The Lowdown

G’day, I’m Rusty. Let’s look at what’s on offer for Ribanceira over the next couple of weeks. It’s a slow start, and you’ll have to wait a bit. The first real surf worth paddling for doesn’t pop up until early next week, so there’s a gap of about five days of flat or poor conditions to sit through.

The early stuff from Sunday the 2nd through the weekend is tiny—like 0.3ft to 1ft at best—with a mix of onshore and cross-off winds that aren’t gonna make anything worth getting wet for. The water temp is 67° for the first reading, which is a touch warmer than normal for this time of year, so you won’t freeze while you wait.

The real action starts to build around Wednesday the 5th of August. Wednesday morning offers a little 3ft SSE swell, but it’s only a 1 out of 10 for quality, and the wind is a slight offshore from the SSW, which keeps it clean. The energy is weak though, at 148. Not a standout, but it’s something.

Friday the 7th is a write-off—tiny and cross-onshore, with winds up to 15 mph making a mess of things.

Then, Saturday the 8th of August afternoon brings a surprise: glassy conditions with a 4ft swell from the S, period of 7 seconds, and energy of 225. It’s surfable, but the period is short. Still, the glassy wind is a big plus.

Sunday the 9th has a morning window with 3ft S swell and a gentle offshore from the SW—clean but nothing special. The afternoon gets a 4ft swell with a 19 mph offshore, which is a bit fresh.

Now, the standout is Monday the 10th of August. Morning brings 8ft S swell with a period of 8 seconds, a gentle offshore from the WSW, and combined energy of 743. The afternoon jumps to 8ft S swell, same period, with a cross-off breeze from the SSE. This is the one to aim for. It’s big enough for intermediate surfers, but over 8ft pushes it toward expert territory.

But the real gem—the absolute best of the run—is Tuesday the 11th of August. Morning: 8ft S swell, period 13 seconds, glassy conditions with a light SW breeze, and energy of 2175. That’s strong energy, a long-period groundswell, and it’s glassy. The afternoon is even bigger: 10ft S swell, still 13 seconds, glassy with zero wind, and energy of 2774. That’s expert territory. The crowds are listed as “sometimes,” so you might have a few others out, but it’ll be worth it.

Wednesday the 12th keeps the party going with 8ft S swell in the morning, period 13 seconds, offshore from the SSW, and energy of 4039. The afternoon drops to 7ft but still clean. Thursday the 13th is also good, with 7ft S swell and offshore winds in the morning.

After that, the wind turns onshore from the ENE and NE from Friday the 14th onward, and the swell drops off fast. The conditions get messy, and by the 16th and 17th it’s tiny and choppy. So the window is tight: Monday 10th through Thursday 13th is your best bet, with Tuesday 11th being the absolute standout.

If you’re after a clean, solid wave, aim for the 11th. Glassy, long-period groundswell, and plenty of energy. Get on it.

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.
