The Lowdown

Alright folks, Rusty here. Let's have a look at what Adraga has in store for us over the next couple of weeks. It’s a bit of a mixed bag, but there are a couple of windows that’ll get the heart pumping.

The overall pattern is that we start with a pulse of swell that gets messy fast, and then we’re staring down a long, windy, poor-quality stretch that drags on for over a week. The best bet is going to be that Monday morning session, followed by a Tuesday if you’re keen.

We’ve got some swell arriving on Sunday the 16th, but it’s ugly. Sunday morning sees a 7ft swell from the NNW with a short 8-second period, but it’s cross-on with a 6 mph NNE wind. The combined energy is moderate at 570, but it’s described as marginal. Sunday afternoon goes from bad to worse as the wind whips up to 16 mph from the NNW, blowing straight onshore. Avoid it.

Monday the 17th is where it gets interesting. Monday morning is your standout. The swell drops slightly to 6ft, still from the NNW with that 8-second period, but the wind goes glassy. That’s a massive positive. The water is about average for the time of year. The break is fairly consistent and exposed to that WNW direction, so it’ll be handling the swell. At 6ft, it’s manageable for a solid intermediate, holding at a moderate wave energy of 356. This is your call.

Monday afternoon the wind swings onshore from the W at 9 mph, and it gets choppy. Skip it. Tuesday the 18th is the second-best option. Tuesday morning sees the swell drop to 5ft, still NNW, but we get a clean cross-offshore wind from the S at 9 mph. Wave energy is down to 284, solidly moderate. The surf will be clean but smaller. Tuesday afternoon holds similar conditions. From Wednesday the 19th, the swell drops right off to under 3ft, and the energy plummets to below 150 – just a weak, weak pulse. Don’t bother.

Then we hit a long, frustrating stretch. From Thursday the 20th all the way through to the end of the month, the wind is relentless. It’s mostly cross-on from the NNW or N, blowing anywhere from 12 mph right up to a messy 25 mph. The swell tries to pick up again, like Friday the 21st morning with a 8ft NNW swell and energy of 788, but it’s blown to bits by a 19 mph cross-on wind. The wave comment calls it poor for that whole window. The setup is a beach and reef, and with those strong, lumpy winds, it’s looking more interesting for a kite session than a paddle session. This blank run lasts about eight days with nothing worth paddling out for.

Even into the final days of the month and the 31st of August, it’s the same story: strong cross-on winds and messy surf. The energy does spike back up to 550-556 on the 30th, but with that wind, it’s a write-off for a clean wave.

So, to sum it up: set the alarm for Monday the 17th morning. That glassy window is your golden ticket. Tuesday morning is the backup. After that, it’s a long wait with no real standouts.

Stay safe out there.
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.
