The Lowdown
G’day, I’m Rusty. Let’s talk about the surf outlook for Adraga – a beach and reef setup exposed to the west-northwest. We’ve got a long 16-day window, but honestly, it’s a pretty grim start with a whole lot of nothing on offer for the first week. The water temp is sitting at 68°, which is basically average for this time of year, so nothing weird there.
Right, first up – from Sunday the 9th right through to Saturday the 16th, it’s all cross-onshore wind and poor conditions. The swell hangs around 2 ft to 8 ft, but the wind is a mess from the north and north-northwest, constantly chopping things up. Wave energy stays weak to moderate for most of it, sitting between 95 and 141 in the early part, then building to moderate-to-strong by mid-week with energy readings like 311 and 421. By the 15th and 16th, the swell gets bigger, up to 8 ft, and the energy jumps to 934 and 940, but the wind is still a fresh onshore mess. Honestly, this stretch is a write-off for a paddle surfer – that kind of wind and size at a beach-reef setup looks more interesting for kite surfing than anything else. There’s no point even thinking about it until things change.
Now, the good news comes on Monday the 17th. That morning, things flip. The wind drops to glassy – a light SE breeze at just 3 mph – and the swell is a solid 7 ft from the NNW with a 9-second period and strong energy (832). The break’s description says the swell might be too big for this spot, and at over 8 ft it’s really only for experts, but 7 ft is still big and powerful. The wind is perfect, glassy clean. It’s a standout moment if you’re experienced and can handle it. The afternoon stays clean with a cross-offshore SSW breeze at 12 mph, swell still 7 ft. Crowds? This spot can be busy sometimes, so expect company if it looks good.
Tuesday the 18th morning keeps the run going: offshore SE wind at 12 mph, swell 7 ft from the NNW, 9-second period, energy at 694. That’s clean, strong surf, but again on the big side for this break – more for the advanced crew. The afternoon drops off a bit in quality, with a marginal forecast and only moderate energy.
Wednesday the 19th and Thursday the 20th stay in that big, clean zone with cross-offshore winds, but the swell is consistently over 7 ft, so it’s still only for those with serious skills. By Friday the 21st, we’ve got a 8 ft NNW swell with light cross-onshore wind from the west – not as clean but still powerful, energy at 998, nearly strong. That’s another big day.
Then from Saturday the 22nd onward, it fades back into poor conditions with onshore winds and chop, swell dropping to 5 ft–6 ft, and the energy weakens. No more standouts after that.
If you’re looking for the best of the whole run, lock in Monday the 17th and Tuesday the 18th. The glassy and offshore mornings, combined with strong, long-period groundswell, will be worth the wait for experts. Just be ready for a crowd.
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.
