The Lowdown

Alright, here’s the rundown for Barra do Sul. It’s a bit of a slow start and a whole lot of waiting, but there are a couple of windows where it could light up.

The next couple of weeks are looking pretty underwhelming, to be honest. We’ve got a lot of small, weak surf and onshore winds messing things up. The swell energy is mostly in the low to moderate range, with values like 221 and 261 early on, but it’s pretty short-period stuff that won’t have much push.

Monday the 14th is probably the best of the first few days. We’re looking at chest-high waves, around 4ft, from the SSE. The wind is cross-offshore, which will keep things reasonably clean, and the energy is moderate (221). It’s not going to be a classic, but it’s surfable.

After that, it fades fast. Tuesday the 15th drops to knee-high, and the wind swings onshore, making it messy. Then we get a run of pretty poor conditions right through to Friday the 18th – small, choppy, and mostly cross-onshore. The energy stays weak, values like 121 and 140.

The weekend gets bigger but not better. Saturday the 19th sees the swell jump to 6ft and then 7ft, but the period is only 8 seconds and the wind is a moderate cross-onshore. It’s going to be a jumbled mess – this is more of a kite-surfing setup than a paddle-surfing one. The energy is strong, with values of 455 and 1041, but it’s just not clean.

Now, here’s where it gets interesting. Sunday the 20th and Monday the 21st are your standouts. The swell backs down a bit to 5ft and 4ft, but the period bumps up to 9 seconds and the wind goes glassy offshore. Sunday morning especially looks clean with good energy (394). The direction is East, which is solid for this spot. It’s not huge, but it’ll be the cleanest, most lined-up surf of the whole run. Monday morning will be similar but slightly smaller.

After that, it’s back to the usual story – small, weak, and choppy. There’s a brief glassy spell on Tuesday the 22nd with 4ft, but the afternoon wind ruins it. Then we get a long stretch of poor surf from the 23rd right through to the end of the period. Wave heights stay under 3ft, periods are short, and the wind is mostly onshore or cross-onshore. The energy is weak, with values mostly below 200.

So, bottom line: don’t hold your breath for most of this forecast. If you’ve got a window, make it Sunday the 20th or Monday the 21st. Those are the days it’ll be worth paddling out. The rest is a waiting game.
