The Lowdown

Yo, what’s up surfers, Rusty here. Alright, let’s look at what’s on the menu for Barra do Sul over the next couple of weeks. Fair warning, it’s a slow start and a very patchy run, but there are a couple of windows where things line up nicely if you’re willing to wait.

The water temp here is sitting right around 66°F, which is pretty much spot on average for this time of year, so no surprises there.

We kick off with a bit of a lull. The first few days are mostly poor with small, weak energy and short period (8 seconds) swell on Tuesday the 21st. It’s not until Wednesday the 22nd morning we get a glimmer, with a glassy 3ft wave from the east, but it’s still just ordinary. Thursday and Friday morning are largely a write-off with cross-onshore wind and choppy conditions.

The first real standout window opens up on Friday afternoon, July 24th. It’s not huge, but glassy conditions with a 4ft south-east swell (period 10 seconds) and moderate energy. That’s clean, rideable surf. The next morning, Saturday the 25th, sees a cleaner cross-offshore wind from the northwest with a 3ft south-east swell. Nice and clean again morning of the 26th with offshore west wind, though still small.

Then we hit a long dry spell. From the afternoon of the 26th through the 28th, the surf drops off and gets messy. The 29th and 30th have tiny waves with weak energy, mostly below 3ft. The 31st stays small and ordinary. That’s a solid few days with nothing to get excited about.

But, hang in there, because the second week starts to look promising. Saturday morning, August 1st, brings a standout session. It’s glassy and calm, and the swell jumps up in quality. It’s a 3ft south-southeast groundswell with a long 12-second period and solid wave energy. That’s a proper, clean groundswell – much better shape and punch for its size. The afternoon gets ruined by onshore wind, so it’s a morning-only call.

Sunday morning, August 2nd, is another cracker. Glassy conditions and a 4ft east swell (8 seconds) with strong energy. A touch of size, clean, and fun for the experienced. Monday morning the 3rd is also glassy with a 3ft south-east swell and a long 12-second period, worth a paddle.

The absolute highlight, though, is Tuesday afternoon, August 4th. We’ve got glassy conditions, a 3ft south-east swell with a very long 14-second period, and the combined wave energy is cranking. That’s a serious groundswell, clean and full of power. This is the one to circle on the calendar. Morning of the 4th is also marginal but promising. After that, the wind gets messy again on the 5th, so grab that window.

Overall, it’s a patchy forecast, but if you hit Friday the 24th afternoon or the glassy mornings of August 1st, 2nd, and especially Tuesday the 4th afternoon, you’ll find clean, fun waves. The long period swells will be best for breaks that handle them.

Stay stoked,
Rusty
