to a more manageable 5 ft from the NNW, the wind goes glassy with a light N breeze, and the combined energy is a moderate 452. That’s a "good surf conditions" call. It’s a smaller window, and the period is short at 8 seconds, but with glassy conditions, you’ll get some fun, clean waves on offer. The water temp is sitting at 69°, which is about average for the time of year.
So, to sum it up: wait it out through the long dry spell. The standouts are the 23rd and 24th for the brave and skilled, and the 25th morning for a more chill, clean session.
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.
