The Lowdown
Right, let’s have a look at what’s on the cards for the next sixteen days. The first real call falls on the morning of Saturday the 22nd of August.
Saturday the 22nd kicks off a solid run. Morning at Ribanceira (sandbar) has a clean 8ft south swell, period a short 10 seconds, with a gentle offshore breeze out of the southwest. The water here is 67°, which is pretty normal for this time of year. That first session packs a good punch of energy (1048) and it’ll be clean. The afternoon goes a bit cross-off, still surfable but not the pick.
Now, Sunday the 23rd morning is where it gets real nice. Glassy conditions, 7ft south swell, period stretching to 11 seconds. That’s a proper groundswell feel. The energy's moderate (1022) and the lack of wind makes for a clean, lined-up sandbar. Afternoon turns on even more, with 8ft and a 12-second period on a cross-off breeze – that’s a lot of wave face and power (1522). Both sessions look excellent.
The standout of the whole run is clearly Monday the 24th morning. The swell jumps to a solid 10ft from the south, period hitting 14 seconds – that’s a long-period groundswell, pushing proper energy through the water (3253). It’s clean offshore from the west-southwest. This is one for experienced surfers only – too much power for beginners. It’ll be hollow, fast, and demanding. The afternoon gets a bit messy with a cross-shore breeze, so make the dawn patrol.
Tuesday the 25th and Wednesday the 26th see a shift. The wind goes onshore and choppy, and the quality drops off hard. Tuesday morning has a 7ft south swell but it’s cross-on and weak. Wednesday is a write-off with moderate onshores and lumpy conditions.
From Thursday the 27th of August through to the end of the month, it’s mostly small and poor. A few clean moments on the 28th morning with a small 2ft south-southeast swell and a cross-off breeze (138 energy), but it’s only just surfable.
There’s a real lull until Tuesday the 1st of September. That afternoon, Ribanceira gets a surprise: a clean 7ft southwest swell with offshore wind, period a short 7 seconds (500 energy). It’s not perfect but it’s suddenly surfable again. Wednesday the 2nd morning keeps it going with a 5ft southwest swell, clean and offshore (617 energy).
After that, it tails off back to small and ordinary through to the end of the outlook. A few glassy mornings with barely any swell, and a lot of choppy onshore days.
If you’re picking one day, it’s Monday the 24th of August, dawn. That 10ft, 14-second groundswell with offshore wind is the big dog of this window. Just make sure you’re ready for the size.

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.
