The Lowdown
Alright, let me tell you what I’m seeing for Ribanceira. The next couple of days are looking pretty ordinary, but there’s a light at the end of the tunnel with a couple of windows that could be worth paddling out for.
Right now, through the middle of the week, the swell is small and the conditions are just average. We’ve got a little 3 to 5 ft southerly swell running through Tuesday and Wednesday, but it’s not very inspiring. The best of this early stretch is Tuesday morning with a light offshore breeze and a clean 3 ft S swell (combined energy is 250), but it’s just surfable, nothing to get excited about. Wednesday morning remains clean with a light SSW offshore, and the swell bumps up to 4 ft, but the period drops to a short 7 seconds, so it’ll be a bit crumbly and lack push.
Thursday the 17th through to the 22nd September is pretty much a write-off. We’re looking at onshore winds and poor surf, with the swell dropping to almost nothing by the 21st and 22nd – barely a ripple. That’s a solid four or five-day gap of real no-go conditions.
Then, Wednesday the 23rd September is where it gets interesting. That morning, Ribanceira gets a clean, moderate offshore wind from the SW, and a solid 6 ft SSE swell rolls in with a short period of 8 seconds. Combined energy is 547, so it’s got some moderate grunt. It’s not huge, but it’s the best looking day in the whole period, and it should offer some fun sandbank waves. It’s a standout morning.
After that, we get a bit of a drop-off and mixed winds. Friday the 25th morning has a gentle offshore and a 3 ft ESE swell, but it’s very ordinary again.
Now, keep an eye on Monday the 28th September. This one is promising but it’s a week and a half out, so don’t book the trip just yet. Monday morning, the wind goes glassy and we’ve got a 7 ft S groundswell, period around 9 seconds. Combined energy hits 725 – solid moderate energy. That’s gonna be a bigger, powerful swell, possibly too much for beginners. It should hit the sandbars with some good shape. However, by the afternoon it jumps to 10 ft, which is expert territory, and the wind goes a bit cross-shore, making it less appealing.
The rest of the run into the end of the month is mostly messy with onshore or cross-onshore winds and junky surf.
The water temp at Ribanceira is about what you’d expect for this time of year, so no need to worry about a wetsuit if you’re used to the local conditions.
To sum it up: your best bet is the morning of Wednesday the 23rd September for a decent, clean session on that chest-high southerly swell. The glassy, bigger swell on Monday the 28th September could be a cracker if the forecast holds, but treat that as a hopeful long-range call.

Information about the Ribanceira Surf forecast
The above surf forecast table for Ribanceira provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ribanceira can be found by selecting the local surf guide option on the grey menu. Our Ribanceira 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 (Ribanceira) 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 Ribanceira 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.
