The Lowdown

Alright folks, Rusty here. Let’s get into it for Ribanceira. We’ve got a real mixed bag over the next two weeks, but there are some moments that’ll get the blood pumping.

The first spot of interest is Saturday morning, September 5th. It’s not a standout, but it’s where we start. You’ll find a small 3ft southerly swell, with a period of 9 seconds – a bit of a weak push, with moderate energy (209). The wind is light and offshore from the WSW, which is a positive, keeping things clean. The water temp is sitting at 66°, which is pretty normal for this time of year. It’s surfable, but it’s not the session you’ll tell your mates about.

Things pick up quickly. Saturday afternoon sees the swell bump up to 5ft from the south, still with a 9-second period, but the energy jumps to a solid 563. The wind shifts to a cross-offshore from the south, and we’re looking at clean, good conditions. This is a nice little window.

Sunday the 6th brings a bigger pulse. The morning has an 8ft south swell with a short 8-second period, driven by a strong but clean offshore wind from the SW. The energy is up there (829). This is a serious step up – 8ft is getting into expert territory, so if you’re not comfortable in that size, sit this one out. The afternoon stays solid at 8ft, but the period lengthens to 10 seconds, and the energy skyrockets to 1347. The wind is cross-offshore, which keeps it clean, but the power is notable.

Monday morning, September 7th, is a real highlight. The swell drops to a more manageable 6ft, but it’s a clean, long-period 10-second south swell, with moderate energy (518). The wind is a light offshore from the SW – glassy, clean conditions. This is your best bet for the first week. The water is still around 66°, no anomaly to speak of. It’s a solid, fun day for intermediate surfers.

After that, we hit a dry spell. From Tuesday the 8th through Saturday the 12th, the surf really drops off. The swell gets small, the wind turns onshore or cross-shore, and the quality goes downhill. It’s a real lull – about five days of flat to poor conditions.

Then we get a second pulse. Sunday the 13th brings a new 5ft to 6ft swell from the east-southeast, with a fresh offshore wind. The energy is strong (998 to 1245), but the periods are only 10 seconds. It’s clean, but the wind is a bit strong, making it a little choppy.

The real standout for the whole forecast is Monday, September 14th. We’re looking at an 8ft to 8ft swell from the SE and ESE, with an 11-second period. The energy is huge – 2887 in the morning and 2424 in the afternoon. The wind is offshore and moderate to gentle. This is powerful, long-period groundswell, and it’s going to be breaking big and clean. This is expert-only territory. The swell direction (SE/ESE) is a solid match for Ribanceira’s optimum (S), so it’ll wrap in nicely. If you’re an experienced surfer, this is the session to circle.

Tuesday the 15th is still decent, with a 6ft to 6ft ESE swell, but the wind goes glassy in the morning and then turns light cross-on in the afternoon. The energy is moderate (910). It’s not as clean as Monday, but still surfable.

From Wednesday the 16th onward, the swell fades again. We get a few small pulses, like Thursday the 17th with a 3ft to 3ft long-period (15-16 seconds) SSE swell, but the wind is onshore or cross-shore, so the quality suffers. The following days are mostly poor, with onshore winds and dropping swell.

So, the two standouts: Monday morning, September 7th for a clean, fun, intermediate session with offshore winds, and Monday, September 14th for the big, powerful, expert-only groundswell. The 14th is the one that’ll be remembered.

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.
