The Lowdown
Alright, grab your board. Let’s have a look at Ribanceira over the next couple of weeks.
First thing you gotta know – the water’s sitting at 64.4°, about normal for this time of year, so nothing wild there.
We’ve got a bit of a quiet start. Tuesday the 21st and Wednesday the 22nd are basically a write-off – tiny waves, poor conditions, not worth paddling out. You’re better off waxing your board and waiting.
Then, things kick off proper on Thursday the 23rd. The standout here is Thursday morning. We’re looking at a solid 8.2 ft swell rolling in from the south with a 9-second period. That’s a fair bit of juice – combined swell energy is pumping at 1752 (strong). Winds are light offshore from the southwest, which means clean faces. This is the pick of the bunch for the whole period. It’s got your name on it if you’re comfortable in overhead surf. Thursday afternoon drops a bit to 6.9 ft, still clean, but not quite as good.
Friday the 24th is a step down – 5.6 ft, but the wind is onshore and the conditions are a bit ordinary. Mixed tides might mess with it. Saturday the 25th brings back some hope: 4.9 ft in the morning with cross-offshore winds, and by Saturday afternoon we get 4.6 ft with gentle offshore wind from the southwest – clean lines, glassy in places. Nice and fun.
Sunday the 26th is another standout. Morning session sees 7.5 ft from the south with a 9-second period and gentle offshore winds – combined energy is huge again at 1800. That’s proper. Afternoon drops to 5.2 ft, not as clean but still rideable.
From Monday the 27th through to the end of the month, it’s a long quiet spell. Wind’s mostly onshore or cross-onshore, wave heights drop below 3.3 ft, and the energy is low. You’ll be chasing shadows.
Into August, still quiet. A little bump on August 3rd and 4th with waves around 2.0 to 3.3 ft, but the winds are offshore and it’s clean – surfable but nothing to write home about. The 5th picks up a bit of swell from the south at 5.2 ft with a long 13-second period, but the wind is cross-onshore, so it’s messy.
Bottom line: the best days are Thursday the 23rd and Sunday the 26th. Get on it then. If you’re not out there Thursday morning, you’re missing 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.
