The Lowdown
Alright, this is Rusty comin' to you from the beach. Let's talk about the next couple of weeks at Ribanceira.
It's a bit of a mixed bag, but there are some proper moments to get excited about. The water temp is sitting at 66°F, which is pretty much spot on for this time of year, so no surprises there.
The first real window of opportunity opens up on Sunday the 6th. Saturday morning offers a small, glassy 3ft wave from the S, but it's the Sunday morning session that starts to look interesting. We've got a clean 6ft swell from the SW, with offshore winds. The combined energy is moderate (481), but it's a step up. The swell period is a short 8 seconds, so it might be a bit bumpy and won't have that long-period push, but it's solid. The swell gets bigger into Sunday afternoon, hitting 10ft, but that's getting big and the cross-offshore wind will make it a handful. Stick to the morning.
Monday the 7th is a standout. The morning is clear with a light offshore wind from the SW and a solid 6ft south swell (529). The period ticks up to 10 seconds, which gives the waves a bit more shape and power. This is the best call of the early week. The afternoon turns a bit messy with a cross-onshore wind, so get in early.
The middle of the week is pretty quiet. From Tuesday the 8th through to the 14th, it's mostly onshore, small, or just ordinary. There are a few moments of glassy conditions on the 9th and 10th, but the swell is tiny, under 3ft. It's a bit of a lull, so don't get your hopes up.
Now, the real gold is waiting for us. Thursday the 17th. This is a proper pulse. Look at Thursday morning: a clean 8ft SW groundswell with a long period of 16 seconds and offshore winds. The combined energy is massive at 2868. This is heavy, powerful, and for experienced surfers only. The swell direction is S, which is a good match for the spot's optimum. It's a long-period groundswell, so it will be better shaped and hold up well, but you'll want to be on a step-up board. The afternoon is still solid with a 7ft, 15-second swell, but the wind is stronger, a fresh offshore. This is the standout of the whole forecast, but it's a full week and a half away, so keep an eye on it.
The energy drops back down after that, but Friday the 18th still has a solid 5ft, 13-second swell with offshore wind in the morning, and the 19th has a clean 4ft, 12-second wave with a light offshore. A nice way to wind down.
So, overall, the best surfs are Monday the 7th morning for a solid, clean session, and then the big one on Thursday the 17th morning for the experts. The middle of the forecast is a long gap of small and messy days, so plan around those two windows.
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.
