The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up for Ribanceira.
It’s a slow start, no two ways about it. The first few days are a bit of a write-off, with tiny, weak swell and the wind just not playing ball. We’ve got a gap of pretty much nothing worth chasing from Tuesday the 28th through to the morning of Tuesday the 4th of August. The energy is just too low, and the wind is messy. Hold tight.
Things start to look a little more interesting from Tuesday the 4th. The swell picks up to 3.3ft to 3.6ft from the south, with a moderate 263 units of energy behind it. The wind is calm or light cross-off, so the surf will be clean. It’s still ordinary, but it’s a step in the right direction.
Now, the standout period. The morning of Wednesday the 5th of August is where it really kicks off. You’re looking at a solid 5.6ft south swell, with a beefy 853 units of energy. The wind is dead calm – glassy. That’s a proper session. The water temp is sitting at 65.5°F, which is dead average for this time of year, so nothing unusual there.
But the real highlight, the one you want to circle on the calendar, is the morning of Tuesday the 11th of August. We’ve got a 5.6ft south swell, but this one is a groundswell with a very long period of 14 seconds. The energy is massive at 1436 units. The wind is light offshore out of the southwest, so it’ll be clean. This is a serious swell for Ribanceira. It’s a sandbar set-up, so that long period might make it a bit straight, but with that wind and that size, it’s going to be the best on offer. The surf will be good enough for stronger intermediates, and the crowds at Ribanceira can be a thing sometimes, so get there early.
The following morning on Wednesday the 12th carries that energy through with 5.6ft, 14-second swell and glassy conditions, but the afternoon gets a bit dicey with onshore wind. Thursday the 6th sees a shift to a 3.9ft SSE swell, but the wind is cross-on, so it’s not as clean.
Overall, the first week is a dud, but the second week has some real firepower. That Tuesday the 11th is the standout.

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.
