The Lowdown
Alright, let's break it down for you. We’ve got a classic pattern here – starts with a bang, goes flat, then finishes with a heater.
The opening window, from Monday morning (10 August) through Tuesday afternoon (11 August), is where you want to be. We’re looking at a clean, consistent 7 to 7ft south swell with a 12-second period. The energy is strong and the wind is either gentle offshore or glassy. That’s as good as it gets. Monday afternoon is a little less clean with a cross-off wind, but still good. Tuesday is the real standout – glassy all day, with solid energy. For a spot like Ribanceira, this is prime. Water temp is about average for the time of year.
Then it goes quiet. From Wednesday morning (12 August) all the way through to Friday afternoon (21 August), it’s mostly a washout. There’s a brief improvement on Thursday afternoon (13 August) with a 6ft swell and clean winds, and again on Friday afternoon (14 August) with glassy 5ft waves. Saturday morning (15 August) offers small, glassy 4ft waves. But the rest is a mix of onshore junk and weak, short-period dribble. That’s over a week of mostly waiting.
The pay-off comes on Friday afternoon (21 August) and into Saturday morning (22 August). Friday brings a tidy 5ft SSW swell with clean cross-off winds and very good energy. But the standout is Saturday morning: a chunky 8ft south swell, clean with a moderate offshore wind, and excellent energy. At over 8ft, this is expert territory for a sandbar break like this. The period is only 10 seconds, so it won't be the most lined-up set. Worth a look for the brave, but not a beginner's session.
After that, it fades out into the following week with nothing but onshore chop.
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.
