The Lowdown
Alright folks, Rusty here. Let’s be straight with you. The next couple of weeks are gonna test your patience. We’ve got a long stretch of poor conditions and small, jumbled surf ahead before things finally line up. But there is light at the end of the tunnel, so don’t put the boards away just yet.
The first few days are a write-off. Through this weekend and into the start of next week, the wind is all over the place, mostly onshore or cross-shore, and that’s going to chop up an already weak, short-period swell. You’re looking at dribbles from 0.6ft to 4.2ft with periods under 10 seconds. Not worth suiting up for. We’re going to see a gap of about four or five days with no real surf on offer, just blown-out slop.
Now, here’s where it gets interesting. The swell fills in from Tuesday the 1st of September. It’s still a bit raw with a moderate offshore breeze in the morning, but the energy is finally there. The south swell pushes in at around 7ft with a period of 7 seconds, and the energy reading jumps. It’s not perfect, but it’s a start. The wind freshens in the afternoon and swings cross-offshore, making things a bit tricky.
Wednesday the 2nd is a step in the right direction. The swell settles into a cleaner 5.6ft to 6.2ft from the south with a 10-second period. There’s a gentle offshore breeze in the morning, so the face should be clean. The energy is moderate to strong. This is your first proper window, but the standout is still to come.
Hold onto your hats for Thursday morning, the 3rd of September. This is the one. We’ve got a solid 7.8ft of south swell rolling in with a 12-second period, which means proper groundswell and real power. The energy is strong, reading high. And the kicker? The wind is glassy. Dead calm. A light breeze out of the northeast with no texture on the water. This is the best on offer, no question. Ribanceira is a fairly consistent sandbar, and when it’s glassy with a solid SW groundswell, it’s going to be firing. The size is getting up there, so it’s one for the intermediates and above; beginners will find it a handful. It’ll be onshore by the afternoon, so make the most of that morning window.
After that high, we slide back into mediocrity. The swell fades fast and the wind turns ugly again for the rest of the week and into the next. There’s a distant, long-period swell trying to show up on the 11th of September, but it’s tangled with rain and onshore winds. It’s a “maybe” at best, promising but a long way out. The energy is there, but the conditions will likely be messy.
So, to sum it up: save your energy for Thursday the 3rd. It’s the clear standout. The days around it have potential, but that glassy morning with a solid 7.8ft south swell is the one you want to plan for. The water temp is sitting at 64.2°, which is about average for this time of year, so a good wetsuit is still in order. Stay patient.

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.
