The Lowdown

Alright folks, Rusty here. Let's look at the surf ahead for Ribanceira. It’s a bit of a mixed bag, so let's break it down day by day.

The start of the period is pretty flat and messy. Wednesday afternoon the 9th has a little 3.9ft south swell, but with light rain and a cross-offshore breeze, it’s not going to be anything to write home about. Water temp is 63.5°, which is running a bit colder than normal for this time of year, so you’ll want the rubber. The swell energy is weak at 390, so don't get your hopes up.

Thursday the 10th and Friday the 11th are basically write-offs. The wind is onshore or cross-on, and we’re looking at small, weak swells in the 2ft to 3.6ft range with poor conditions. Not worth paddling out for. We'll see a bit more energy Thursday afternoon, hitting 509, but it's still poor.

The first real highlight pops up on Saturday the 12th. The wind swings offshore from the southwest, and the swell jumps to 8.2ft from the south with a 10-second period. The energy jumps to a strong 1286, and it's looking clean. This is the most promising surf in the early run, but 8.2ft can be a handful for beginners. The Saturday afternoon session brings even more energy at 2204, but with that power comes a bit of a cross-off wind, so it might get a little more challenging.

Things go downhill again on Sunday the 13th and Monday the 14th. The wind goes onshore and the swell drops, with short, weak periods or east swells mixing things up. It’s all pretty poor, so you can give those days a miss. Tuesday the 15th is a bit better, with a clean 3.6ft to 4.9ft south swell and good winds. Energy is moderate at 434 to 617. It's a good, clean option for a surf, but not a standout.

The big one is brewing for Wednesday the 16th. The morning session has 8.2ft of south swell with a strong offshore wind, clean conditions, and a big energy reading of 1106. But the afternoon is where it goes off. The swell jumps to a solid 11.5ft from the south, with a long 13-second period and a big energy reading of 6411. This is the standout of the entire forecast. It’s going to be big, powerful, and for experts only. This is the day you’ve been waiting for. The break is a sandbar, and with this size, it could be a beast.

Thursday the 17th has a nice glassy morning with 6.6ft of south swell and a 12-second period. It’s a high-quality option after the big Wednesday, but the wind shifts onshore in the afternoon and kills it.

After that, it's mostly a drag. We're looking at a run of poor to marginal conditions from Friday the 18th through the middle of the next week. There might be a wave on Sunday the 20th with some easterly swell pushing 6.9ft, but it’s got a cross-on breeze, so it’s not going to be clean. Tuesday the 22nd has a small, clean south swell push at 3ft with a very long 14-second period, but there isn't much energy behind it, and the afternoon wind goes onshore. After the 16th, nothing really comes close to that level of quality. There is a small clean window on the 24th, but it's nothing special.

So, the clear standout is the Wednesday the 16th afternoon session. Big, powerful, and clean, it’s the one to plan for. If that's a bit too much, the Saturday morning the 12th or the Thursday morning the 17th are your best bets for something big but a touch more manageable. The rest is mostly waiting and watching the wind.

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.
