The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for Ribanceira over the next couple of weeks.

The next 16 days are a bit of a mixed bag. We've got a few windows of clean, surfable waves, but there are also some real duds in between. Nothing huge is jumping out as a flat-out classic, but there are a couple of sessions worth marking on the calendar.

Things start off pretty ordinary this Friday afternoon, September 11th. There’s a small 2ft south swell with a long 11-second period, but the WSW wind is bringing in moderate rain and overall the conditions are pretty average. Not one to get excited about.

Saturday the 12th is a little better, but it’s a tale of two halves. The morning has a 5ft south swell with a short 6-second period, and the SSW offshore wind at 12 mph is keeping things clean. The combined energy is moderate (226). It’s surfable, but that short period means the waves will be a bit weak and choppy. The afternoon sees the swell bump up to 6ft from the south, but the wind swings cross-offshore and the wave quality drops off – poor surf conditions.

Sunday the 13th is similar. Solid 4ft SE swell, but the period is still short at 8 seconds. The morning has a clean offshore wind from the SW, so it’s okay for a paddle, but nothing special.

Now, Monday the 14th is the first real standout. The morning has a 4ft south swell with a nice 11-second period, and it’s glassy – dead flat with an ESE breeze at just 3 mph. The combined wave energy is strong (411). This will be the cleanest surf of the first week, with well-shaped, fun waves. If you can get out there Monday morning, that’s your ticket.

Tuesday the 15th morning has some punch, with a 6ft east swell and a clean offshore wind from the SW. The energy is very strong (662), which is a big number for this spot. That said, the period is only 8 seconds, so while it’ll be chunky and fun, it won’t have that grindy groundswell quality. Still, it’s a worthwhile session.

The rest of the week from Wednesday the 16th through to the weekend is mostly average to poor. There’s a brief moment of glassy conditions on Thursday the 17th morning with a 4ft south swell, but the period is short again. The following days are plagued by cross-onshore winds, onshores, or just small, weak swells. The 19th and 20th are particularly small.

The next real event pops up a week later, on Friday the 25th. This is a big one. The morning glassy conditions with a 8ft south swell (short 7-second period) and the combined energy is very strong (574). That’s a lot of water moving, and it’ll be big enough to be experts-only territory. The afternoon really pumps up to 10ft from the south with a 9-second period, and the energy skyrockets to 1598 – very, very strong. The wind is a moderate cross-offshore, so it’ll be clean, but this is for experienced surfers only. It's a long-range call, so keep an eye on it. The following Saturday the 26th looks a bit messy with onshore winds and a big swell, so that might be one to skip.

All in all, set your alarm for Monday the 14th morning for a guaranteed fun session, and keep an eye on Friday the 25th if you’ve got the skills for a serious, clean, big-wave day. The water's about average for this time of year.

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.
