The Lowdown
Alright folks, Rusty here. Let’s get into it for this stretch of coast. The only spot we’ve got on the radar is Barrinha, and to be honest, the first week is pretty grim. We’re looking at a long waiting game – about a full week of nothing worth paddling out for, with only tiny, wind-affected dribble on offer. The water temp is sitting at 67°, which is about average for the time of year, so nothing weird there.
The real story starts to build from Tuesday the 10th of August. We get a solid pulse of south swell pushing through, and the winds finally play ball. Monday morning the 10th sees a clean 8ft south swell with a gentle offshore wind from the WSW. That’s a proper session, though the period is a short 8 seconds, so it’ll be a bit lumpy and close together – better for the more experienced crew. By Tuesday morning the 11th, it gets even better. Glassy conditions, an 8ft south swell, and the period jumps to 13 seconds. That’s real groundswell energy, and the combined energy reading is a massive 2175 (strong). This is the standout of the whole forecast. The waves are clean, powerful, and for experienced surfers only – this is too big for beginners. Wednesday the 12th keeps the good run going with an 8ft south swell and clean cross-offshore winds in the morning, so you’ve got a solid three-day window of quality.
The standout here is Tuesday the 11th – glassy conditions, a long-period 8ft south groundswell, and the energy is pumping. That’s the one to mark on the calendar. After that, the wind turns onshore from the 14th, and the swell starts to fade, so the window closes. Keep an eye on the forecast, though; it tends not to stay poor for long around here.
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.
