The Lowdown
Alright, let’s talk about Ribanceira. We’ve got a bit of a wait on our hands, I’m not gonna lie. The first few days are a write-off, with tiny, weak swell and onshore junk. Nothing worth paddling out for at all. Thursday the 6th and Friday the 7th are really just for the kiteboarders if anything, with the lumpy, cross-off stuff on Friday afternoon getting up to 7ft but with a messy, short 8-second period and strong side winds. The water is about average for this time of year, so nothing weird there.
The real story starts to build on Monday the 10th. That’s when the south swell gets its act together. We’ve got a solid 6ft to 7ft of S swell rolling in, with a proper 11 to 12-second period – that’s groundswell, that’s the good stuff. The wind is offshore from the SW, light and clean. The combined energy is pushing into the moderate to strong range, giving the waves some real punch. This is your window. Tuesday the 11th looks even better, with that same 7ft swell and clean offshore conditions. The sets will have some push, and the long period means the waves will be well-shaped, especially for a sandbar setup like this. If you’re an intermediate, this is the one to aim for.
Wednesday the 12th holds into the morning with that same 7ft SSE swell and glassy offshore wind, but the afternoon turns a bit cross-on, so get it early. After that, it gets messy again with a lot of onshore wind and junky conditions until the 14th of August, which offers another clean window with 6ft of S swell and light offshore winds. That’s a solid option, but the real standout is that Monday-to-Tuesday run. The 20th of August is a wildcard late in the game – a clean 4ft glassy morning, but it’s so far out it’s less certain. For the consistent, quality surf, you want the 10th and 11th.

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.
