The Lowdown

G’day, Rusty here, looking at what’s on the cards for Ribanceira over the next couple of weeks. The water’s sitting at 64°, just a touch cooler than the norm for this time of year, nothing too wild.

The first few days are a bit of a write-off, I’m not gonna lie. Tuesday afternoon the 8th has a weak 4ft south swell, but it’s cross-on and messy, wave energy is low (315). Wednesday morning the 9th goes glassy, and you’ll see a cleaner 4ft south swell rolling in at 10 seconds, with decent energy (376), but it’s just surfable, nothing special. That afternoon, the wind shifts cross-on and the combo drops off. Thursday and Friday are mostly a dud – small, onshore, or poor conditions. You’re looking at a gap of flat, poor surf until...

Saturday morning the 12th. That’s your first real standout. Offshore SW wind at 15 mph, and a solid 8ft south swell with a 10-second period. The energy is pumping (1401). This is a powerful, clean wave – not for the faint-hearted, over 8ft so it’s expert-only territory. The afternoon gets even bigger at 10ft south-southwest, cross-off wind, and energy is cranking (4046). This is big, clean, and lined up. If you’re experienced, this is the window.

Sunday morning the 13th is still firing, with a 6ft south-southeast swell, light offshore SSW wind, and moderate energy (558). Clean conditions. Afternoon goes cross-on and messy again.

Next standout is Tuesday morning the 15th. Offshore SW wind again, 8ft east swell, and energy is strong (1321). Clean, powerful, and a bit more forgiving than the 12th – still a good size for intermediates with some experience. The afternoon holds at 6ft with the same offshore wind.

Wednesday the 16th afternoon has a 6ft south swell, clean, cross-off wind, and a decent energy reading (846). Good, clean fun.

The rest of the second week fades. Swell drops, wind turns onshore, and conditions get ordinary. The 18th, 19th, and 20th offer very little – small, weak, or messy. The 21st has a brief window of offshore wind and a 5ft south-southwest swell, but it’s short period and low energy. By the 23rd, it’s glassy but only 3ft, not much to get excited about.

So, the best of the bunch is Saturday the 12th and Tuesday the 15th. Both offer strong, clean swell with good wind. The 12th is bigger and more serious, the 15th is a bit more user-friendly. Don’t hold your breath for the rest.

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.
