The Lowdown
Alright, mate. Rusty here.
Well, I’ll be honest, the next few days at Praia da Barra are a bit of a write-off. This spot is a sandbar that rarely breaks, and we’re paying for that now. For the first several days, we’ve got a lot of energy in the water, but it’s all getting ripped apart by strong cross-shore winds. We’ll see some serious size – up to 12ft on the 16th – but it’s going to be a messy, lumpy, cross-chop. Not worth paddling out for.
Things finally turn around on the morning of Saturday the 19th. The wind swings offshore from the east with a light breeze, cleaning up that 7ft NW swell (combined energy is 1716). This is a proper groundswell with a 13-second period, so there’s some real power and shape to it, but at this size it’s for the experienced crew only. Saturday morning is the standout of the whole run. That offshore wind makes all the difference.
Sunday the 20th and Monday the 21st also have clean, offshore mornings. The swell drops back a notch to 6ft and then 5ft, coming from the NW with a long 11 to 12-second period. These are much more manageable and still punchy. The water temp is sitting about average for the time of year at 66°.
After that, we get a few more hits. The morning of Tuesday the 22nd is clean but small, and then Wednesday the 23rd brings back a solid 5ft WNW groundswell with a pumping 14-second period and glassy conditions. That’s another excellent session for the experienced surfer, as the energy is moderate-to-strong (1028).
The pattern carries into the second week with glassy mornings on the 24th, 25th, 26th, and the 27th of September, but the swell gets pretty inconsistent and drops off in size. You’ll get the odd waist-high wave, but nothing to write home about. Winds stay messy for the afternoons, so it’s a dawn patrol game. For an inconsistent sandbar, this forecast isn’t all bad – it just has a lot of waiting between the good windows. The real gold is locked in for Saturday the 19th morning.
Rusty.
