The Lowdown

Alright folks, Rusty here. Let’s get into it for the local stretch.

The next couple of weeks are looking pretty ordinary for the most part, with a lot of wind-affected surf and not much quality on offer. The good news is, there are a couple of windows that should clean up nicely, and one standout morning that looks like a real treat.

Right off the bat, we’ve got a long stretch of frustrating conditions. From Sunday the 6th right through to Friday the 11th, it’s pretty much a write-off. The wind is a persistent cross-onshore, and the surf is just a mess of lumpy, choppy, poor-quality waves. The combined swell energy is moderate (around 440 to 930), but it’s all blown out. The crazy part is that Saturday morning the 12th offers a brief moment of relief – the wind goes glassy, and the swell comes from the NNW at 4ft, but the period is a tiny 6 seconds. That’s weak, short-period stuff, and the energy is low (152). It’s surfable, but barely worth getting wet for.

Then, we hit the real gem. Sunday morning, the 13th of September. This is the one to circle. The wind is completely dead calm, glassy as a mirror. The swell switches to a proper NW groundswell with a long 13-second period, and the combined energy jumps up to a solid 708. The wave height is a clean 4ft, which is a great size for a day out. The water temperature is sitting at 68°F, which is about 1°F cooler than the average for this time of year – nothing crazy, just a little nippy for the season. For the break at Adraga – a beach and reef setup that’s pretty exposed to the WNW – this is the best it’s gonna get. With that long period and glassy conditions, the waves will be lined up, clean, and full of energy. Just keep in mind that with a period over 11 seconds, this kind of swell can be a bit tricky at beach breaks, but Adraga’s reef sections should handle it well. The crowd factor is listed as “sometimes” busy, so you might have a few buddies out, but it’s not going to be a zoo.

After that Sunday morning high, the next week is a mixed bag of more cross-onshore wind, and we see a few mornings with glassy conditions but smaller surf. On Thursday the 17th and Friday the 18th, the wind goes glassy again, with 4ft NW swell, but the period is only 10 seconds and the energy is a lot lower (around 246-330). It’s clean, but it’s not the same beast as that Sunday. Then on Saturday the 19th, the swell jumps up to 7ft from the NNW, but with a short 9-second period and a cross-onshore wind, it’s just too big and messy. The notes say it’s predicted to be too big for this break, so that’s one to skip for sure.

The final bright spot is Monday morning the 21st. The wind turns light and cross-offshore from the east, and we’ve got a clean 4ft NW swell with a 9-second period. The energy is modest (266), but the wind is clean, so it’ll be a fun, uncrowded session for anyone who can paddle out. All in all, the only true standout is that Sunday the 13th – mark it down.

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.
