The Lowdown
Alright, let’s talk in feet and miles. Barrinha is dead flat to start. Sunday the 19th and Monday the 20th – nothing. Tiny slop, onshore winds, don’t bother. Tuesday the 21st: a little 2-foot south swell shows up, period 10 seconds, glassy in the morning. Surfable but ordinary, energy weak (111). First sign of life.
Thursday the 23rd brings a proper southerly groundswell. Morning: 5.6 feet from the south, period 8 seconds, cross-off wind, energy 415. Afternoon: 6.2 feet from the SSE, period 9 seconds, energy 526. Clean but marginal tide. Still, real waves.
The standout is Friday the 24th. Morning: 5.6 feet from the southeast – that’s the sweet spot for Barrinha – period 9 seconds, energy 466. Light cross-off wind, so the waves will be clean and lined up. Water temp is 62.6°F, about 3.2°F colder than normal – a bit chilly, but you’ll be in the water. Crowds sometimes, so get there early. This is the best session in the whole 16 days.
Saturday the 25th drops off – onshore, 3.3 feet, no. Sunday the 26th choppy. Monday the 27th: 3.3 feet from the south, period 14 seconds – long-period groundswell, glassy in the morning, energy 491. Clean but smaller. Solid backup.
The rest of the week into early August has a few pulses: Tuesday the 30th has 4.3 feet with cross-off wind, moderate energy (257). Sunday the 2nd of August afternoon: 5.6 feet from the northeast, period only 6 seconds – short and weak, but clean. Not a standout.
Bottom line: Friday the 24th of July is your day. Monday the 27th is a good second choice if you like glass. Everything else is hit or miss. Barrinha usually bounces back

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.
