The Lowdown
Alright, Rusty here. Let's talk about Ribanceira for the next couple of weeks. It’s a slow burner to start, but there’s a couple of windows that are gonna fire.
The first few days are pretty much a write-off. The action starts to build on the afternoon of July 23rd. You’ve got a solid 8ft swell from the south with a 9-second period. The wind is cross-off, keeping things clean, and the wave energy is pumping at 904. That’s a lot of water moving. It’s a powerful swell, but at that size it’s for the experienced folks only.
The real standout is the morning of July 26th. The swell is smaller, only about 3ft from the south, but the period is a very long 12 seconds. That’s proper groundswell. The wind is a light cross-off from the WSW, and the energy is 541. This is the day for Ribanceira to show its best shape. That long period will give you clean, lined-up waves. It’s the kind of session you dream about.
We hit a bit of a lull through the end of July. The afternoon of July 30th gets interesting again with 6ft of southerly swell and glassy, flat-calm conditions. The energy is 517, and with zero wind, the ocean will be like a pond. Solid, fun-sized waves for an intermediate surfer. But the next afternoon, July 31st, is the other big day. You’ve got 6ft of swell from the SSE, a long 12-second period, and a clean offshore wind. The energy hits 941. That’s a high-quality, powerful swell with perfect wind. It’s a session for the regulars and the experts.
Into the first week of August, it gets patchier. The afternoon of August 2nd has 5ft of SE swell with a long 12-second period and a clean cross-off breeze, energy around 667. It’s a decent option, but not a standout. The days after that get smaller and more wind-affected. The end of the forecast has some promise on August 5th with a clean offshore wind and a long period, but the size is down.
So here’s the call: skip the first few days. The two days to lock in are the morning of July 26th and the afternoon of July 31st. Those are your golden tickets. The rest of the two weeks has its moments, but those two are the ones that’ll stick in your memory.
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.
