The Lowdown
Alright, let’s get into it. This is Rusty, and I’m looking at the next stretch for Barrinha. It’s a fairly exposed spot, so it catches most of what’s coming, but the wind and the swell size are going to keep things interesting. The water temperature is about average for the time of year, nothing too crazy.
Right now, we’re staring at a long, frustrating flat spell. From Tuesday the 28th of July all the way through the end of the week and into the start of August, there’s just no real surf to speak of. We’ve got tiny 0.6 ft to 3 ft waves, mostly from the south, with crappy cross-onshore or howling northerly winds. The energy is weak. Not worth paddling out for. Even the glassy moments on Thursday afternoon (30th) with 2 ft and glassy wind are still too small to get excited about. It’s a dry spell that drags on for nearly a week.
Now, you want a real standout? Mark your calendar for Tuesday the 4th of August. Monday the 3rd is still flat junk, but Tuesday morning arrives with a pulse. We get 4 ft of swell from the south with an 11-second period – that’s proper long-period groundswell. The energy is moderate-strong. The wind is glassy. It’s going to be clean, lined-up, and hollow on the reef. That’s the pick of the whole outlook. Afternoon gets a bit bumpier with a 9 mph cross-off, but the morning session should be pure magic. It’s going to be a bit of a session for the intermediates – not too big, but more than enough push.
Another day to keep an eye on is Monday the 10th of August. After another gap of a few days with junkier waves and onshore winds, Monday morning delivers again. 4 ft from the south, 11-second period, strong energy, and glassy. That’s a clean, long-period south swell. It’s worth a paddle. Tuesday the 11th of August also looks solid with 4 ft from the south-southeast, clean offshore winds from the south-southwest, and clean wave faces.
Overall, it’s a slow start and a lot of waiting, but a couple of proper glassy south groundswells show up in the first half of August. The 4th and 10th are your best bets.

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.
