The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Ribanceira.
The next few days are a bit of a mixed bag, but there's a couple of proper windows of clean surf that are worth getting excited about. The water is sitting about average for the time of year, nothing unusual there.
The standout session is Monday, the 24th of August. We've got a solid 8ft south swell rolling in with a long 14-second period, and the combined energy is a massive 3029 – that's strong, powerful stuff. The wind is light offshore from the SW in the morning, swinging cross-off in the afternoon. This is a proper groundswell, so it'll be lining up nicely, but with that size and period, it's really only for experienced surfers. The sheltered nature of Ribanceira means it'll be a bit more manageable, but don't be a hero if you're not ready for it.
After that, the window tightens up. Tuesday through to the end of the month is a write-off. The wind turns onshore and stays that way, tearing the small, messy swell apart. We're looking at a solid 5-day gap of poor conditions, so don't bother paddling out.
Now, we get a glimmer of hope. On Tuesday, the 1st of September, a new 7ft south swell with an 8-second period shows up, and the wind is offshore and clean. The combined energy is moderate at 608. It's a short-period swell, so the waves will be a bit more crumbly, but it's rideable.
But the real highlight of the second week is Wednesday morning, the 2nd of September. The forecast is for a 8ft SSW swell with a 9-second period, and here's the kicker – the wind is glassy, zero from the SW. The combined energy is a solid 1366. That's a very good chance of clean, punchy waves. It's going to be a busy one, as crowds are “sometimes”, so get in early to beat the pack.
The rest of the forecast into the second week is pretty ordinary, with onshore winds and small, weak swells. The 5th of September has a small, glassy 4ft SE swell, but it's just not enough to get excited about.
So, in short: Monday the 24th is the big one for the experienced crew, and Wednesday the 2nd of September is the one to circle for everyone else. The 2nd looks the most promising for clean, fun waves.
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.
