The Lowdown
Right, let’s have a look at what’s on the table for Barra do Sul over the next couple of weeks. It’s a bit of a mixed bag, but there are a couple of windows that’ll get you in the water.
The first few days are pretty average. That Sunday afternoon, the 23rd, is a write-off with poor surf and a cross-on wind. The water is a touch warmer than normal for this time of year at 68°. Monday and Tuesday just aren’t doing much either – small, messy, and the scores are just not there.
But then, Wednesday the 26th is where it starts to get interesting. The morning shows glassy conditions with a 3ft swell from the SE, period of 15 seconds – that’s proper groundswell, lots of energy (459). The afternoon cleans up even more, still glassy, same swell, and the energy jumps to 520. The comment says “very good surf conditions,” and that’s the standout of the week. The swell is a bit on the smaller side, but with that period and offshore glass, it’ll be lined up and clean. This is your best bet for a proper session.
Thursday morning holds on with clean, cross-off winds and a 3ft SE swell, still good, but it drops off in the afternoon. From Friday the 28th through the weekend, the wind swings around, the swell goes short period and choppy. It gets ugly. Not worth paddling out.
The following week starts with a bit of a reset. Sunday the 30th and Monday the 31st mornings have clean conditions with E swell around 4ft to 4ft and good energy. The wind is light and offshore or cross-off. That’s a solid pick for a few fun waves. Tuesday the 1st of September has a stiffer offshore wind, but the swell drops a bit.
Then there’s a bit of a gap. The rest of the week into the next weekend is mostly onshore, poor, or just marginal. Not much to get excited about.
The real gem in the whole 16-day window is Wednesday the 26th of August. That’s the one to mark on the calendar. Glassy, 3ft, 15-second groundswell – it’s going to be clean and fun. The Wednesday afternoon is the pick of the entire run.
So, get out there on the 26th. Don’t waste your time on the junky days. The water’s a touch warmer than usual, so you might not need a full winter suit, but still don’t be a hero.
