The Lowdown
Alright, Rusty here again, giving you the same read in the old measurements.
The water’s sitting at 63°F, which is about 3°F colder than normal for this time of year. You’ll definitely feel that first splash.
The first few days are a total bust. Monday through Wednesday next week are tiny and messy. Thursday the 23rd shows some life. The morning brings a clean 5ft swell from the south with a light offshore wind, but it’s still a bit weak with a combined energy of 258 (moderate). The afternoon picks up to 6ft from the SSE, and the energy jumps to 838 (strong), but it’s only a marginal call. The period is a short 8 seconds, so it’ll be a bit lumpy.
The real standout is Sunday the 26th. That morning it’s clean with 6ft from the ESE, pushing in with a solid 9-second period. The combined energy is a thumping 827 (strong), and the wind is pure offshore from the WSW. This is the best on offer. The waves will have some real punch, but at 6ft it’s getting into the territory where beginners might want to watch from the sand. Monday the 27th morning is also a gem, with glassy conditions and 4ft of clean ESE groundswell (energy 352 – moderate). Expect some company in the lineup here.
After that, it fades out. The second week is mostly weak, with a few tiny, glassy moments on the 1st and 2nd of August, but nothing worth the paddle. It’s a waiting game after that Sunday.
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.
