The Lowdown
Alright, let’s talk it out in feet, miles per hour, and Fahrenheit. Rusty here, checkin’ what Ribanceira’s got cookin’.
The first chance to even think about it is Saturday the 25th of July. We’ve got a small 5ft swell from the SE with a short 8-second period, but it’s glassy in the morning, no wind to mess it up. The energy’s at 304 (moderate), but the waves are just ordinary. Not worth a ticket.
Sunday and Monday drop off fast, swell under 3ft, wind goin’ cross-onshore or onshore. Messy.
Tuesday the 28th of July morning shows a 5ft swell from the NNE, but it’s got only a 6-second period, so no grunt. The wind is light offshore from the SW, so it’ll be clean-faced, but weak. Energy’s only 216 (moderate on the low side).
The real standout, the one to circle, is Monday the 3rd of August. That morning we’ve got a solid 6ft swell from the ESE, 8-second period, and the combined energy jumps to 679 (moderate to strong). The wind is dead calm, glassy as a pond – that’s a huge plus. Ribanceira is a sandbar break, fairly consistent, but expect some company. For an intermediate surfer, that Monday morning glass-off is the only true highlight in this whole 16-day stretch. Water temp is about average for this time of year.
After that, Tuesday the 4th through Wednesday the 5th of August sees the swell jump to 7ft and even 10ft, with energy readings over 1000 (strong to very strong), but the wind is howlin’ onshore from the NE at 12 to 16 mph, makin’ it a chopped-up mess. Those days are lookin’ better for a kite than a paddle.
Then it all flatlines. From Thursday the 6th of August afternoon, it drops to nothing. By the 7th and 8th, we’re talkin’ ankle-biters at 0.3ft or less. A long, flat spell to close it out.
So, Monday the 3rd of August morning. That’s your window. The rest is a waiting game.
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.
