Table - best surf conditions forecast for Barrinha over the next 16 days.
The Lowdown
Alright, Rusty here. Let's talk about what's in the water.
First off, the water temp at Barrinha is about 67°, which is pretty normal for the season.
We're in a rough patch right now. From Friday the 31st all the way through Monday the 3rd of August, it's a total bust. The swell is tiny, the wind is a messy cross-onshore, and you'd be better off waxing your board for a different day. That's a solid gap of several days with no surf worth talking about.
Things finally get a pulse on Tuesday the 4th of August. The morning brings a clean 3ft southerly swell with a solid 11-second period. The energy is moderate at 282, and that light offshore breeze will make it glassy. It's not a classic, but it's the first real chance to get wet.
Wednesday the 5th keeps that energy rolling with a 4ft southerly swell (240 energy) and clean, light winds. The waves are there, but the conditions are just ordinary. It's a good grooving session, not a standout.
Thursday the 6th has a glassy morning, but the swell is weak and short-period (8 seconds). It's a bit of a tease.
The One to Watch
The real magic is way out there. Circle Thursday the 13th of August. The morning is looking gold with a 2ft swell from the SSE, but the period is a very long 16 seconds. That's proper groundswell, and with a gentle offshore breeze, it'll be clean and lined up. The energy is 306. This is the kind of day where the waves have real shape and power.
Later that same afternoon, the swell jumps to 6ft from the south, but the period drops to a short 7 seconds. The energy is a big 692, and the wind stays clean. It'll be a bit of a close-out mess at the beach, but there could be some fun ones.
Then we get the big one. Friday the 14th and Saturday the 15th of August are for experts only. A massive 10ft to 16ft southerly swell with very long periods. The energy numbers are insane—3017 and 20996! The wind is glassy or light, but this is way too big for this break. The power is immense. For most folks, this setup looks more interesting for kite surfing than paddle surfing.
So, the bottom line: The first week is a write-off. The best session is the morning of Thursday the 13th of August for that long-period groundswell. That's your shot. The weekend after that is for the big dogs and the brave.
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.
