The Lowdown
Hey, Rusty here again. Let's break down the same forecast for the imperial folks.
Alright, so we're looking at Adraga. Honestly, for the first week and a half or so, it's a tough watch. The conditions are messy, the wind is almost always on it, and the swell is just not working with the break. We're looking at a lot of cross-onshore winds and choppy, lumpy waves. There's a real gap here with no good surf on offer from the start through until around the 15th of August. The energy is mostly weak to moderate, with the combined energy readings sitting in the low to mid hundreds, like 72 (weak) and 150 (moderate), which just isn't enough to clean things up against that wind.
The first real glimmer of hope comes on Sunday morning, the 16th of August. The swell is picking up to 7ft from the NNW, and the wind is light from the north at 6 mph, with just small wind ripples. The combined energy is a solid 603 (strong), which is a big step up. The comment says the wind and tide are favorable, but the swell is predicted to be too big for this spot. That's a real shame because it looks like it could be a powerful, clean wave, but it's going to be a washing machine for most, only for the experts who can handle that size. The water temp is about average for the time of year, sitting at 69°F with a tiny anomaly of 0.4°F.
Then we get a couple of days of marginal surf around the 17th and 18th, with the swell dropping to 5ft but still with that light cross-onshore wind. The energy drops back to the 300-400 range (moderate). It's a bit of a tease.
The real standout, and the one to circle on your calendar, is Friday the 21st of August. The swell is pumping at 8ft from the NNW with a 9-second period, and the combined energy is massive at 1260 (very strong). The wind is light from the west on the afternoon, a gentle breeze. Again, the comment says it's favorable but too big for this break. At 8ft, this is strictly for the experts. It's a powerful, heavy groundswell. For the average surfer, this is a spectator sport. The crowd situation? Adraga can get busy, but with this size, it'll thin out to just the chargers.
After that, the wheels come off again. The wind picks up to a strong breeze and near gale force from the 22nd, with the swell staying big but the conditions becoming a complete mess. It's blown out and not worth paddling out for.
So, to sum it up: if you're a seasoned expert, you've got a one-day window on the 21st of August to get a piece of that big, powerful NNW swell with light winds. For everyone else, this is a two-week stretch with plenty of frustration and not much to ride. The energy is just too often mismatched with the wind, and when it gets big, it's too much for the break.
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.
