The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s in store for us at Barra do Sul over the next couple of weeks.
Overall, the pattern is pretty quiet. We’ve got a bit of a slow start, and then a few flashes of better energy, but you’ll need to pick your windows carefully. The water temperature is sitting at 66°, which is a touch warmer than average for this time of year – nothing crazy, but a nice little bonus for the feet.
The first real standout is Friday morning, the 24th of July. That’s where we see a solid jump in energy. The combined swell energy hits 584 (moderate to strong), with a 6ft swell coming from the SSE. The period is 9 seconds, so it’s a bit of a short-interval swell, but it’ll have some push. The wind is a light cross-offshore from the SSW at just 3 mph, which will keep the surface clean. This is the best on offer for the whole period – it’s not huge, but the conditions are set up nicely. Just be aware that at 6ft, it’s starting to get a bit much for beginners.
After that, we drop back into smaller, more ordinary surf. Saturday morning the 25th and Sunday morning the 26th both have glassy conditions with the wind going light and variable, but the swell is only around 3ft to 3ft from the SE, with weak energy in the 130-170 range. It’s surfable, but nothing to write home about. The afternoons get chopped up by light cross-onshore winds, so morning sessions are the way to go.
Then there’s a long dry spell. From the 27th of July through to the 2nd of August, the waves just don’t show up. The swell drops to 1ft to 2ft, and the energy is pitiful – mostly under 60. Even though the wind is often glassy or light offshore, there’s just no wave to ride. It’s a blank stretch of about a week.
We finally see a pulse of energy return on Monday the 3rd of August. The swell picks up to 3ft to 3ft from the SE, with a period of 10 seconds and combined energy around 250 (moderate). The wind is light cross-shore or cross-on, so it’s a bit messy, but there’s life in the water again. The best of this new pulse looks like Tuesday morning, the 4th of August, with a 3ft SE swell, 10-second period, and a clean offshore wind from the WNW at just 3 mph. The energy is still moderate at 204, but it’s clean and rideable. After that, the swell fades again through the rest of the week.
For a beginner spot like Barra do Sul, the standout session is hands-down Friday morning, July 24th – that’s the one to aim for with the biggest swell and cleanest conditions. The Tuesday morning on August 4th is a decent backup if you miss that first window. Keep an eye on the forecasts, because this stretch of small surf is pretty typical for the area, but it won’t stay this way forever.
Rusty.
