The Lowdown
Alright, Rusty here. Let's break down what's happening at Barrinha.
The first real chance to get wet is Sunday morning, August 23rd. You've got a clean 2.0m south swell with an 11-second period, a decent moderate energy setup (1022), and a light cross-offshore breeze. Water temp is nothing unusual for this time of year. Sunday afternoon, the swell jumps to 2.3m, but the wind goes cross-shore and picks up, so it gets a bit bumpy.
Monday the 24th is your standout. Monday morning is the pick of the whole run. A solid 2.5m south swell with a 14-second period – that's serious energy (3029). The wind is dead flat, glassy. That means clean, powerful waves. It's going to be too big for beginners, but for the experienced crew, that's as good as it gets. Monday afternoon keeps the 2.5m swell, but a light cross-shore breeze puts a few ripples on it.
Tuesday the 25th fades. The swell drops to 2.0m, and the wind turns cross-onshore, getting choppy by the afternoon. Wednesday the 26th and Thursday the 27th are poor with onshore winds and messy conditions. Swell energy drops right off into the weekend of the 29th and 30th, with tiny waves.
But then, Monday, August 31st offers a late comeback. The morning bumps up to 2.5m from the ESE, with an 8-second period (moderate energy at 1053). It's clean with a light cross-offshore breeze. That morning looks good again. Early September is a mix of small, clean but weak swells. By September 7th, it's flat with 0.1m waves.
The clear winner here: Monday morning, August 24th. Glassy, 2.5m south groundswell. If you can handle the size, that's the session to lock in.
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.
