Barra do Sul Surf Forecast and Surf Report

Alright mate, Rusty here with the lowdown for Barra do Sul, this time in feet and Fahrenheit, same honest take.

Overall this stretch ain't gonna blow your mind, but there are a few windows where everything clicks. First few days are pretty flat and ordinary, then we get a cleaner patch mid-period, and a nice spike right at the end. Water temp is about average for this time of year, nothing weird.

Monday July 6 starts tiny – 2ft SE swell, 10-second period, energy around 178 (moderate). Morning is clean with a cross-off breeze, but the waves are very ordinary. Afternoon turns glassy but still tiny. Not worth suiting up.

Tuesday July 7 morning shows 4ft SE swell, same 10-second period, energy 236 (moderate), with light offshore wind and clean conditions. That’s surfable – small but fun for a beginner spot. Afternoon goes onshore, so hit it early.

Wednesday July 8 drops back to 2ft with light offshore wind, energy weak at 103. Ordinary. Afternoon onshore, no good.

Thursday July 9 and Friday July 10 stay small and ordinary. Friday morning has 1ft ESE swell with a 14-second period – long-period but tiny, energy 104. Clean but too small to bother.

Saturday July 11 – now we’re talking. Morning and afternoon both offer 3ft ESE swell, 13-second period, with glassy conditions. Energy hits 332–338 (moderate). That’s clean, glassy, small but fun for beginners or a longboard. Crowds can happen sometimes, but it’ll be worth it.

Sunday July 12 afternoon is glassy again with 3ft ESE (13s, energy 238) – good conditions. Morning is cross-on, but the afternoon is a solid backup.

Monday July 13 morning: 3ft SSE swell (10s, energy 244), clean cross-off wind. Good for the size. Afternoon gets hammered by 30 km/h winds and 4ft SE swell – messy, more of a kite day than paddle.

Tuesday July 14 shines again. Morning 4ft SE (9s, energy 214), clean cross-off. Afternoon stays clean with 4ft SE (11s, energy 283) and light cross-off. Both are good, consistent sessions.

Wednesday July 15 through Friday July 17 drop back to small, ordinary or cross-on conditions. Not much happening.

Saturday July 18 stays small and ordinary.

Sunday July 19 morning is the standout of the whole forecast. 5ft E swell with an 8-second period, but glassy wind. Energy is 398 (strong) – the biggest, most energetic swell of the run. The short period means punchy, steep waves – might close out a bit at the beach, but with glassy conditions this is the pick of the period. Afternoon gets cross-on and drops off.

Monday July 20 morning: glassy with 3ft ESE (10s, energy 334), clean. Afternoon gets bigger at 5ft E (10s, energy 564) but cross-on makes it marginal.

Tuesday July 21 morning ends the outlook with glassy 4ft E swell (10s, energy 279) – clean and fun.

Bottom line: Saturday July 11 and Sunday July 19 (morning) are your best bets. That Sunday morning has the most energy and perfect glass – circle it.

Long-range stuff is always a little dicey, but the signs are good. Forecasts can change, so keep an eye out.

Rusty.
