The Lowdown
G'day, Rusty here, and I’ve got the lowdown on our local stretch for the next couple of weeks. It’s going to be a bit of a mixed bag, with some solid potential but plenty of wind to dodge.
The first real call to get stoked about is for the morning of Saturday the 14th of September. Adraga’s looking good with a clean, clear sky and a light cross-off breeze from the east. Swell will be a clean 3ft out of the north-west, and the energy’s moderate (284). The water’s sitting at 66°, which is a good two degrees colder than what we’d normally expect this time of year, so a decent wetsuit is the go. That morning session should offer some fun, well-shaped waves.
Now, the following week gets a bit gnarly. From Tuesday the 16th right through to the end of Friday the 19th, we’ve got a big pulse of north-northwest swell pushing through – we’re talking 8ft to 10ft waves. The energy readings are high (1441 to 2179), but the wind is going to be strong and cross-onshore from the north, making it a messy, lumpy mess. Honestly, with those conditions and those big, blown-out faces, this setup looks far more interesting for kite surfing than paddle surfing.
The standout window kicks off on the morning of Saturday the 19th of September. The wind swings around to a light offshore from the east-southeast, and while the swell is still a solid 8ft out of the north-west, the period jumps up to a very long 14 seconds. That kind of energy is best suited for a reef or a point break, and the tide and wind should be favorable. It’s going to be big, powerful, and well overhead—definitely not one for the beginners. For the experienced crew, this is the one to circle. Expect some truly excellent waves.
Sunday the 20th, the morning session stays clean with an offshore ESE breeze and the swell settling a bit to 5ft. Energy is still decent (741). Monday the 21st and Tuesday the 22nd mornings also offer clean conditions with light offshore or cross-off winds, with consistent 4ft-5ft north-west swell. These are all good, surfable mornings.
After a quieter patch with small, ordinary surf, we get one more promising run. On the morning of Friday the 25th of September, a clean 5ft west-northwest swell rolls in with a proper long period (14 seconds) and a light offshore breeze from the east-southeast. The energy’s high (999), and the conditions look clean—that morning’s a solid bet.
The very last morning of the outlook, Saturday the 26th of September, offers a glassy start with a 4ft west-northwest groundswell. It’s clean and calm, another good option for a relaxed session.
To sum it up: the best of the best is the morning of Saturday the 19th for those who can handle the size and power. If you want something a bit more manageable, the mornings of the 21st and the 25th are your sweet spots.
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.
