The Lowdown
Alright, this is Rusty checkin’ in from the local stretch. Let’s have a look at what’s cookin’ over the next couple of weeks.
Right off the bat, the first few days are a write-off. We’re talkin’ tiny, weak, and messy. From Saturday through to the middle of the week, the swell is barely a ripple, and the winds are all over the shop – cross-onshore, onshore, and just plain ugly. The energy is weak, often two-digit numbers (like 20 to 272), and the waves are barely a bump. The water temperature is sittin’ at 67°F with a positive anomaly of 1°F, so pretty much right where it should be for this time of year, nothing wild.
Now, Wednesday morning the 5th of August, we get a little flicker of hope – glassy conditions, 3ft swell from the SSE at 10 seconds, and the energy is a modest 145, but it’s surfable, just ordinary. That’s the only bright spot for a few days.
Then we hit a real dry spell. Thursday and Friday are still poor, with the wind swingin’ back to nasty. The next real sniff of action comes on Saturday the 8th of August. The afternoon looks promising: 8ft swell from the S, period around 8 seconds, clean offshore winds from the SSW, and the energy jumps to 973. That’s moderate wave energy, and it’s a solid setup. This is a clean, punchy wave for the crew who know what they’re doin’ – it’s borderline for beginners at that size.
Sunday the 9th of August keeps the momentum. Morning has 7ft from the S, 10 seconds, gentle offshore wind from the SSW, and energy at 906. Clean, lined-up, and proper. The afternoon holds up but the wind picks up a notch, so the morning is the call.
Now, the real standout window: Monday the 10th of August. Morning is the pick of the first week. You’ve got 7ft swell from the S, 10 seconds, clean offshore wind from the SW, and the energy is a strong 1554. This is very good surf – well-shaped, plenty of push, and the wind is perfect. The afternoon is also solid, a bit bigger at 8ft, cross-off, but still clean. If you’ve got a day to burn, this is it.
Tuesday the 11th of August gets a bit tricky. The swell is still up at 8ft from the S, with a long period of 14 seconds – that’s proper groundswell energy. But the morning has a light cross-onshore wind, and the afternoon turns onshore. That long period stuff at a sandbar can be a bit shifty and walled up, so it’s for the experienced only. The energy is huge at 2698, so there’s plenty of grunt.
The middle of the week calms down again. Wednesday and Thursday are smaller, cleaner in parts, but nothing to write home about. Friday the 14th of August has a nice morning window with 5ft, offshore wind, and clean conditions – a solid session for the everyday surfer.
Then we roll into the second week, and the confidence drops a bit, but the models are hintin’ at a ripper. Saturday the 15th of August: morning shows 10ft from the S, 9 seconds, offshore wind from the SW, and energy at 1540. That’s a big, powerful swell, but it’s only for the hardcore crew – beginners stay well clear. The afternoon gets a bit messy with cross-onshore, so the dawn patrol is the go.
Sunday the 16th of August looks like another cracker. Morning has 8ft from the S, 12 seconds, clean cross-off wind from the west, and energy at 1693. That’s very good, clean, and powerful. The afternoon holds up but the wind cranks from the south, so it’s a bit more choppy.
So, overall: the first four days are a total bust. Then we get a brief, ordinary window on Wednesday the 5th, followed by a few more flat days. The real action fires up from Saturday the 8th through to Monday the 10th, with Monday morning being the absolute standout. The second week has a couple of big, powerful days on the 15th and 16th, but treat those as promising, not locked in. The crowds at Ribanceira can show up sometimes, so if you score a clean morning, you’ll be stoked.
Rusty, out.

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.
