The Lowdown
Right, let’s have a look at Adraga for the next couple of weeks. It’s a beach and reef set-up that likes a good clean WNW swell, but the wind’s gonna be a major player here.
We’ve got a rough start, no sugar-coating it. Through to Friday the 18th, it’s all cross-onshore northerly wind, blowing 15 to 28 mph, and the waves are just messy – lumpy and choppy, not worth paddling out for. Swell’s building, yeah, but the quality is shot. There’s a moderate to strong combined swell energy (up to 1575) but with that wind, it’s a wasted ocean.
The first real standout comes Saturday the 19th morning. That early session is looking magic. Wind goes light and offshore out of the ESE at just 6 mph, and the swell is a solid 8 ft from the NW with a very long period of 14 seconds. That’s proper groundswell energy – combined energy reading 2515, so that’s strong to very strong. That’s the kind of power that draws up nice lines on the reef. But here’s the kicker: that size is too big for this break according to the forecast. So unless you’re a well-experienced local who knows where to sit, it’s going to be a washing machine. For the experts who can handle it, it’ll be a clean, memorable session. It’s really only for the advanced.
Sunday the 20th morning settles down. Swell is 6 ft from the NW at 12 seconds, combined energy 815 (moderate). The wind is light out of the ESE, cross-offshore, and the report says “expect very good surf conditions.” It won’t have the raw power of Saturday, but it’s gonna be way more user-friendly and clean. That’s your pick for the best all-round session.
Monday the 21st sees the swell drop to 4 ft from the NW with a 10-second period (combined energy 294, weak). Offshore wind early, so it'll be clean but small.
Tuesday the 22nd morning is a beauty too – glassy, with a light NNW breeze at 3 mph, and 4 ft of NW swell at 12 seconds (combined energy 403). That’s clean and fun-sized.
From Wednesday the 23rd, the wind swings more onshore or cross-onshore, and the quality drops off again – lumpy, messy, poor conditions through to the end of the month. There’s a glimmer on Thursday the 24th morning – flat calm, glassy, with 3 ft from the WNW (11 seconds, combined energy 266). That’d be a quiet, tidy little session if you’re keen.
After that, it’s more cross-onshore northerlies and a building swell again around the 26th and 27th, but it’s all side-wind slop with combined energy up to 1948. Not worth it for paddle surfing – that’s more kite-surfing territory with the strong wind and messy waves.
Crowds at Adraga can pop up sometimes, so mid-week mornings are your best bet for a bit of space.
Water temperature is sitting at 66°, which is a bit colder than normal for this time of year – you’ll feel that difference.
Bottom line: Saturday the 19th morning for the brave experts who can handle big, clean, powerful groundswell, and Sunday the 20th morning for the cleaner, more manageable session. Glassy Tuesday the 22nd morning as a decent backup.

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.
