The Lowdown
Alright, Rusty here. Let's talk about Ribanceira.
The next couple of weeks are a real mixed bag. We're staring down a long, flat stretch to kick things off, with barely a bump for days. Water temp is dead average for the season at about 66°F, nothing unusual.
Things start quiet. Tuesday the 28th morning is a total wash with a weak 2ft south swell (185 combined energy) and a funky cross-on breeze. Tuesday afternoon turns glassy with some rain, but the waves are still tiny and ordinary. Wednesday the 29th has a clean offshore wind from the SW, but the swell is tiny at 2ft – not enough to get moving. Thursday the 30th morning is dead flat and glassy with a weak 2ft, short-period swell. Friday and Saturday are a complete scratch. From late Sunday the 2nd of August through Monday the 5th, it's a total desert. The swell is under 2ft, the combined energy drops to single digits, and you'd be better off cleaning the house.
We finally see a pulse of energy on Tuesday the 4th of August. The swell jumps to 4-5ft from the south, but the wind is onshore from the NE, making it a messy, bumpy affair with combined energy spiking to 448. It's a frustrating tease. This onshore junk continues through Wednesday the 5th and into Thursday the 6th, where the wind finally swings to a light offshore from the SW. The swell is a clean 3ft from the SE (263 combined energy) – finally something surfable, but still ordinary. Thursday afternoon turns glassy with a 3ft SE swell, clean but not a standout.
Now, here's the one you've been waiting for. The true standout is Monday the 10th of August. The morning kicks off with a 5ft groundswell from the south, with a very long period of 15 seconds. The combined energy is massive at 1165. Best of all, it's dead glassy. This is going to be the best of the window. The afternoon holds similar quality: 5ft at 14 seconds (1299 combined energy) and still glassy. This is proper, lined-up south swell with plenty of power and clean, windless conditions. With that long period, it'll be best wrapping into Ribanceira's sandbars. Expect longer waits between sets, but the ones that roll through will be well-shaped.
Tuesday the 11th of August is still very good, with 5ft swell at 14 seconds and glassy conditions in the morning (818 combined energy). The afternoon sees a light cross-on breeze creep in, so go for the early session. Wednesday the 12th is a drop-off again, with onshore winds returning and the quality falling away.
Short story: suffer through the first week and a half, and then absolutely be in the water on Monday the 10th and Tuesday the 11th of August. That's the real deal.

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.
