The Lowdown
Alright, let’s break it down. Ribanceira is a sandbar break that’s been a bit slow to start, but there are a few windows worth paddling out for. The week ahead is mixed, but there’s one day that stands out big time.
Sunday the 13th is nothing special. We’ve got chest-high, 4ft to 4ft swell from the SSW/S with a short 7-second period, and the wind is a moderate offshore from the SW. The wave energy is weak to moderate, around 200-226. It’s surfable, but it’s pretty average.
Monday the 14th is a bit better. The morning brings a waist-to-chest-high 4ft swell from the S, but the period jumps to 11 seconds – that’s a solid groundswell. The combined energy is moderate at 473, and we’ve got a gentle offshore wind from the WSW. The water temp is about average for this time of year. The morning is clean and the best part of the day, but by afternoon the swell drops to 3ft and the period shortens to 8 seconds. Not bad, but not great.
Tuesday the 15th is small and uninspiring – 3ft to 4ft, mostly from the SE and E, with periods around 8-9 seconds. The energy is moderate (187-463), but the wind swings to a moderate cross-offshore in the afternoon. Low quality, skip it.
Wednesday the 16th gets interesting. We’ve got a head-high 6ft swell from the S with an 8-second period, and the morning is clean with a gentle offshore SW wind. Combined energy is strong at 854. That’s a solid morning session for intermediates, but the afternoon turns choppy with a moderate cross-offshore wind. Hit it early.
Thursday the 17th and Friday the 18th are a bust – onshore winds, poor conditions, small energy. Saturday the 19th is flat with tiny 2ft waves and next to no energy. The 20th is also poor with rain showers and onshore winds. A real lull.
Monday the 21st brings a pulse of head-high 6ft swell from the E with an 8-second period. The morning looks clean with a light cross-offshore wind and moderate energy at 506. A decent option for Monday morning, but the afternoon turns onshore and messy.
Then from the 22nd it goes flat again – tiny 1.0ft and 0.7ft waves – until Wednesday the 23rd when we see a return of waist-to-chest-high 5ft to 5ft swell from the S with a short 7-second period. The wind is fresh to moderate offshore, so it’s clean, but the short period keeps it from being special. Surfable but ordinary.
The Standout: Thursday the 24th is the one to mark. We’ve got a strong 7ft to 6ft swell from the S, and the period stretches to 13 seconds in the afternoon – that’s a very long period groundswell. The combined energy is very strong, hitting 1487 in the morning and 1275 in the afternoon. The wind is a moderate offshore in the morning, shifting to cross-offshore in the afternoon. This is expert territory – 7ft is too big for beginners, and with that long period, it’ll be powerful and best suited for a point break or reef setup, but Ribanceira is a sandbar, so expect some big, straight barrels if it’s breaking right. The morning is the cleanest window. This is the best on offer.
Friday the 25th still has a solid 5ft swell from the S with a 12-second period and a light offshore wind in the morning. Combined energy is moderate to strong at 556. It’s a good follow-up day, but by afternoon the onshore wind kills it. After that, it’s all downhill – small, weak, and onshore through the weekend into the next week.
So to sum it up: Wednesday the 16th morning is a solid warm-up, but Thursday the 24th morning is the clear winner. Get on it if you can.

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.
