The Lowdown
G’day, Rusty here, lookin’ at the next couple of weeks at Ribanceira. This sandbar set-up is tucked away, sheltered from the main swell, so it’s not gonna be a constant smash-fest, but there’s a real window of opportunity when the stars align. The water’s sittin’ at about 65°, which is pretty much bang on average for this time of year, so nothin’ wild there.
The first solid action we see is Monday the 7th of September. There’s a 6 ft south swell rollin’ in with a solid 10-second period and a combined energy of 578 (moderate). Cross-on ESE wind at 6 mph is a bit messy, but it’s light, so it’s rideable. The forecast calls it marginal, but there’s a wave to be had.
Tuesday the 8th is a write-off with strong onshore winds, so skip that.
Wednesday the 9th morning is where it gets interesting. The wind drops to glassy—3 mph from the SSW—and you’ve got a 4 ft south swell, 10-second period, energy at 315 (weak to moderate). It’s small, but clean. That’s your first real chance for a fun, uncrowded session.
Thursday the 10th and Friday the 11th are poor, with onshore winds and rain. Not worth paddlin’ out.
Saturday the 12th is a big one. The morning brings a 6 ft SSW swell, but it’s short period at 8 seconds, with a fresh 19 mph offshore wind. That’s clean, but the short period makes it a bit junky. Energy is 420 (moderate). The afternoon is the real story: a 10 ft south swell, 10-second period, energy at 2268 (strong). That’s a solid pulse, but the wind is cross-off at 19 mph, so it’s gonna be blown out, choppy. This one’s for the experts only—over 8 ft is big, and the wind will make it a battle.
Sunday the 13th morning is the standout of the whole run. A 10 ft south swell, 12-second period, energy at 2599 (strong to very strong), with a gentle 9 mph offshore wind from the SSW. That’s clean, powerful, and lined up. This is excellent surf for experienced surfers. The afternoon drops to 8 ft with cross-shore winds, still good but not as clean.
Monday the 14th is a write-off with heavy rain and strong onshore winds. The swell is still there, but it’s blown out.
Tuesday the 15th is a ripper recovery. The morning has a 5 ft SE swell, 12-second period, energy at 776 (moderate), with a light offshore wind. Clean, fun, and good quality. The afternoon is the same story. Good surf for intermediates.
Wednesday the 16th morning is glassy, dead calm, with a 3 ft SE swell, 12-second period, energy at 432 (moderate). That’s a perfect small-wave day—clean, long lines. The afternoon turns onshore, so it’s short-lived.
Thursday the 17th is ordinary, with a bit of a cross-off wind and short period swell. Not great.
Friday the 18th morning is another clean window. 4 ft south swell, 12-second period, energy at 568 (moderate), with a light offshore wind. Good, clean surf.
After that, it’s a sad run. From Saturday the 19th right through to Tuesday the 22nd, it’s mostly onshore winds, rain, and tiny swell. There’s a flicker of hope on Tuesday the 22nd morning with a 4 ft south swell and a moderate offshore wind, but the period is short at 7 seconds and energy is low at 211. It’s surfable, but ordinary.
Overall, the best on offer is hands-down Sunday the 13th morning. That 10 ft south swell with offshore wind is a genuine session for the crew who charge. The second best is Tuesday the 15th morning—clean, solid, and fun for everyone. The rest is a mixed bag of small windows and blown-out days.
Rusty out.

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.
