The Lowdown
Alright, Rusty here. Let's have a look at what's coming our way for Ribanceira.
Right off the bat, we've got some decent energy building. The water is sitting at 67°, which is pretty much what you'd expect for this time of year – nothing unusual there.
We kick things off on Sunday the 9th, but it's a bit of a mixed bag. There's a solid 8ft swell from the south with a moderate 9-second period, and the combined energy is pumping at 2052. That's a lot of power. But the wind is a cross-offshore from the south, so it'll be a bit lumpy and tricky. This is more for the experienced crew; that size will be a handful for beginners.
Monday the 10th looks much better. The morning session is the standout for the whole period. The swell drops a touch to 6ft from the southwest, but the period stretches out to a lovely 12 seconds – proper groundswell. The wind is offshore from the southwest, grooming the sandbars at Ribanceira. This is clean, lined-up surf. The combined energy is still very strong at 1547. This is your best chance for a real good session. The afternoon holds similar size but the wind shifts to a cross-offshore, so it won't be quite as perfect.
Tuesday the 11th is another cracker. The morning is absolutely glassy with the wind swinging to the southwest at only 3 mph. We're looking at 7ft of south swell with that same long 12-second period, energy at 1495. The afternoon stays glassy with a light northeasterly breeze. Two days in a row of potential magic.
Things start to go downhill Wednesday the 12th. The wind turns cross-onshore and we get some light rain. The swell drops, the energy falls to 931, and conditions get choppy. Thursday the 13th is a write-off in the morning with cross-onshore wind, but the afternoon offers a reprieve with a cross-offshore breeze and a clean 6ft swell from the south. The energy bounces back to 1342, so there's still some punch.
From Friday the 14th through to the end of the third week, it’s pretty slim pickings. Friday morning is poor, but the afternoon goes glassy with a 5ft south swell. Saturday the 15th has some clean but weak 4ft waves. The combined energy drops right off to around 391-434. It's surfable, but nothing to write home about.
Then we hit a proper flat spell. From Sunday the 16th right through to Saturday the 22nd, it's mostly small, weak, and onshore. There are days of barely any swell, with combined energy values down in the double and low triple digits. A couple of mornings have offshore wind, but the swell is just too small (2ft to 3ft) to make it worthwhile. That's a solid week of waiting.
Finally, things start to look up again on Sunday the 23rd. We get a clean 6ft to 6ft south swell with that good 10 to 12-second period. Combined energy climbs back up near 1000. The wind is light and cross-offshore. This looks like a promising return to form, a full two weeks from now, so take it with a grain of salt but keep it on your radar.
The best bet of the whole outlook is without a doubt Monday morning the 10th and Tuesday the 11th at Ribanceira. Clean offshore winds, solid 6ft+ groundswell from the south, and tons of energy. Get on it.
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.
