The Lowdown
Alright, Rusty here. Let’s break down what’s ahead for our local lineup.
First few days are a total washout. Tuesday the 21st and Wednesday the 22nd have got nothing doing – tiny scraps and messy conditions. Leave the board on the rack.
Things finally fire up on Thursday the 23rd. That morning, Barrinha is pumping with an 8-foot south swell. The wave energy is cranked up to 1752 – that’s a lot of power behind it. Wind is light and offshore, so the faces will be clean and lined up. This is big, serious surf – experts only. Beginners, stay on the sand. Water temp is about 64°, right where it should be for this time of year.
That afternoon drops to a still-chunky 7 feet, with a clean cross-offshore breeze. Good, but the morning is the main event.
By Saturday the 25th, it’s more manageable. Swell drops to around 5-5 feet from the southeast, and we’ve got offshore wind again. Combined energy is moderate (405-458). This is a sweet spot for intermediate surfers – clean, fun waves without the heavy juice.
Sunday the 26th morning is another heavy session for the experienced crew. A 8-foot south swell hits with combined energy at 1800, and a moderate offshore wind keeps things clean. Powerful and a bit intimidating – you’ll want your big-wave setup.
After that, it’s a long, flat, choppy stretch from Monday the 27th all the way through early August. Cross-onshore winds and weak, disorganized swell dominate. There’s a little blip on August 5th with a 5-foot south groundswell carrying a 13-second period, but the wind is cross-onshore and ruins it – poor conditions. A shame, because there’s some real push in that swell.
The standout session: Thursday the 23rd morning at Barrinha. 8-foot south swell, glassy offshore wind, and massive energy. This is the one to circle on the calendar for the big-wave hunters.
Best for the everyday surfer: Saturday the 25th, with 5-5 feet and clean offshore wind. It’s not massive, but it’s pure fun and well-shaped.
Expect a gap of about a week with next to no quality surf after the 27th. Make your move in late July.
Rusty.

Information about the Barrinha Surf forecast
The above surf forecast table for Barrinha provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Barrinha can be found by selecting the local surf guide option on the grey menu. Our Barrinha 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 (Barrinha) 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 Barrinha 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.
