The Lowdown

Alright, grab yourself a coffee, let's look at what's coming our way for Ribanceira. This is a sandbar set-up, and it's fairly consistent, which is a good start. The water is sitting at 66°, which is bang on average for this time of year, so no surprises there.

The first few days are a bit of a write-off to be honest. Monday the 31st of August has some swell around but it's a mess of light cross-onshore and rain, you're not missing much. Tuesday morning the 1st of September is slightly better, with a clean offshore wind from the southwest, but the swell is only 5ft from the ESE with a short 8-second period, so it's pretty ordinary. The energy is weak to moderate at 336. By Wednesday the 2nd though, things start to look up. We've got good conditions on the cards, with a light offshore wind from the WSW on the morning and a nice 6ft swell from the SE at 9 seconds. The energy is picking up to a moderate 454. That afternoon remains clean with a cross-off breeze, still around 6ft. This is a solid, fun day.

A quick gap follows Thursday and Friday the 3rd and 4th, with onshore winds and dropping swell, so don't bother. Then we get a run of smaller, clean days from the 5th to the 6th, nothing more than 4ft, but the wind is offshore or cross-off, so it's rideable, just small.

Now, the real standout is Monday the 7th of September. We've got a proper pulse of swell. The morning starts with a clean 7ft swell from the south at 10 seconds, and the energy is a strong 945. It builds through the day, with the afternoon clocking in at 8ft from the south, a longer 12-second period, and that energy jumps to a very strong 1447. The wind is a gentle offshore from the southwest all day, keeping it clean. This is the best session of the whole outlook. It's a bit too much for beginners, but that's a solid expert-to-intermediate wave.

The following week is a bit of a mixed bag. Tuesday the 8th starts with a cross-shore wind and a 7ft SSE swell, which is marginal. Then it's a long run of onshore winds and poor conditions from the 8th to the 10th. The 11th of September is a small, clean day, but it's nothing to get excited about. The 12th of September Saturday morning is interesting though, with glassy conditions and a 4ft swell from the east, offering a clean, if small, session. The 13th and 14th are clean but small, and the wind picks up again. The last few days from the 15th are tiny and onshore, a real fade-out.

So, if you're picking one day, it's Monday the 7th of September. That's your standout. The 2nd of September is a solid fallback, and the 12th of September morning is a wildcard for a glassy small-wave session.

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.
