The Lowdown
Alright folks, Rusty here, checkin’ in with the surf outlook for Ribanceira. Let’s have a look at what’s on the table.
We’re kicking off the forecast with a bit of a flat start. Thursday morning the 6th has a tiny 2ft SSE swell with a weak combined energy of just 82, and while the glassy conditions are beautiful, it’s pretty ordinary for a paddle. It’s not really worth getting excited about. The water temp sits at 67°, which is about normal for this time of year.
The real story starts to build from Sunday the 9th. That morning we get a solid 7ft S swell with an 8-second period, and the wind is offshore from the SSW at 15 mph. The combined energy is a moderate 914, and the conditions are clean. This is a proper standout. By Sunday afternoon the swell bumps up to 8ft from the S with an 11-second period, energy cranking to 2107, but it’s cross-offshore and the score is a bit more marginal. Still, the morning is the pick.
Monday the 10th is another beauty. Morning and afternoon both deliver 6-7ft S swell with 12-13 second periods, gentle offshore SW wind at 9 mph, and combined energy around 1151 to 1181. Clean, lined-up, and powerful – this is the best of the bunch.
Tuesday the 11th holds steady with 6ft S swell, 11-second period, and offshore wind in the morning. The afternoon gets a cross-off breeze, but it’s still clean. Good surf, but not quite the peak of Monday.
The rest of the week fades a bit. Wednesday the 12th has a 6ft SSE swell with 12-second period, but the cross-on wind messes it up. Thursday the 13th afternoon looks interesting with 5ft S swell and glassy conditions – that’s a sneaky clean session if the tide works out.
Then we hit a dry spell. From Friday the 14th afternoon through to Tuesday the 19th morning, it’s mostly poor conditions with onshore winds and choppy, lumpy surf. A few days there with nothing to write home about.
But hang in there, because Wednesday the 19th morning brings a clean 6ft SSW swell with 8-second period and light cross-off wind. Then Thursday the 20th morning is the real long-range standout: 6ft S swell with a long 14-second period, glassy conditions, and combined energy of 1379. That’s a classic Ribanceira morning if the wind plays ball – clean, solid, and plenty of push. Keep an eye on that one.
Overall, your best bets are Sunday morning the 9th and Monday the 10th, with Thursday the 20th morning as a promising long-range option. The sandbars here are fairly consistent, so even when it’s flat, it doesn’t stay poor for long.
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.
