The Lowdown
Alright, Rusty here, let's get into it.
First off, the next week and a half is looking pretty grim for Ribanceira. We’ve got a solid stretch of poor surf, with onshore winds and messy conditions dominating the charts. The first few days are a write-off, with Wednesday the 26th offering a 8ft swell from the SSE, but that 18 mph onshore wind is just going to shred it. You’d be mad to paddle out. Things stay ugly through to the end of August, with a mix of onshore and cross-onshore winds and small, weak surf. The wave energy is low, reading between 10 and 93 (combined energy), which is barely a bump.
The real hope is September 1st. That Tuesday morning, the wind swings offshore from the SW, cleaning things up. We’re looking at a 8ft swell from the SSW, which is a solid size. It’s a bit much for beginners, but for intermediates, this is the pick of the whole forecast. The wave energy is strong at 731 (combined energy). The swell period is short at 8 seconds, so it’ll be a bit lumpy and disorganised, but with that clean offshore wind, it’s the best we’ve got.
Following that, Wednesday the 2nd morning is also good, with a 7ft SSE swell and a light offshore breeze from the SW. The energy is solid at 897 (combined energy). And then Thursday the 3rd morning is looking glassy, with a 6ft swell from the S and a slight air from the SSW. That’s a 10-second period, so it’ll have a bit more shape and hold. The wave energy is moderate at 599 (combined energy). These three mornings are the only real windows.
The water temp is about average for the time of year, nothing unusual to report there.
After that, the surf drops off again. Friday the 4th through to the 10th sees a return to onshore winds and small, messy conditions. The swell on the 10th is 8ft from the SSE, but the wind is cross-on from the NNE, so it’s a no-go. The whole run is a flat spell for Ribanceira.
So, in short: the first week is a write-off. The standout is the morning of September 1st with that 8ft SSW swell and offshore wind. The 2nd and 3rd of September mornings are also worth a look. Don’t bother with the rest.
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.
