Alright, Rusty here. Let’s break down what’s going on at Ribanceira over these next couple weeks.
The start is a bit ugly, but we’ve got a good clean window and the tail end shapes up real nice with glassy conditions.
We’re looking at Saturday morning, July 11th, but don’t get your hopes up. Cross-on breeze, light rain, and a 5ft swell from the ESE with a 13-second period. Wave energy is moderate (722), but the wind kills it—poor surf conditions. Stay out of the water.
Sunday morning, July 12th, is the turnaround. Offshore wind from the SW at 9 mph, cleaning everything up. A 4ft S swell, 11-second period, and 703 units of energy. This is the session—clean, lined up, and you’ll be smiling. The afternoon goes cross-off, swell bumps to 5ft (991 energy), still good.
Monday morning, July 13th, stays clean with offshore wind. You get a 7ft swell from the SSW, but it’s a short 8-second period (933 energy). Punchy and a bit crumbly—best for you intermediates and above.
From Tuesday the 14th all the way through Wednesday the 22nd, it’s a long dry spell. Onshore wind, dropping swell, energy falls below 100 by the 18th. Waves between 1ft and 3ft but choppy and messy. Not worth the drive.
Thursday July 23rd morning brings a little life back. Offshore wind, 3ft S swell, 11-second period (188 energy). Ordinary but surfable. The afternoon is a touch better with 4ft.
Then the real highlight: Saturday July 25th. Morning and afternoon are glassy—dead calm wind, 4ft S swell, 10-second period. Energy is moderate (464 and 529). This is your second standout. Clean, fun, and perfect for a long session. Water temp is 60°F, which is a massive 6°F colder than average—so grab a thick wetsuit.
Sunday the 26th holds offshore wind but the swell drops to 3ft. Still surfable, just not as good as Saturday.
Bottom line: hit Sunday July 12th morning and Saturday July 25th all day. Crowds can show up here sometimes, so get in early for that glassy weekend.
See you in the water.
Rusty.

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.
