The Lowdown
Alright, Rusty here. Let’s chew over what’s coming for Barra do Sul.
Water temps are sitting at about 63°, which is a couple degrees colder than usual – you’ll want a thicker suit.
The forecast is mostly quiet to start. From Thursday the 16th through Thursday the 23rd, the swell hangs around 3 to 4 ft, coming from the east or east-southeast, with periods mostly 8 seconds. The combined wave energy is in the moderate range (100 to 210). The mornings are the only real chance – glassy or clean with light westerly or northwesterly breezes. The afternoons get light cross-onshore winds that mess up the surface. It’s a long stretch of ordinary, surfable but nothing to write home about.
Then things perk up Friday the 24th. Friday afternoon, a pulse pushes in: 5 ft from the southeast, 8-second period, with a combined energy of 411 (moderate to strong). The wind goes offshore from the northwest, so it should be clean. That’s your first real standout.
Saturday the 25th morning is the best of the whole run. You’ve got 4 ft from the southeast, 9-second period, with a clean offshore breeze from the west-southwest at 12 mph. Combined energy is 210. This is the pick – good, clean, surfable waves.
Sunday the 26th morning is smaller – 3 ft, southeast, 8-second period – but still clean with light cross-offshore winds. The afternoon gets choppy.
From Monday the 27th onward, it drops back to small, ordinary surf – around 2 to 4 ft, mostly east or east-southeast, periods 7 to 9 seconds. The last decent chance is Friday the 31st morning: 3 ft from east-southeast, an 11-second period (longer period), glassy conditions, combined energy at 202. Promising but small.
Best bet? Saturday the 25th morning. Friday the 24th afternoon is also worth a look if you can swing it. Otherwise, pick your glassy mornings and make the most of what’s on offer.
Rusty.
