The Lowdown
Alright, Rusty here. Let’s talk about Adraga. It’s a beach and reef set-up over here (Portugal), exposed to the WNW, so it catches a good chunk of that North Atlantic energy. Right now, the water’s sitting pretty close to average for this time of year – nothing wild, just your standard summer warmth.
The outlook is a bit of a mixed bag. We’ve got a long stretch ahead, but honestly, the first week and a half is mostly a write-off for decent waves. From Friday the 21st right through to the start of September, it’s a whole lot of “poor surf conditions” and “marginal” calls. The wind is a real problem early on – fresh cross-onshore breezes making things lumpy and messy. There’s a pulse of swell around Sunday the 23rd, with clean conditions due to a cross-offshore wind, but the scores are low due to questionable tide. You’re looking at waves around 6ft to 6ft from the west and southwest, but it’s just not coming together right. Combined swell energy is moderate at best (864 and 824), but the quality just isn’t there.
The first real glimmer comes on Tuesday the 1st of September. It’s not huge – about 3ft from the WNW with a short period of 8 seconds – but the wind goes clean, cross-off from the SSW, and the combined energy is low (185). It’s “surfable but very ordinary,” so you’d be scraping for fun little waves if you’re desperate.
The most promising window in the whole 16-day run shapes up for Thursday the 5th of September. We’ve got swell building again, around 6ft to 7ft from the NNW, but the wind is brutal – strong onshore from the north at 25 mph. That’s going to make it messy, blown-out, and honestly, more interesting for the kite crew than for a paddle surfer. The combined energy is moderate (498-501) but those strong cross-onshore winds will ruin it.
So, what’s the call? There’s no true standout in this whole period. If I had to pick the best of a poor bunch, it’s Tuesday the 1st of September morning. The wind is clean, the conditions are surfable, and even though it’s small (3ft), at least it won’t be a washing machine. For anyone else, keep an eye on the forecasts – a blank run like this isn’t that unusual around here, but it can turn around quick. Don’t hold your breath.
Rusty.

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.
