The Lowdown
Hey, Rusty here again. Let’s break down the surf at Ribanceira.
Honestly mate, for the first stretch it's a total no-go. There's a big, flat lull kicking off the forecast, and we’re looking at a long gap before anything worth mentioning shows up. Don't even bother with the wetsuit for now.
Alright, Sunday, August 3rd has a tiny, clean morning, but it’s still too small to get excited about. The first real glimmer of hope is on Monday, August 4th. We’re getting a swell from the S at about 4ft, with a period of 11 seconds (moderate energy of 334). The wind is a light offshore out of the SW, keeping the face clean. That’s a fun, intermediate-level wave.
Now, here’s the one you need to wait for. Circle Thursday, August 13th. That’s our legit standout. The water temp is 66°, which is pretty standard for the time of year. On Thursday morning, we’ve got a 3ft S swell with a long 12-second period (strong energy, 479). The wind is a light offshore from the SW – perfect conditions for a clean, groomed wave. The afternoon session is even better: the swell ticks up to 4ft from the same direction, and the energy jumps to a beefy 720. The wind stays offshore, so expect a picture-perfect, glassy afternoon. That’s the day.
Before that, Wednesday, August 5th has a glassy start but the swell has a short period so it’ll lack juice. The rest of the first week is a write-off, but that Thursday the 13th is the real deal. The swell direction suits Ribanceira, and that 12-second period will give the sandbar some proper, grunty lines. Expect some crowds ‘sometimes’, especially if the sun’s out, but mid-week is your best chance for a quiet lineup.
So, don't hold your breath for the near future. The whole first week is a bust. The real action is on Thursday, August 13th. That’s your day.
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.
