The Lowdown
Alright, this is Rusty with the lowdown on Barra Vento for the next 16 days. Let's get straight to it: for the first part, you're better off waxing your car than your board.
We've got moderate wave energy hitting the coast (peaking around 543), but it's a total mess. Strong SE winds are smashing the swell, making it choppy and cross-onshore from Tuesday the 18th through the 20th. The water's at 79°, which is dead average for the season, but it's not going to warm you up. Just forget it.
Then there's a real lull. A few days of next to nothing. Don't hold your breath.
The first true highlight is the morning of Friday, August 21st. The wind goes dead calm, glassy as a mirror, coming out of the NNW at just 3 mph. The swell is small at 1 meter from the ESE, short period at 8 seconds, and weak energy (126). It's nothing for a heavy shortboard, but for a clean, empty peak on a longboard, it's gold. Crowds are rare, so you might luck out.
Now, for the one real standout you should circle on your calendar: Saturday morning, August 29th. This is the pick of the bunch. The wind will be offshore out of the NNE at 6 mph, cleaning the lines up perfectly. The wave energy is moderate (163), with a 1.0m swell from the ESE at 8 seconds. This is textbook beginner-to-intermediate goodness: clean, waist-high, and uncrowded. The offshore breeze will keep it from closing out.
Later on, Wednesday morning, September 2nd, sees a bump in size to 1.5m from the ENE, but the wind goes cross-shore, so it'll be a little lumpy. It's a looker, not a lock.
Overall, the second week is a lot of nothing special. Stick to the two windows I've told you about, and you'll get the best of what's on offer.
Rusty.

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 Barra Vento 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.
