Hey guys, Rusty here with the long-range look for the break. Let’s get into it.
It’s a slow start, but the second half of the window has some real meat. The big news is a strong south swell that shows up late in the month.
We kick off on Monday, July 13th morning at Ribanceira. There’s a clean 7ft of south swell with an 8-second period. Wind is a light offshore breeze from the west-southwest, so the surface will be tidy. The wave energy is 1089 – that’s a good solid push. It’s a fun, rideable day. The afternoon gets messy, so hit the morning.
Tuesday, July 14th morning the swell backs down to 6ft from the southeast, but the period stretches to 10 seconds. The wind is flat calm – glassy. Dead still. The wave energy is still a healthy 614. A total treat. Water temp is about average.
From Wednesday, July 15th through Monday, July 20th, the surf goes completely flat. The swell drops to nothing and the wind is rubbish – mostly onshore. Over a week of blank days. Nothing to do but wait.
Tuesday, July 21st shows a tiny 2ft south swell, but the period in the afternoon hits a very long 14 seconds, which is true groundswell. Light offshore wind. The wave energy is weak (282), so you’ll be hunting for scraps, but it’s a sign of life.
Wednesday, July 22nd is where it gets good. The morning has a clean 5ft southeast swell with a 12-second period and a light offshore wind from the southwest. Energy is 569. Good shape. The afternoon is even cleaner with the wind going near-still again and the swell at 4ft. A very solid day.
Then comes the standout. Saturday, July 25th morning. This is the one. 7ft of south swell, 10-second period, and glassy. Zero wind. The wave energy is 1530 – that’s a strong, powerful swell. For a sandbar, this is a prime session. A bit big for groms, but for everyone else, this is the day.
Sunday, July 26th morning is for the big dogs. 8ft of south-southeast swell with a 14-second period. The wind is a gentle offshore breeze from the southwest. The wave energy is a massive 2568 – that’s very strong. Big, powerful groundswell with clean conditions. Experts only, but it’s excellent. The afternoon stays clean with 7ft.
After that, the swell fades and the wind turns onshore again through the end of the month.
So your picks: Saturday, July 25th morning for the glassy, powerful session, and Sunday, July 26th morning for the biggest, cleanest groundswell of the run for those with the skill.
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.
