The Lowdown

Righto, let’s have a look at what’s on the cards for Ribanceira over the next couple of weeks.

First up, don’t get too excited for the opening days. From Sunday the 2nd right through to Monday the 4th morning, it’s pretty flat and messy. Tiny little 0.3ft to 1ft slop with short periods and onshore or cross-off winds. Not worth paddling out for. The surf energy is basically non-existent, sitting at just 2 to 27 (weak). These first few days are a write-off.

Things start to whisper to life on Tuesday the 4th morning. We’ve got a clean, glassy start with a 3ft S swell, period of 12 seconds, and a nice glassy wind. The combined energy climbs to 324 (moderate). It’s not world-class, but the glassy conditions will make it feel better than it looks. Wednesday the 5th and Thursday the 6th mornings offer similar, small clean waves in the 2ft to 3ft range, with glassy winds and energy between 102 and 148. These are your ‘get a few fun ones’ windows if you’re desperate for a paddle.

Now, here’s the real standout. Sunday the 9th kicks off with a solid pulse. Morning sees a 7ft S swell at 9 seconds, but the wind is dead calm – glassy as a lake. The combined energy jumps to 770 (strong). This is the first real chance for proper waves. The swell direction (S) is a touch off the optimum (S) for Ribanceira, but with that glass, it’s going to be clean and fun. It might be a bit much for beginners over 5ft, but intermediates will be smiling.

Then, Monday the 10th morning is the heavyweight champion of this forecast. We’ve got an 12ft SSW groundswell with a 12-second period and glassy wind. The combined energy is massive at 5710 (very strong). This is expert territory – over 8ft and powerful. The waves will be big, clean, and lined up, especially for a sandbar like Ribanceira. This is a day for experienced surfers only, and it’s the best on offer by a long shot.

Tuesday the 11th and Wednesday the 12th still have some decent 5ft to 7ft S swell, but the winds turn onshore or light cross-on, so the quality drops. The energy stays strong (723 to 1607), but the conditions are less ideal. Thursday the 13th sees the swell drop back to 3ft-4ft with clean offshore winds, making for a decent small-wave session.

The last few days, from Friday the 14th through Monday the 17th, fade out. The swell drops to under 2ft, the winds turn onshore or cross-onshore, and energy gets weak again (20 to 105). The 17th morning shows a 5ft E swell but with moderate cross-onshore chop – not great.

Water temp? Feels about average for the time of year, no major anomalies.

Bottom line: Forget the first few days. The gold is Sunday 9th for a fun, clean, moderate swell, and Monday 10th morning for a big, clean, powerful swell that only the experienced crew should tackle.

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.
