The Lowdown
G’day, this is Rusty. Let’s talk about Barra do Sul. The next week and a half is a bit of a mixed bag. We’ve got a few mornings with some clean, small waves, but the afternoons are mostly a write-off with the wind turning onshore. The standout window is a good week away on Monday the 10th of August, where we finally see a solid pulse of swell and decent conditions. Before that, it’s a lot of waiting.
Starting off now, Monday the 3rd of August, there’s surfable waves at 2ft from the east, but the conditions are very ordinary. The morning is glassy at 3 mph wind, and the water is 67°, which is a touch warmer than normal for this time of year. The combined wave energy is weak (57). By the afternoon, the wind swings around to the east-northeast at 6 mph, and it’s a cross-on mess, so no good.
Tuesday the 4th is more of the same. Morning glass at 2ft, energy weak (61). Afternoon crumbles. Wednesday the 5th, a clear morning, tiny 2ft with glassy conditions, but the combined energy is still low (87). Thursday the 6th shows a slight bump in the morning with 3ft from the east and a clean cross-off breeze, and the energy creeps into the moderate range (102). Not a standout, but a sessionable little bank. The rest of the week through to Sunday the 9th is a frustrating run of onshore winds and deteriorating surf, with Saturday the 8th morning offering a brief glassy window at 3ft and moderate energy (109), but it’s still very ordinary.
Now for the real news. Monday the 10th of August is the one to circle. The morning brings a solid 5ft swell from the south-southeast, with a clean cross-off wind from the south-southwest at 6 mph. The combined energy jumps to 312 (moderate). The afternoon gets even better: 7ft from the same direction, still cross-off at 6 mph, and the energy rockets up to 755 (strong). This is the best on offer—clean, powerful, and worth the wait. The 7ft is going to be a step up, so it’s for experienced surfers only.
The rest of the second week tapers off. Tuesday the 11th and Wednesday the 12th have clean cross-off winds but the swell drops to 3ft and 2ft, and the energy falls back to moderate. There’s a long-period groundswell peaking on Friday the 14th of August, with a 16-second period from the southeast offering 3ft and very strong energy (541), but the wind is a light cross-on. The period is very long, so this will be a straight, fast wave for a point or reef, not a beachie. Saturday the 15th morning is clean but tiny at 2ft. Sunday the 16th of August morning has a clean 5ft from the east, but it’s short period (7 seconds) and the afternoon is onshore. Not a stand-out, but a decent last look.
Crowds at Barra do Sul are sometimes an issue, so you might have company, especially on the good days. The best call is definitely Monday the 10th of August—morning for the build, afternoon for the peak. Keep an eye on it.
