The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Ribanceira over the next couple of weeks.
Right off the bat, Monday morning (24 August) is a proper standout. Ribanceira is serving up a solid 8ft swell from the south, with a long 14-second period – that’s proper groundswell energy. The water’s sitting at 66°, which is pretty much spot on for this time of year. The wind is light offshore from the southwest, so the surface will be clean. This is excellent, powerful surf, but that size makes it one for experienced surfers only. The combined swell energy is pumping at 3029 (strong to very strong). The afternoon holds up too, with a cross-off breeze, but the morning is the pick.
Tuesday (25 August) sees a drop in size to 6ft, but the wind turns onshore and messy by the afternoon. Not your best day. Wednesday (26 August) bumps back up to 7ft with a long 14-15 second period, but again, onshore winds spoil the party. Thursday and Friday (27-28 August) are a write-off with poor conditions and the swell fading fast.
We hit a real quiet patch from Saturday the 29th right through to the end of the month. The swell drops to nothing – like 0.7ft to 1ft – and despite some glassy or offshore moments, there’s just no wave energy to work with (combined energy as low as 16). It’s a gap of several days with nothing worth paddling out for.
Now, looking ahead, there’s a glimmer. On Tuesday the 1st of September, things wake up again. Morning brings a clean 8ft from the south with a moderate offshore wind (20 km/h from the southwest). The combined energy is 1150 (moderate to strong). This is another one for the experienced crew – solid and clean. The afternoon holds similar size but with a cross-off wind.
After that, the swell hangs around the 5ft to 7ft range through the first week of September, but the wind is mostly onshore or cross-onshore, making conditions ordinary at best. The glassy morning on Friday the 4th of September offers a chance at 4ft, but it’s not a standout.
Overall, the clear winners are Monday the 24th of August and Tuesday the 1st of September. Both mornings deliver solid, clean south swell for those who can handle it.
Stay stoked,
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.
