The Lowdown
G'day, Rusty here, and let's get straight into it. The next couple of weeks around Ribanceira are a bit of a mixed bag, but there are some absolute gems hiding in there if you're patient.
The first real swell kicks in on Thursday, the 13th of August. The Thursday morning session is looking like a solid standout. We've got a 7ft S swell running with a long 14 second period, and the wind is glassy out of the SW. That's going to make for some clean, lined-up waves at the sandbar. The water temp is sitting at 66°, which is about average for this time of year, so nothing unusual there. The combined energy is strong, sitting at 1576, meaning there's plenty of push. This is the pick of the early window.
The session rolls into Thursday afternoon with the wind shifting to a clean offshore from the SSW at 15 km/h, still holding that 7ft S swell, period dropping slightly to 13 seconds, but still quality. The energy is still high at 1440. This is a full day of great surf.
After that, things get a bit messy. Friday the 14th has cross-onshore winds and a drop in quality, and the weekend into the start of the following week is a write-off with poor conditions and onshore winds. There's a solid lull from Friday afternoon through to the morning of Saturday the 22nd of August.
Now, for the next standout. On Saturday morning, the 22nd of August, we get a return of decent surf. The swell is 6ft from the SSW with a 10 second period, but the wind is glassy again. The combined energy is moderate at 947. It's not the biggest, but the clean conditions will make it fun. Keep in mind the swell is shorter period, so it might be a bit more sectiony at the sandbar, but still a good morning out.
Then, the real big one comes through on Sunday the 23rd of August, but it's a tricky one. The morning shows a 10ft S swell with a 12 second period, and the combined energy is massive at 4809. That's a lot of water moving. However, it's cross-onshore at 12 mph from the NNE, making it choppy and messy. This is only for expert surfers, and honestly, the wind is going to ruin it. This setup looks more interesting for kite surfing than paddle surfing, to be honest.
The final standout is Tuesday the 25th of August. The morning session has a 7ft S swell with a long 13 second period, and the wind is clean offshore from the SSW at 9 mph. The energy is very strong at 1585. The afternoon continues with the same 7ft swell and a steady offshore wind at 16 mph, keeping it clean. This is a solid day for intermediate to advanced surfers, and the long period will give some nice, organised lines. The sandbar might get a bit straight with that long period, but the offshore wind will hold it up.
So, to wrap it up: Thursday the 13th is your best early bet, and Tuesday the 25th is the other clear winner. The rest of the time is either flat, windy, or messy. Get out there when the wind is right.
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.
