The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at Ribanceira over the next couple of weeks.
Right off the bat, it’s pretty quiet. The first few days are a write-off, with tiny bump and barely a pulse. You’re looking at a gap of about three days with nothing worth paddling out for. Then things start to get interesting.
The real standout window opens up on Thursday, the 23rd of July. Thursday morning is the pick of the whole forecast. We’ve got a solid 8ft swell from the south, with a period of 9 seconds, and the wind is offshore from the southwest. That’s going to produce clean, well-shaped waves at this sandbar setup. The combined energy is chunky at 1426, so there’s plenty of push. This is a proper session for experienced surfers – it’s got some size, so it’s not for beginners. That water temp anomaly is about average for this time of year, so nothing unusual there.
Thursday afternoon backs off a touch to 6ft, but still clean with cross-offshore wind. Not a bad backup.
The next highlight is Sunday, the 26th of July. Another solid morning with 7ft from the east-southeast, offshore wind from the southwest again, and strong energy at 1158. Clean, powerful, and set up well for the sandbar. Again, this is for the competent crew.
Monday the 27th of July also has a good morning session: 6ft, glassy conditions, and offshore wind from the northwest. The period stretches out to 10 seconds, which will give the waves a bit more shape and make the paddle out easier. Clean and fun.
After that, the surf drops off noticeably. The rest of the week and into early August is mostly small, messy, or onshore. There’s a brief blip on Thursday the 30th of July with a tiny 2ft and offshore wind, but it’s very ordinary. The last few days of the forecast are weak and inconsistent, with only small, poor-quality waves.
So, to sum it up: the best on offer is definitely Thursday morning, the 23rd of July. Sunday the 26th is a close second. Everything else is either flat or forgettable. If you’ve got a window, make it those days.
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.
