The Lowdown
Alright wave hunters, Rusty here. Let’s talk about what’s shaking at Ribanceira over the next couple of weeks.
The first few days are a bit of a write-off—tiny dribble and nothing to get excited about. We’re looking at a long wait until the action finally kicks in. From Tuesday the 21st right through to Wednesday morning the 23rd, it’s all poor surf conditions with waves under 3 feet, weak energy, and mostly messy winds. You’d be better off finding a beach chair than a surfboard.
Then, Thursday the 23rd morning is where things start to wake up. That south swell pulses in at a solid 6 feet, with a period of 9 seconds and a clean offshore wind from the SW. The combined energy jumps to 940 (moderate to strong) and you’ll get proper, pushy waves. It’s not huge, but it’s certainly fun. The water temperature is about average for this time of year, so no surprises there.
The standout window is Thursday the 23rd morning through to Friday the 24th morning. Thursday morning delivers that 6 feet SSW groundswell with glassy offshore conditions—clean, lined up, and the sandbar at Ribanceira should be holding. Thursday afternoon bumps up to 7 feet from the SSE with cross-off wind, still clean. Friday morning keeps the 6 feet but with a glassy NE breeze, which is beautiful. This is the best of the run. Crowds are possible here, so get in early.
Saturday the 25th afternoon has a clean 4.6 feet from the SE with a cross-off breeze, but it’s not quite as good as the Thursday-Friday block. The week after that fades fast. From Sunday the 26th onwards, the consistency drops, winds turn onshore, and the swell loses its mojo. By the time we hit August, it’s back to flat, small dribble with strong NE winds. There is a brief spike on Wednesday the 5th of August with a 10 feet SSE swell and offshore winds, but that’s over two weeks away and the period is only 9 seconds—still, for experienced surfers only, it’s a big powerful wave. Keep an eye on that one, but don’t book your flights yet.
Overall, the pick of the fortnight is Thursday the 23rd and Friday the 24th. That’s where the magic is.

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.
