The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Barra do Sul over the next couple of weeks.
Overall, it’s a bit of a slow start, but there’s a couple of sessions that are worth circling on the calendar. The first real surf we see kicks off Wednesday morning, but it’s nothing to write home about.
Wednesday, September 2nd starts with a bit of rain and a cross-shore breeze. We’ve got a 6ft swell from the SSE, but the energy is all over the place (1003) and the conditions are average. The afternoon drops off to 4ft, and the wind swings onshore. Not the day to rush out.
Thursday, September 3rd is a bit of a tease. The morning is clean with a light cross-offshore breeze from the north. Swell is 4ft from the SE with a solid 11-second period, and the energy is moderate (297). The water temp is about average for the time of year. It’s a small, clean day, but nothing pumping. The afternoon gets blown out.
The rest of the week into the weekend is a write-off. Thursday afternoon through to Monday, September 7th, is a mix of poor surf, small waves, and crummy winds. Swell drops below 3ft, and the energy is weak. There’s a gap of about four days with no real recommendations.
Tuesday, September 8th morning shows a little glimmer. A 3ft swell from the SE with a long 12-second period, light cross-offshore wind, and clean conditions. Energy is moderate (209). It’s a small, clean wave for the patient surfer.
Wednesday, September 9th has a bit more size (5ft to 6ft), but the wind is onshore and the period is short (7 seconds). Choppy and messy.
Thursday, September 10th afternoon is a standout, but it’s a tricky one. We’ve got a solid 10ft swell from the ENE, with very strong energy (2158). The wind is light and cross-onshore, but the file says it’s too big for this break. This is only for the experts, and even then, it’s pushing the limits. Not a beginner’s day.
Friday, September 11th morning is the real highlight. The wind goes glassy, dead calm. Swell is a solid 7ft from the E with a long 11-second period and strong energy (1001). The conditions are described as excellent for experienced surfers. This is the session to aim for. It’s a serious, powerful groundswell, so expect better shape and longer lulls between sets.
After that, the surf fades again. Sunday, September 13th brings strong winds and messy conditions. The following week looks pretty average until Tuesday, September 15th, when we get a nice run. The morning is glassy with a 5ft swell from the ESE, moderate energy (393), and clean conditions. The afternoon steps up with a light cross-offshore wind and very good conditions (520 energy). This is a solid day for a longer session.
Wednesday, September 16th and Thursday, September 17th have some residual swell, but the wind is onshore or cross, so it’s not as clean.
So, the best bet is Friday morning, September 11th, when the swell is solid and the wind is glassy. For a more manageable day, Tuesday, September 15th offers a good combo of size and clean conditions. Keep an eye on that Thursday the 10th if you’re a hardcore charger, but know it’s going to be big.
Rusty.
