The Lowdown
Alright, Rusty here. Let's have a look at what’s shaping up for Praia da Barra over the next couple of weeks. The water temp’s sitting pretty average for the time of year, so no chilly surprises there.
Right off the bat, there’s nothing worth paddling out for until Thursday the 20th. The 19th is a write-off with tiny, weak swell and poor conditions. We’re looking at a couple of days of waiting.
The first real glimmer of hope comes Thursday morning, the 20th. It’s small, only 2 ft from the WNW, but the wind goes glassy. It’s surfable, but honestly, it’s pretty ordinary and the energy is weak (101). That’s really just a warm-up if you’re desperate.
The wind gets nasty on Thursday afternoon and pretty much wrecks things through Friday the 21st. Friday morning has a bit of size at 7 ft from the NNW (870 energy), but it’s cross-shore wind and the report calls it marginal. Friday arvo is just messy with a 35 km/h cross-wind.
Saturday the 22nd morning is the first proper standout for a surf. 5 ft from the NNW with glassy conditions – that’s clean. It’s a sandbar break, and it’s inconsistent and rarely breaks, so you’ve gotta pick your moment and manage expectations, but when it’s on, it’ll be fun. Crowds are only a *sometimes* thing here. The swell period is short at 7 seconds, so don't expect any grunty barrels, but it’s a real chance for a cruise.
Sunday the 23rd morning looks interesting with a clean 7 ft from the NNW (538 energy) and cross-offshore wind, but it’s marked as marginal due to tide. That one’s for the intermediate crew who know the bank.
After Sunday, the outlook gets sketchy again with onshore winds and chop through Monday and Tuesday the 24th-25th. Wednesday the 26th morning sees a return: 6 ft from the WNW with clean, cross-off winds. That’s another good window if you’re free. Energy is moderate (432).
Now, look a week ahead to Thursday the 27th morning: we’ve got a 7 ft NNW swell (923 energy) with light cross-winds. That’s a bigger, more powerful day but again, the tide might be tricky.
Friday the 28th morning is the absolute pick of the whole forecast to my eyes. 5 ft from the NW (499 energy), with completely glassy conditions. Zero wind. That’s a perfect setup for this spot. It’s clean, it’s got some push to it, and the period is a decent 10 seconds. If you only get one session in the next fortnight, make it that one.
The following week has some real size but mixed wind. Monday the 31st morning pumps a 7 ft NW groundswell (1545 energy) with a 13-second period. That’s a long-period swell that can make a beach break like this a bit too straight and closey, but the energy is massive. The wind is cross-shore, so it’s not perfect. This one is best left for the experienced crew, as 8 ft on Tuesday the 1st is expert territory with that power.
The final standout is Wednesday morning, 2nd of September. 5 ft from the NNW (535 energy) and glassy again. That’s another clean, fun-sized morning with good energy.
Overall: the first week is lean and choppy. The real gold is on Saturday 22nd morning and Friday 28th morning for clean conditions. The bigger stuff late in the month (Aug 31 – Sep 1) has power but needs an expert to handle the lump and the period. Keep your eyes on that Friday 28th.
Rusty.
