The Lowdown
Alright, let’s talk Ribanceira. It’s a sandbar break, fairly consistent, and it’s a bit sheltered from the south. Water temp is about normal for the season.
The first real window is Monday morning, September 7th. Clear skies, a light offshore breeze from the southwest, and a solid 6ft south swell with a 10-second period. Moderate energy (551). Clean and glassy. By afternoon, the wind flips east and it gets cross-on, so morning is the move.
Tuesday and Wednesday are nothing special. Cross-on winds, small swell. Wednesday morning goes glassy with a 4ft south swell, but the energy is weak (331). Just average. Thursday gets a long-period 4ft south swell (15 seconds, energy 513), but it’s cross-on and cloudy with rain.
Friday and Saturday are flat and messy. A few days of nothing worth paddling for.
Then Sunday, September 13th, hits. A big 8ft swell from the SSE, moderate 11-second period, offshore wind from the south, and strong energy (1555). That’s expert territory. Clean, cross-off breeze. The sandbar might make those long-period waves a bit straight, but it’ll be clean. Monday morning drops to 7ft with cross-on wind, so Sunday is the standout.
The next week has some gems. Tuesday, September 15th, morning: 5ft southeast swell, gentle offshore from the southwest, moderate energy (541). Clean and punchy. Thursday, September 17th, morning: 6ft south swell, light offshore, strong energy (827). Another clean, fast session.
The end of the run gets ragged. Friday, September 18th, has a big 8ft south swell with a very long 12-second period and very strong energy (1631), but cross-on wind and rain. Saturday is similar. Sunday, September 20th, drops to 2ft but with a solid offshore breeze, so a clean, small day.
Best bets: Sunday, September 13th, morning for the big, clean, expert stuff. And Thursday, September 17th, morning for a cleaner, more manageable 6ft with offshore wind. Get out there.

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.
