The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Adraga.
Right off the bat, we’ve got some good news. The water’s sitting at 65°, but that’s a solid 4° colder than normal for this time of year. You’ll want a thicker steamer if you’re heading out.
The next few days, though, are a write-off for anything decent. We’re looking at a stretch from Sunday the 13th right through to Saturday the 19th where the conditions are just blown out. It’s mostly onshore, choppy and messy, with that strong north wind ruining any chance of a clean wave. A couple of days have some chest to head-high swell, but with the wind howling cross-onshore at 28 mph on Wednesday the 16th, that’s kite-surfing territory, not paddle surfing. The energy is strong, reading 1356 on Wednesday morning, but it’s all for nothing with the wind.
Now, the first true standout comes on Saturday the 19th. That’s the one to circle on the calendar. Saturday morning is looking special. We’ve got a clean 6 ft swell from the northwest, with a long 14-second period pushing in a heap of energy (1694). The wind is light and cross-off from the northeast. This is excellent for experienced surfers. It’s a bit on the big side for beginners, but for anyone who knows what they’re doing, this is the pick of the whole forecast. Expect clean, powerful lines off the points and reef at Adraga. Keep in mind, this is an exposed spot and with a long period like that, the sets will be well-spaced.
If you miss that window, the following morning, Sunday the 20th, is also very promising. Another clean morning with a 6 ft NW swell, a 12-second period, and a light cross-off breeze from the ESE. The energy is still solid at 792, offering very good surf conditions without the raw power of the day before.
The next week looks more mixed. Monday the 21st and Tuesday the 22nd both have clean mornings on offer with some waist to chest-high swell, but the afternoons are blown out by an onshore breeze. Tuesday morning is especially nice, with 5 ft of NW groundswell and glassy conditions. Wednesday the 23rd morning is also worth a look, with a 5 ft swell and a light offshore from the southeast keeping things clean.
After that, it really fades out. From Thursday the 24th onwards, the swell drops right off and the window for anything decent closes. There’s a tiny bump of a 2 ft NW swell on Monday the 28th, but it’s nothing to write home about.
To sum it up: grit your teeth through this week, and get ready for a proper session on the morning of Saturday the 19th. That’s the best you’ll see for a while.
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.
